<Fishscene>
Greetings. I'm trying to log into Ubuntu 11.04 using the 1720 from disklessworkstations.com. When I log in, the screen drops to a terminal saying something with the lines "spurious response..." and dumps me back to the login screen. What should I do to diagnose/resolve this?
02:23
I checked the Xorg.0.log and it doesn't seem helpful.. as far as I can tell, it logs setting up the devices, then sits there for a while and closes all devices/connections
02:24
..but that might be on my server. I'm pretty confused at the moment.

I have problems with the proper start of X sessions (gnome, unity, etc.) on a fresh LTSP fat client installation (Ubuntu 11.04).
08:15
Has anyone experience with recent fat clients? How could I debug ldm or the session start script, for example?
08:16
<Appiah>
well what's the problem
08:16
with this "proper" start
08:17
<mnieper_>
Problem is that X starts up after I log into ldm. Nautilus and Compiz run but neither gnome-panel nor the application menu, etc.
08:18
<Appiah>
if you turn off compiz , does gnome-panel launch?
08:18
<mnieper_>
Using nautilus, I can open a gnome terminal and enter "unity --replace" for example. Then Unity runs.
08:18
Wait a moment, let me check without compiz
08:19
<Appiah>
this looks like a known bug/issue
08:19
and not ltsp related
08:20
https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/542343 , http://ubuntuforums.org/showthread.php?t=1632444 (example)
08:23
<mnieper_>
When I choose the classic gnome session without compiz, it works. Afterwards it worked also when I chose classic gnome with 3D. But with session Ubuntu (= unity) it still does not work.
08:24
Thanks for pointing out the bug report; will read it now.
08:25
<Appiah>
https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/819394
08:25
Unity fails to load (only Nautilus and Compiz seem to be running).
08:25
might be related
08:32
<mnieper_>
The second bug report is my own one :-) --- As to the first: Gnome (even with 3D) seems to run stable now as long as I don't have the LDM_XSESSION variable set.
08:32
The problem with Unity remains. Do you know where the session start is logged so that I can investigate?
08:35
<Appiah>
should be some xsession-log somewhere
08:38
<muppis>
Hmm.. HP uses gPXE in their fiber-nics. :)
08:44
<mnieper_>
@Appiah: This is what I have in xsession-errors in my home directory after trying to start unity: http://pastebin.com/pxUvAij6
09:02
Hmm... in /usr/share/gnome-session/sessions/gnome-session, there is an entry "Required-panel=gnome-shell". In ubuntu.session, there is simply "Required-panel=compiz"
09:02
I wonder where the unity launcher, etc. is started

Guess I have to find a Unity channel :-) I am just wondering why I have this problem with an LTSP fat client but not with a standalone desktop!
09:29

true , but I have no idea on how to debug

@Appiah: FYI: I have found a (partial) solution for my Unity problem: I had to activate Unity as a compiz plugin by hand.

@Appiah: Will go through the ldm startup scripts... maybe I find a hint. By the way, I have another problem: Where is the cups server in /etc/cups/client.conf set? Do you possibly know?
12:36
<Appiah>
you can put cups settings in lts.conf
12:37
<mnieper_>
At the moment it is set to the LDM_SERVER, which is wrong in my installation.

@Appiah: Great! Thanks!
12:39
<Appiah>
CUPS_SERVER = x.x.x.x
12:39
then the client.conf should get that
12:41
<mnieper_>
Perfect!
12:41drdata has joined IRC (drdata!~drdata@pool-173-57-189-158.dllstx.fios.verizon.net)
12:41
<mnieper_>
Works now.
12:42
<Appiah>
so what's the problem after you just enabled compiz via unity?
12:43
<mnieper_>
WRT cups: Unfortunately, it is hard to find a recent lts.conf documentation. Even http://manpages.ubuntu.com/manpages/natty/man5/lts.conf.5.html does not mention CUPS_SERVER.
12:43
WRT unity: The problem is the other way round.
12:43
Unity (the panel, launcher, etc.) is implemented as a compiz plugin.
12:44
Somehow, the plugin was disabled although I started from scratch.
12:44
<Appiah>
in the ltsp-docs package (or whatever the name is) there should be a full list of lts.conf options
12:44
<mnieper_>
The non-ldm start process obviously enables the plugin at some point.
12:45
<Appiah>
wtf
12:45
that's the most recent one
12:46
found a mailing list saying the same on jaunty
12:46
"it's not in the docs but the function is there"
12:46
*sigh*
12:46
<mnieper_>
:-) It has to because CUPS_SERVER works here...
12:47
My main problem is to locate the scripts which actually read those variables... then I could understand what they do and which are there
12:48
<Appiah>
I remeber when there was no lts.conf manpage in ubuntu , and I complained a'lot about it
12:48
well not just ubuntu
12:49
<Hyperbyte>
And then someone came along, who, instead of complained, rolled up his sleeves and started writing. And we all lived happily ever after. :-)
12:49
<Appiah>
I got "it was on the way" and the doc team was working on it
12:50

You mean like trying for an hour to see why your code is no longer firing events after the objects have repopulated with new data and ending up reimplementing how it all works only to go down a 50 lines to see that you were disabling the signal chain on another operation you forgot about?
16:44

alkisg: screen_07 does not automatically log in, and instead the screen flashes on and off
18:03
<alkisg>
There shouldn't be any login process involved
18:03
<_UsUrPeR_>
my intention was to get a working google-chrome kiosk
18:03
<alkisg>
I.e. if you see LDM at all, it's a problem
18:03
<_UsUrPeR_>
correct. by "login" I mean it does not open X
18:03
nor does google-chrome appear. instead it flashes a terminal screen evfery so often with an error
18:03
<alkisg>
If you switch to vt2 (alt+ctrl+f2), are you automatically switched back to vt7 after a few seconds?
18:03
<_UsUrPeR_>
yes
18:04
The error appears to be an xserver error
18:04
oh, addendum: I am running 10.04
18:04
<alkisg>
What does the error say?
18:04
Also, did you put the kiosksession file? It's missing in 10.04

ssh would help there. But, about the kiosksession file? ^
18:05
<_UsUrPeR_>
ok, it looks like the error is "Waiting for X server to shut down"
18:06
<alkisg>
kiosksession?
18:06* _UsUrPeR_ checks that
18:06
<alkisg>
It's written in the bug report about the kiosk problem
18:08
ls /opt/ltsp/i386/usr/share/ltsp/kioskSession
18:08
https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/572974
18:09
<_UsUrPeR_>
got it
18:09
one second
18:19
alkisg: in that bug, is #7's notes required for non-fatclient installations?
18:20
I am still having the same issue after copying kioskSession in to /opt/ltap/i386/usr/share/ltsp/ and updating the image
18:21
<alkisg>
The kiosk mode is a special mode, different to both thin and fat clients
18:21
So everything on that bug report is about the kiosk mode
18:21
So yeah, #7 mentions of one possible way to workaround the X_ARGS problem
18:21
<_UsUrPeR_>
so creating a XS90-disassembleXorgConf script in screen-session.d is also required?
18:21
<alkisg>
You chose another one though, to comment X_ARGS out
18:22
<_UsUrPeR_>
gotcha
18:22
and that file appears correct?
18:22
<alkisg>
So no need to do both workarounds. One of them suffices
18:22
Unsetting X_CONF sounds better than commenting out X_ARGS
18:23
<_UsUrPeR_>
ok, I am trying to figure out what the problem is then. The kioskuser user exists in the chroot, /usr/bin/google-chrome exists in the chroot...
18:23
<alkisg>
So I'd prefer that workaround. But, a better method would be to solve the problem
18:23
<_UsUrPeR_>
I agree :)
18:23
<alkisg>
I.e. see what sets X_CONF :)
18:24
<nubae>
sorry been ignoring this channel,a bit, work and other tbings...
18:24
<_UsUrPeR_>
also, I did set +x for kioskSession
18:24
<alkisg>
What's the error now?
18:24
<nubae>
alkisg, u still need the logs?
18:24
<alkisg>
Hi nubae. I tried pinging you the other day, you probably weren't on the pc
18:24
I imagine it'd be better if all the logs were there in one place
18:25
<_UsUrPeR_>
the error is... "waiting for x server to shut down" still
18:25
<nubae>
if it was sat or sun... unlikely
18:25
<alkisg>
So yeah if you could mail either me or Hyperbyte the last year's logs...
18:25
It was the day when you pinged me and you told me we'd talk later :)
18:25
<nubae>
dcc chat alkigs
18:25
<alkisg>
I'm on vacations now, I can't stay online for long
18:25
If mailing is hard, maybe scp then?
18:25
<nubae>
ah but u can l
18:26
<_UsUrPeR_>
in kioskSession, it's saying "line 1: newline unexpected"
18:26
<nubae>
do a quic scp right?
18:26
<alkisg>
I believe so
18:26
Let's go private
18:26
<nubae>
i justndid
18:26
dcc chatted u
18:26
more private
18:26
accept the connect
18:27
<alkisg>
I don't see any requests in pidgi
18:27
n
18:27
But I did /query you, I'm talking to you on the other tab...
18:27
<nubae>
ok do /dcc chat nubae from pidgin
18:28
and if not then xchat please
18:28
<alkisg>
"unknown command"
18:28
Erm... couldn't you just email me the pass? alkisg at gmail...
18:28
<nubae>
dcc chat makes a direct connection between host and user
18:28
no
18:29
<alkisg>
Sorry, installing xchat seems to much for me :-/
18:29
<nubae>
this is a server with many things on it
18:29
i trust u
18:29
<alkisg>
I can make a script that would grab them from your site, if you prefer
18:29
<nubae>
i dont trust the net
18:29
u still neeed my details
18:29
i want to give those to u via dcc
18:29
<alkisg>
If you change the pass after 1 minute, how can one exploit it?
18:30
<nubae>
and irc program will work
18:30
its standard
18:30
<alkisg>
I have irssi installed too, except for pidgin
18:30
Would that work for you?
18:30
<nubae>
umihgt learn something?
18:30
yes
18:30
<alkisg>
Or is xchat specifically needed?

Certain terminals would not let certain users login from them. for example user A will not be able to login from Machine 1 but will be able to login from Machine 2

Any idea why this could happen?

19:49
<Hyperbyte>
Heheh, it worked though.
19:49
<shan>
True ;)
19:49
<Hyperbyte>
Or do you mean 'not really subtle'? ;-)
19:50
<shan>
so any idea on how I could resolve the login problem or the date and time problem?
19:50
<Hyperbyte>
Login problem I have no idea. LTSP uses SSH as a backend for logging in though.
19:51Trixboxer has left IRC (Trixboxer!~Trixboxer@office.supportdepartment.net, Quit: "Achievement is not the end, its the beginning of new journey !!!")
19:51
<Hyperbyte>
So that's what you should test for... SSH problems.
19:51
<shan>
ok
19:51
for the date and time issue?
19:51
<abeehc>
you need the time to be correct in any case
19:51
do you have lts.conf yet?
19:51
<Hyperbyte>
You could enable a screen_02 on the clients, then when someone can't log in, you can use 'ssh username@server' to see some more info maybe
19:51
!screen_02 | echo shan
19:51
<ltsp>
shan screen_02: to get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using%20a%20shell%20SCREEN.
19:52
<Hyperbyte>
As for time, that's done by setting up ntpd on the terminal server and TIMESERVER=<server ip> in lts.conf
19:53
<shan>
ok, got it.
19:53
<Hyperbyte>
As abeehc suggested, start with the time problem first. It might be related to the login problem.
19:53
<shan>
yes, I have the default lts.conf
19:54
i haven't modified it.
19:55
<abeehc>
by default it doesn't exist
19:55
so that's a bad start i guess
19:55
<Hyperbyte>
abeehc, are you sure?
19:55
I had one.
19:56
<abeehc>
hmm
19:56
<Hyperbyte>
With lots of example config in there too.
19:56
<abeehc>
i'm sure for ubuntu 9.04 and 10.04
19:56
it doesn't go to the right place
19:56
<Hyperbyte>
Well, 'lots'... some. :)
19:56
<abeehc>
where it would be read
19:56
<shan>
it was in the /var/lib/tftpboot/...
19:56
its that the right place
19:57
<abeehc>
yep depending on your arch
19:57
/var/lib/tftpboot/ltsp/i386/lts.conf
19:57
you should set TIME_SERVER there
19:57
and TIMEZONE
19:57
<shan>
ok
19:58
<Hyperbyte>
According to man lts.conf it's TIMESERVER?
19:58dlezcano has joined IRC (dlezcano!~dlezcano@AToulouse-159-1-21-149.w92-134.abo.wanadoo.fr)
19:58
<shan>
can I set it to any of the public time servers or should it be set to the ltsp server ip address?
19:59
<Hyperbyte>
shan, you can use a public server, but imagine a whole bunch of clients from your IP querying the timeserver... it's a waste of bandwith, but the timeserver might not like it either.
19:59
Besides, setting up ntpd is easy. apt-get install ntp
19:59
<shan>
I understand
19:59
<Hyperbyte>
Then edit /etc/ntp.conf and set ntpd to start on boot
19:59
<shan>
ok
19:59
<Hyperbyte>
(I think it starts by default on boot, so you might not need to change that)
20:00
You need to put something like restrict 192.168.0.0 mask 255.255.255.0 in /etc/ntp.conf to allow your clients to query the timeserver.
20:01
<shan>
ok
20:02

yeah nbo underscore sorry dunno where i got that
20:03

sure other login options

like rdp

Also is ldm the default desktop manager or should it be changed to gdm?
20:12

ldm

do not change it

unless u enjoy pain

20:12
<shan>
ok
20:12
<Hyperbyte>
shan, and what do you mean with RCFILE_01? What do you want to know about it?
20:13
<shan>
does the ntp issues have anything to do with the login problem?
20:13
<nubae>
welll u can have different methods of logging in, be it screen, rdp, etc
20:13
<Hyperbyte>
Could be. Did you get NTP working?
20:13
<nubae>
or even mass scripts
20:14

I have put in the configuration and restarted the ntp service.
20:14

Did you set TIMEZONE and TIMESERVER in lts.conf?
20:15
<shan>
i have only put the TIMESERVER not the TIMEZONE
20:15
<abeehc>
once you have that local shell you should look at /var/log/ldm.log on a client that is not working

you ahven't even said what happens when it fails
20:16
so we are just wildly guessing

give me a minute, i will try to boot up one of the clients and see what happens
20:16
<abeehc>
and that's not great use of time
20:16
thanks
20:16
<shan>
when it fails it just comes back to the login screen
20:16
<abeehc>
gotcha, ldm.log is wortha look then once you have that shell on the local client
20:16
i think it might say exactly what's up.. if not, then the server's auth.log will be worth looking at too

Damianos, you sir, are very welcome. :)
20:48
Did you get everything working?
20:49
shan, yes, remember the client is just a Linux machine too. It boots, loads a kernel, has a syslogger and everything. It also runs a bunch of software, but only the software that is needed for a remote connection to the terminal server. So the client has it's own local logs, totally seperate from the server.
20:51
<Damianos>
Yeah, I took everything out of /etc/network/interafces except the loopback stuff and did everything via NetworkManager .... the last hangup I had was putting the wrong ipaddress for eth0 (put in the real ip address instead of 0.0.0.0)....anyway, thin clients are booting just fine and WAN and LAN are bridged real nice
20:51

when I try to go to the terminal I get a message mode not supported

When I start up the client machine, and check the terminals by pressing crtl+alt+f2 I get a root login, but when I try to login using the login screen and the try to go back to the terminal I get the mode not supported error on the screen and I am not able to proceed further on that screen.
20:57
<Hyperbyte>
shan, why are you setting X_MODE?
20:58
<shan>
because the default mode is assumed as 13xx x xxxx where as the monitor supports only 1024 x 768
20:59
when I login to the terminal using a different user, i am able to view the desktop..
21:02
could that the problem, the default login resolution for all the users may be set to the higher resolution. For the user that I am able to get to the desktop, i had changed the monitio settings after loging in to 1024 x 768, but for the other users I did not do that/
21:02alkisg has joined IRC (alkisg!~alkisg@ubuntu/member/alkisg)
21:03
<shan>
Is there a config file where I could set the default resolution for all the users?
21:04
<alkisg>
XRANDR_MODE_0 in lts.conf
21:04
!lts.conf

Hey Alkis. :)
21:11
<alkisg>
Yo :)
21:11
<Hyperbyte>
I ended up buying new CPU + RAM as well.. heh.
21:11
My old ones were incompatible with the new motherboard.
21:12
<alkisg>
Haha
21:12
<Hyperbyte>
So anytime you have a few hundred users that need some server to work on, send 'em over. :)
21:12
<alkisg>
In the middle of crisis... you go ahead and replace the whole server? :D
21:12
Time to look for bonding now, eh?
21:13
<Hyperbyte>
Tomorrow.
21:13
<markit>
alkisg: I've booted with systemrescue cd just to try to troubleshooting the bonding problem
21:13
<Hyperbyte>
Well actually I've started working 10, 11 hours a day to keep ahead of the workload. :)
21:13
<markit>
to make it short... is a switch problem!
21:14
at least, I changed the 1Gb 8 port with an older 100Mbs 8 port and now everything works fine
21:14
<Hyperbyte>
So that solves my crisis problems. And since I'm going to the tranquility of Norway in a week or two, I don't wear myself out -too- much.
21:14
<markit>
both nic on the server have light on, and not strange "flashes" of all the ports all the time
21:15

she teaches elementary school music and is in a wheelchair....it would be a real blessing if she didn't have to physically go to every machine to do things
21:19
<shan>
rc_files: /bin/sh /usr/share/ldm/ldm-script xsession
21:19
<alkisg>
shan: your problem is that you cannot login, or that X crashes?
21:19
Also, don't paste all that stuff here
21:19
Use the pastebin
21:19
<shan>
ldm_spawn: pid = 2964
21:19
<alkisg>
Now you're just destroying other people's conversation
21:20
<Damianos>
I'm busting my ass to get it done before the kids start showing up next week
21:20
<alkisg>
Damianos: there are 2 ways to install italc. The easy one is: `sudo apt-get install italc-master`, on the server. No keys or anything else needed this way.
21:21
<shan>
I am sorry, I am not able to do that as I am not able to login to the terminal to use the mouse to copy the output of the file to pastbin.
21:21
<markit>
Damianos: I see. I'm setting up a server for elementary schools also.. I need it because teachers tell me that they need to show theri desktop to every children, and then "monitor" how they do it theirselves without being there
21:21
<alkisg>
For the other way with the keys, check the ubuntultsp wiki, there's some information there
21:21
shan: you're typing it here, right? Type it into the pastebin.
21:21
<shan>
ok,got it.
21:21
<alkisg>
Now even if one wanted to read what you're typing, he can't
21:21
<shan>
I will do that.
21:21
<markit>
Damianos: where are you from? (here northern Iùtaly)
21:21
Italy
21:21
<alkisg>
shan: but, again: is your problem that you cannot login, or that X crashes?
21:22
<shan>
I am not able to login using certain users.
21:22
<alkisg>
Because if the problem is that X crashes, usually it's caused by compiz
21:22
That sounds like compiz too.
21:22
!compiz
21:22
<ltsp>
alkisg: compiz: (#1) The default window manager in Gnome is gnome-wm, which automatically launches compiz if it thinks that the card supports it. This causes some LTSP clients to hang just after logon. To disable compiz, see: !disable-compiz, or (#2) the default window manager in gnome is gnome-wm, which automatically chooses compiz if it thinks that the card supports it. Compiz is causing login problems to some clients (1 more message)
21:22
<shan>
On the same client, I am able to login as a different user.
21:22
<alkisg>
!disable-compiz | echo shan:
21:22
<ltsp>
shan: disable-compiz: To disable compiz for all users, run: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity.
21:23
<alkisg>
shan, try that command on the server. Then try again to login as the user that had the problem.
21:23
That command is reversible, so you can undo it if you want
21:23
<shan>
ok
21:23
<Damianos>
alkisg: how can I uninstall it? I've been through the wiki and various articles...I do the whole ica -createkeypairs thing as well as made sure the keys permissions were set correctly
21:24
I'm afraid my nvidia driver did something to it
21:24
I was trying to set up dual screens when italc stopped seeing the clients
21:24
markit: I'm in Tennessee USA
21:25
<markit>
Damianos: ok, too far to meet, and can't talk in italian I guess, lol
21:25
<alkisg>
Damianos: sudo apt-get purge italc-master italc-client libitalc; rm -rf /etc/italc ==> or something similar, please check before running those, I haven't used italc for 2 years
21:25
<Damianos>
No...I'm of Greek heritage
21:25
<markit>
Damianos: I'm really interested if you can make italc work decently.. what distro? here kubuntu 11.04+backports
21:25
<Damianos>
alkisg: thanks
21:26
<markit>
Damianos: so you could translate alkisg's software in english?
21:26
<Damianos>
markit: everything else is going great here. I installed docky and it works fantastic with just the metacity composite manager
21:27
markit: I actually speak Hungarian a lot better than I do Greek.
21:28
<markit>
Damianos: do you mind if I give you my email to tell me your experience about italc and how make it work?
21:28
<Damianos>
markit: Oh and I chose to go with Ubuntu 10.0.4 LTS
21:28
markit: no not at all. I'd be happy to help any way I could
21:29
<Hyperbyte>
Damianos++;
21:29
Happy to help others! You are now a 1-star LTSP user!
21:30
<Damianos>
Actually, I'm hoping to update my web site with a blog about my adventures
21:30
<markit>
Damianos: thanks, I've wrote my email in a private chat
21:30
Damianos: how is that you wife's school is switching to Free software?
21:31
<alkisg>
Can someone with Ubuntu Natty (11.04) pastebin that file? /etc/X11/Xsession.d/65compiz_profile-on-session

<Damianos>
markit: they're not. The IT department is fighting and questioning this every step of the way. I'm providing my own desktop and all I asked for is a switch and they're givving me grief
21:32
to hell with them though, this is for my wife and it's made of tech that I saved from the dumpster
21:33
their dumpster to be precise
21:33
<shan>
alkisg: Hyperbyte: I guess it is working now. I will have to wait until tomorrow morning, when all the users will be in office to check it out throughly.
21:33
Thank you guys for all the support you had give me today.
21:34
<alkisg>
You're welcome
21:34
Remember to use XRANDR_MODE_0 instead of X_MODE_0
21:34
<shan>
I sure will.
21:34
<markit>
Damianos: mmm FOSS has low acceptance here too... and money are wasted to proprietary sw, but never invested in FOSS.

21:35
<alkisg>
Good night from me too. :)
21:35
<markit>
because thin clients are not very good for animations... and elementary school could need it a lot
21:35alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Quit: Leaving.)
21:35
<markit>
alkisg: good night
21:35
<Damianos>
setting up thin clients
21:36
good night alkisg
21:36
her basic needs are internet and some midi related programs so thin clients work great
21:37
well thin clients aren't as bad as most people think. If you have a good GPU on the server and a fast switch I think it could be useable
21:37
<markit>
ok :)
21:38
GPU on the server is useless
21:38
the rendering is done by clients
21:38
X-server is run on clients PC
21:38
and depends also upon the number of pc :) (I've 12)
21:39
<Damianos>
she has 8 stations
21:39
<markit>
I hope thin is enough, if not I will go to fat, fortunately they have 1GB ram
21:39
<Damianos>
wow
21:39
my thins have 128MB
21:40
oh sorry, you meant for the GPU
21:40
<markit>
well, mine are "real" pc formely poisoned by M$ XP
21:40
no, 1GB ram
21:40
<Damianos>
ok
21:40
<markit>
and a not very performing video board, onfortunately (sys something)
21:41
teachers are very unhappy about the change, I convinced them but if things work not very good, they will scream a lot
21:41
<Damianos>
well let me ask you this...can you still use the GPU with thin clients or is that fat only?
21:41
<markit>
I suppose you can, since X-Window server runs on clients
21:41
<Damianos>
interesting
21:41
<markit>
with X the "client server" is "upside down"
21:42
X-Server is what is rendering locally, the client is the application window
21:42
(that runs on your ltsp server)
21:43
<Damianos>
so the X windowing system is in vmlinuz?
21:43
in the initrd image?
21:43
<markit>
yes
21:43
<Damianos>
ok...so it's basically just doing ssh with x-forwarding
21:43
<markit>
ltsp provides a very basic linux+gnu+X-Window environment run by "clients"
21:44
probably, the guru is alkisg :)
21:44
<Damianos>
yeah, he is the man
21:44
saved me after hours of grief
21:45
<markit>
btw, if you need more bandwidth you can add an interface to the server and use bonding, I'm experimenting right now with it
21:45
but I've used an old switch that is broken (or has a broken firmware) and wasted a lot of time
21:45
changing switch solved everything
21:45
(when you say luck...)
21:46
<Damianos>
I think it will be ok, it's just that the switch I have now is only 8 ports and that is not enough for 8 stations
21:46
<markit>
also I've the problem that if the teacher logoff the server, the screen becomes black and never goes on again
21:46
<Damianos>
hmm
21:46
<markit>
so you figure how happy I am of the situation
21:46
<Damianos>
ouch
21:47
<markit>
"GNU is very stable" -> black screen at logout
21:47
<Damianos>
I am making sure I experiment with a vm for thin client before I roll out at school
21:47
<markit>
the problem with FOSS is that you have to justify every fault
21:47
while with M$crap "is normal"
21:48
well, with my first deploy I encountered problems that I faced only with real hardware
21:48
i.e. very difficoult boot of clients
21:49
(a rare circustamce when you have 100Mbs clients and a 1Gbit switch, fortunalty alkisg had the patch)
21:49
or clients with the logout menu item "suspend" that acted upon the SERVER
21:49
and was not easy to remove
21:50
<Damianos>
well I look at it this way...I use everything and for my personal use I like Macs. OSX is a great example of what can be accomplished with OSS. They just put a very polished desktop on top of a Unix core. There is no reason why Linux, BSD or any other 'Nix can't be as good if not better when you know what you're doing
21:50
<markit>
or server video board too limited for the monitor... and not having a decent pc-express slot
21:50
OSX is not FOSS, is one of the most slavery creations on sw :)
21:51
<Damianos>
OSX is a hybrid though...the foundation is completely open source
21:51
<markit>
yea, but you do nothing with it
21:51
or do you use it only command line? :)
21:52
my focal point is freedom, technical aspect are secondary
21:52
<Damianos>
I use it for music and I like to use any linux tricks I learn on it
21:52
<markit>
are you expert of voice recording?
21:53
I'm providing, with my wife, italian voices for Asterisk
21:53
<Damianos>
I play stringed instruments...guitar and greek bouzouki
21:53
<markit>
let me check bouzouki on wikipedia :)
21:53
<Damianos>
nice....Asterisk as in the animated film?
21:53
<markit>
no, like *
21:54
<Damianos>
oh
21:54
<markit>
the other is AsteriX
21:54
http://www.asterisk.org/
21:54
is a PBX
21:54
and voices are "you dialed the wrong number"
21:55
or something like that PBX plays when needed
21:55
<Damianos>
yes I remember now...great for PBX and VOIP too right?
21:55
<markit>
right
21:55
<Damianos>
gotcha

I'm going to buy some new hw for recording the new ones
21:56
<Damianos>
cool
21:56
recording is a money pit
21:56
lol
21:56
<markit>
but I'm not expert, and also is hard to check if some piece works with GNU/Linux
21:57
<Damianos>
use a standalone recorder and then bring the audio files in via flash drive
21:57
I bet you have an android phone
21:57
<markit>
yea... I want to buy a mixer + mic + usb audio board = 143 euros :(
21:57
<Damianos>
get an android app with a four track recorder on it
21:57
<markit>
yes, G1, the first one... not happy about licenses of most of the apps though... but is the "less evil" I've found
21:57
<Damianos>
then use whatever mic you like
21:58
<markit>
how can I connect mic with android?
21:58
well, better go private
21:58
not very much ltsp related :)
21:58
<Damianos>
true
21:58
actually, I have to go meet a client in a bit so I should start packing my stuff
21:59
<markit>
ok, no problem :)
22:00
see you later or better tomorrow
22:00
(11.59pm here)
22:00

ok...nice meeting you markit
