Is there way to remote reboot client when no one logged in?

00:15
<alkisg>
With a stock ltsp installation, no
00:16
<muppis>
bummer.
00:16
<alkisg>
There are ways to do it. Cron jobs, italc, etc
00:16
daemons listening for commands, ssh etc
00:16
<gnunux>
hi
00:16
<muppis>
I'm aware of those, just wondering could be some trick to do get it rebooted.
00:17
<alkisg>
If it's logged on, then sure. But if it's not logged on, no.
00:17
Hi gnunux
00:18
<muppis>
Then has try get someone do it manually.

O_o

<alkisg>
?
00:38
<muppis>
local_apps_menu_items doesn't work..
00:38
<alkisg>
That's used to *limit* which localapps are shown
00:39
If unset, all of them show in the menus
00:40
<muppis>
Ok.
00:41
<alkisg>
Of course you do need LOCAL_APPS=True
00:42
<muppis>
Yes, Yes, and set LOCAL_APPS_MENU also.
00:44
<alkisg>
Haha sorry you don't need LOCAL_APPS=True, just the LOCAL_APPS_MENU
00:44
I was looking at the man page and it's wrong
00:44
First, it says:
00:44
LOCAL_APPS
00:44
boolean default False
00:44
Whether to run apps locally on the client or not
00:44
A little below it says:
00:45
LOCAL_APPS
00:45
boolean, default True
00:45
Enables support for running local apps on the thin client.
00:45
The second is the correct one ;)
00:54
<muppis>
Can be lts.conf reloaded without rebooting?
00:54
Or it is done by ldm?
00:59
<alkisg>
Client reboot is required
01:08
<muppis>
Just can't get it working.
01:08
<alkisg>
Try: ltsp-localapps xterm
01:08
Does it pop up an xterm?
01:09
<muppis>
Sure, and ltsp-localapps google-earth works also.
01:09
<alkisg>
The problem is that they don't show up in the menus?
01:09
<muppis>
Yep.
01:09
<alkisg>
From the local xterm, try: getltscfg -a
01:09
And pastebin the output
01:10
<muppis>
Permission denied.
01:10
<alkisg>
Where?
01:11
<muppis>
http://pastebin.com/wh3EGreq
01:11
<alkisg>
That's not normal
01:11
Which distro/version is that?
01:12
<muppis>
Still 10.04 ;)
01:12
<alkisg>
Did you do anything weird with lts.conf?
01:12
On the server, try: ls -l /opt/ltsp/i386/etc/lts.conf
01:12
<muppis>
Read/write only for root.
01:13
<alkisg>
$ ls -l /opt/ltsp/i386/etc/lts.conf
01:13
-rw-r--r-- 1 root root 765 2011-03-21 16:48 /opt/ltsp/i386/etc/lts.conf
01:13
^ that's the correct mode
01:13
Fix it + ltsp-update-image
01:14
Or you did that on purpose?
01:14
<muppis>
Nope. Had a lot permission issues since image rebuild.
01:14
<alkisg>
I wonder why...
01:14
<muppis>
So do I.
01:15
Like lts.conf under tftboot had it.
01:15
Just like this one under chroot.
01:15
<alkisg>
Check your umask
01:15
Or the roots umask
01:16
<muppis>
Also kernelfiles under tftboot was unreadable by tfpd and caused booting problems.
01:16
*tftpd
01:16
<alkisg>
If lts.conf in tftp is only readable by root, then tftpd-hpa won't be able to read it
01:16
You're sure you didn't upgrade your kernels or ltsp version to something more recent, right?
01:16
From any ppas or manual compile...
01:16
<muppis>
I noticed, caused printing problems with usb printers in clients.
01:17
Used ltsp-update-kernels..
01:18
<alkisg>
No I mean you didn't install kernel 2.6.38 or anything similar... the new kernels change the permissions
01:20dobber (~dobber@89.190.197.77) joined #ltsp.
01:24
<muppis>
I can't surely say, but haven't by purposly.
01:24
<alkisg>
ls -l /opt/ltsp/i386/boot
01:26
<muppis>
2.6.32-30-generic
01:27
<alkisg>
That's the old lucid kernel, you're ok
01:27
Check your umask
01:28
(by running: umask)
01:28
<muppis>
0077
01:28
<alkisg>
That's the problem
01:28
The default is 0022
01:28
<muppis>
Njam.
01:28
<alkisg>
So that umask propagates to ltsp-update-kernels etc
01:28
Maybe there's a bug somewhere there
01:28
<muppis>
umask 0022 fixes?
01:29
<alkisg>
Maybe
01:29
<muppis>
Atleast shows it as 0022 after that.
01:29
<alkisg>
How did you change your umask?
01:29
Maybe the problem isn't *your* umask, but the root's umask
01:30
<muppis>
Done it as root.
01:30
<alkisg>
Where?
01:30
<muppis>
At server.
01:30
<alkisg>
At which startup script?
01:30
How did you modify your default umask? You must have put it in a script
01:31
When I boot my pc I have umask=0022. When you boot your pc you have umask=0077. What did you change to get that? That's what I'm asking
01:32
<muppis>
Funny.. It is as 022 in /etc/profile, which should loaded in every login.
01:33
<alkisg>
See the docs for umask in /etc/login.defs
01:39
<muppis>
Hmm..

04:27
<alkisg>
muppis: so now `getltscfg -a` works fine?
04:27
<muppis>
alkisg, yes.
04:28
<alkisg>
And you get a "localapps" menu for acroread and vlc, but you don't get one for firefox?
04:29
<muppis>
Yes. And as I removed _items -setting from lts.conf, also ltsp-cluster-info shoed up to menu.
04:29
*showed
04:29
<alkisg>
Can you put the output of getltscfg -a to pastebin?
04:30* muppis hops to other pc...
04:31
<muppis>
http://pastebin.com/68kAQ4dC
04:34
<alkisg>
You only removed DNS_SERVER? Ok, looks good
04:35
Now, on a thin client, on a regular gnome-terminal. *not* on a local xterm:
04:35
echo $XDG_DATA_DIRS
04:36
<muppis>
/usr/share/gnome:/tmp/ltsp-localapps-<user-removed>/:/usr/local/share/:/usr/share/
04:36
<alkisg>
Good. Now, `ls -l /tmp/ltsp-localapps-<user-removed>`
04:36
Is firefox there?
04:37
<muppis>
It's under applications -dir.
04:37
<alkisg>
Well, then that's the one that is on your menus
04:37
<muppis>
As well acroread, vlc and others.
04:37
<alkisg>
Try it. Go to the firefox menu, and *drag* it to your desktop
04:38
Then, in your desktop dir, do: `cat firefox.desktop`
04:38
And see if it calls ltsp-localapps
04:38
<andygraybeal>
morning!
04:38
<muppis>
Nope, it calls directly firefox.
04:39
As file under tmp calls xprop.
04:39
<alkisg>
muppis: something doesn't make sense
04:39
andygraybeal: hello
04:39
<muppis>
I've noticed..
04:39
<andygraybeal>
alkisg, :))))
04:40
<alkisg>
muppis: the gnome menus get their data from XDG_DATA_DIRS. And you say that, well, they don't
04:40
You don't happen to have an "applications" dir in /usr/share/gnome, right?
04:41
<muppis>
Nope.
04:41
<alkisg>
I don't know what goes wrong. Wanna vnc?
04:42
<muppis>
Why not.
04:42
<alkisg>
x11vnc -connect alkisg.dyndns.org
04:42
From the thin client
04:43
<muppis>
Be my guest.
04:48
<alkisg>
muppis: ok, left vnc
04:48
You have customized menus for that user
04:48
Those override the ltsp generated ones
04:48
Remove the .local/share/applications folder
04:48
<muppis>
Ok.

if i install LTSP on a 11.04 box, will my clients get Unity as their interface? I'm wanting to see how it performs.
05:45
<brunolambert>
robehend11: sure
05:45
<robehend11>
ah, cool. guess i have a weekend project
05:45bobby_C (~bobby@85-124-22-227.teleworker.xdsl-line.inode.at) joined #ltsp.
05:46
<brunolambert>
if you get the edubuntu version of it, you can install LTSP at installation time by checking a box
05:47
<robehend11>
if i'm not mistaken, the Edubuntu 11.04 doesnt include unity.
05:50
<andygraybeal>
how do i get the localapps (like firefox) to have the 'ubuntu look and feel' and not just the 'xwindows' feel?
05:52
<robehend11>
if i'm not mistaken, thats the gtk themeing, correct?
05:53
<muppis>
Looks like it.
05:53
<robehend11>
so you'd have to throw the whole gtk setup into a localapp as well, I'm guessing. Unless it could be tied into ltsp-remoteapps somehow..
05:54
<andygraybeal>
aah
05:54
so gtk theming is huge?
05:55
and probably a bad thing if i do install it?
05:59
<robehend11>
andygraybeal: no idea, actually. never really minded enough to find out haha
06:00
generally though, less you put in the chroot, faster it runs, as its loading less over the network
06:01
<andygraybeal>
robehend11, awesome thank you sounds good.
06:01
<robehend11>
no problem.

wow. i'm surprised how quick unity is running on an old celeron with 512 megs of ram. Impressive
06:26
<alkisg>
As a thin client?
06:27
<robehend11>
oh, not yet. Thats the next step. I wanted to make sure it would be usual on a stand-alone first ;)
06:27
<alkisg>
I found it slower than old gnome on my daughters atom/1g ram
06:27
<robehend11>
i'm noticing slower boot times, but after I'm in, it seems pretty responsive
06:28
<alkisg>
I liked the extra screen space though
06:28
<robehend11>
agreed. I also like how it auto-fullscreens and gets out of the way
06:31
though i do wish it would let me get rid of the Applications and Menu switcher launchers. I'm getting this setup for preschool, and they click EVERYTHING
06:32
<alkisg>
Yeah it needs much policing. I don't care for the workspace switcher myself, never understood the meaning of multiple workspaces (yet with the same desktop icons)
06:33
<andygraybeal>
so cute :) (preschoolers clicking @ everything!)
06:33
<robehend11>
I use multiple workspaces only when I dont have multiple monitors.
06:33
andygraybeal: tell that to how many mice they go through. It's amazing.
06:34
<andygraybeal>
i used to work at a prison system (several prisons) before optical mice... the inmates would always steal the balls.. and supposedly smoke them.. but i never believed who told me this.
06:34
<alkisg>
robehend11: how do you use them? You put firefox/evolution on one of them, and e.g. openoffice/gedit on the other? It seems to me that would take lots of clicks and organization with little to gain (I always use maximized windows anyway)
06:34
Smoke the mouse balls?!!!!
06:35
<andygraybeal>
yes, someone told me that, i think he was puling my leg, i was 19
06:36
<robehend11>
alkisg: depends on what i'm doing. But ya, text editor on one, firefox on another. or 2 firefox windows, if for some reason i dont want to sue tabs.
06:36
alkisg: finally got rid of mouse balls. No longer will I have them flying around the labs :D
06:36
<andygraybeal>
robehend11, yes, the invention of optical mice is awesome.
06:37* alkisg had serial mice up until 2 years ago
06:37
<robehend11>
so did we :(
06:37
<andygraybeal>
no cleaning the little rollers either
06:37
<robehend11>
we've updated now to PS2 Opticals! wooo
06:37
<andygraybeal>
:)
06:38
<robehend11>
though I did find that our kindergarten decided to see what was inside one of them, and based it open with a snow boot

hmm. well thats odd. Have you tried the old standby of just rebooting the server, see if DHCP cleans itself up?
06:40
<alkisg>
That warning isn't something significant. distro/version?
06:41

<alkisg>
Does he see something on the client, above the initramfs prompt?
06:42
E.g. complains about nbd?
06:42
<nosedrum>
i tell him...
06:42
target filesystem doesn't have /bin/init
06:43
and
06:43
Non initramfs try passing init=bootarg
06:43
and many message with mounting fail

<alkisg>
9.04 is the old ubuntu version, jaunty, right? Not 10.04...
06:44
<nosedrum>
yes
06:44
<alkisg>
And you say there were no updates, no calls to ltsp-update-image etc, correct?
06:44
<nosedrum>
upgrade of our 80 servers in few weeks
06:44
but this server works since two years
06:44
but he say he never reboot the client
06:44
always on logon screen
06:45
<alkisg>
Ah. So it might have broken months ago?
06:45
<nosedrum>
i don"t really know ....
06:45
<alkisg>
OK

yes busybox
06:45

So there was a call to ltsp-update-image
06:46

On the client, tell him to try:
06:46
nbd-client 1.2.3.4 2000 /dev/nbd0

Maybe there's another dhcp server on his network, giving broken ip addresses
06:50
<robehend11>
nah, he saw the request and offer in syslog for that mac address
06:50
<alkisg>
Tell him to run: ipconfig -n eth0
06:51
robehend11: that's the pxe requrest
06:51
Not the ipconfig request
06:51
<nosedrum>
i ask people about a guy who plug wifi routeur or somethin
06:52
<alkisg>
And check the output of ipconfig, if the subnet is the one of the ltsp server or not
06:52
<nosedrum>
who can i find another dhcp ???
06:53
<alkisg>
nosedrum: here's an easy way to verify if that's the problem or not
06:53
Tell him to run:
06:53
sudo gedit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
06:53
<nosedrum>
i have ssh on server
06:53

Ah nice
06:53

IPAPPEND 3
06:53
On a new line
06:53
Save, and tell him to reboot the client

OK, now here's how to find the rogue dhcp server
06:56
On your server, run: sudo ipconfig -n /usr/lib/klibc/bin/ipconfig
06:56
<robehend11>
and smack whoever brought it in >:D
06:56
<alkisg>
It will request a dhcp address but will not assign it to the card
06:56
Sorry
06:56
Wrong command
06:56
sudo /usr/lib/klibc/bin/ipconfig -n eth0
06:57

do you guys run evolution as a localapp?
06:59
<nosedrum>
possible
06:59
<robehend11>
nope. I've moved em all to webmail
06:59
<andygraybeal>
robehend11, tell me why? what about calendar ?
06:59
<robehend11>
andygraybeal: becuase Google Apps is free for education :D
07:00* alkisg uses evolution to see his gmail + google calendar etc :D
07:00
<robehend11>
;)
07:00
I just went with webmail, cuz then students/staff will remember how to get there out of the office, mostly
07:00
<alkisg>
Evolution requires gconf, I think apps that need gconf don't play well as localapps
07:00
<robehend11>
easy enough to tell em to go to mail.xxxxx.com, regardless of where they are ;)
07:01

07:07
<nosedrum>
sure alkisg
07:07
have you more explanation about IPAPPEND 3 ? i'm curoious and not understand this totaly
07:08
<alkisg>
It instructs pxelinux to pass the IP it got in the pxe stage as a kernel parameter
07:08
Then the initramfs reuses the pxe ip, instead of asking for a new one
07:08
<nosedrum>
nice !
07:08
<alkisg>
In the pxe stage, your clients ignore the rogue offers, because those don't have a boot filename
07:08
<nosedrum>
thx for all ! you really rocks guys !
07:09

So with ipappend 3 it works even with rogue dhcp servers. But sure it's good to shut them down anyway.

yea, that's not what i'm trying to do
07:50
i'm querying for the general feeling though - i guess it's basically firefox, flash... java plugin... ?
07:50
that normlaly gets run locally to conserve resources
07:51* alkisg never uses localapps, either plain thin or plain fat
07:51
<alkisg>
(on < 500 ram or > 500 PCs respectively)
07:52
<andygraybeal>
ok
07:53
i still don't quite understand the fat client.. but that's me needing to read more.
07:53
<alkisg>
Imagine all localapps
07:53
<andygraybeal>
it took me long enough to understand the thin client :)
07:54
<alkisg>
E.g. tux*, impress, google earth, flash, 3d apps, games won't play very well on thin clients
07:54
But they play fine as localapps or on fat clients
07:54
Everything that needs exceesive screen updating

Hi all. Got an interesting problem. I have several Asus EEE Box PCs that use a JMicron JMC25x ethernet card (module jme.ko). They fail to boot on Ubuntu 9.10 due to a bug in the module for that kernel. I have tried Ubuntu 10.10 and they boot, but they will crash back to a login when we try and run a remote app from another linux box (I suspect an XORG error).
09:51Ahmuck (~quietly@p178n22.ruraltel.net) joined #ltsp.
09:53
<andrew_ubuntu>
I thought about building a new kernel in the Ubuntu 9.10 chroot, but I do not know how to do this. I also thought about getting USB Ethernet adapters, but do not know if this would even work, or support pxe,etc. My only other thought was to copy the jme.ko kernel from the Ubuntu 10.10 chroot and put it in the 9.10 chroot, rebuild the image... but that failed to boot as well. Any other thoughts on how to get around this?
09:54
<robehend11>
andrew_ubuntu: Have you looked at the video card drivers? If i remember right, alot of those EEEBoxes have Ions, which need the binary driver from Nvidia to do their job right
09:55
That was the fix for my Acer Aspire Revo boxes, which are quite similiar, at least
09:55
<andrew_ubuntu>
these are Intel, which I specifically made sure they had because of all the problems I've had with ATI/Nvidia.
09:55
<robehend11>
ah, nvm then ;)
09:57
<andrew_ubuntu>
And, as far as the remote app that we run, I evoke that using SSH, but I cannot find any specific errors as to why it crashes the desktop.
09:57
<robehend11>
weird. I've only had drivers for nics either work great or not at all. :(
09:57
ooo, luch, bbl
09:57
lunch*
09:57
<alkisg>
andrew_ubuntu: which intels? 8xx?
09:58
<andrew_ubuntu>
My only other option is to try OpenSuSE or Fedora...
09:58
<alkisg>
lspci -nn -k | grep -A 2 VGA
09:58
<andrew_ubuntu>
let me check the video card...
10:00
the odd thing is, my server is Ubuntu 9.10, so I got the bright idea that I would just build a Ubuntu 10.10 chroot and NOT change the server....this will boot those boxes, but they still crash when I run that in-house app. So, it obviously has something to do with the chroot, not the server.
10:01
The video card is Intel 945GME (rev 03)
10:03
Does anyone have experience with USB Ethernet adapters? I didn't even think of trying that until today.
10:05
these boxes do have wireless ethernet... that is another thought, and I have read something about a way to boot via wireless (in a roundabout way).

Yup, it crashes even on a terminal w/o the JMicro NIC :(
11:43
<alkisg>
andrew_ubuntu: did those terminals *not* crash with some distro?
11:43
(or version)/
11:44
<andrew_ubuntu>
So, looks like I really only have 2 choices. Try a different Distro, or contact our software ppl and have them fix it (could potentially be lots of money which is why I haven't gone that route yet).
11:44
<alkisg>
Or it might be something simple like disabling compiz :)
11:44
(which is on by default)
11:45
<andrew_ubuntu>
alkisg: Ya, I turned off compiz. I have not tried another distro yet though... might be my next move.
11:45
<alkisg>
How did you turn off compiz?
11:45
And why are you trying 9.10 and not e.g. 10.04 which is more recent + an lts?
11:45
<andrew_ubuntu>
under appearance... selected none
11:47
I tried 10.10, had the crashing problems, so then I just went to 9.10 which I knew worked because I already have one branch using that. That is when I discovered the JMicro's don't boot. 10.04 doesn't allow the JMicros to boot either.
11:47
<alkisg>
You can easily add the jmicro module to the initramfs
11:47
It's just 1 line
11:47
And being an lts, you can also easily try the maverick or natty kernels
11:47
(those kernels are backported for lts releases)
11:48
<andrew_ubuntu>
how do you add those kernels? (I did have to add the jme.ko to the initramfs otherwise it would not detect).
11:49
<alkisg>
Here's the proper way to add the jme module: https://help.ubuntu.com/community/UbuntuLTSP/AddingModules
11:49
<andrew_ubuntu>
yup, that is the page I followed.
11:49
<alkisg>
And to add a new kernel, you just install the package, e.g. for maverick it is...
11:49
linux-image-generic-lts-backport-maverick
11:50
That always depends on the maverick kernel, so it even gets updated automatically
11:50
And linux-image-generic-lts-backport-natty for 2.6.38
11:51
Finally, when the crash happens, check xorg.log and ~/.xsession-errors for that user
11:55
<andygraybeal>
i'm going to try the fatclient setup right now :)

andygraybeal: thanks for getting things started.
14:48
Yes. vlc works well on the server and looks like it would do the best I think, but it shows a blue screen instead of the video. The audio work.
14:48
<andygraybeal>
i'm sure you made sure the right codecs are installed?
14:50

As far as I could, did all the multimedia install pages I could find in the Ubuntu wiki. Also, did more than 1 blog post. Pretty much they were just getting repetitive so that's why I think I got them all...
14:51
<andygraybeal>
sorry it's obvious, but did you check to make sure it's actually the localapps running vlc?
14:51
<dgroos>
It's weird that the mp4's were working both with stand alone player and with firefox earlier in the year, they were working flawlessly, but now don't work. Never figured out when it happened though since we didn't do video for a while.
14:52
hmmmm... obvious to one might be opaque to another ;) I'll check.

hi dlbass.. it is good. i just learned how to set up fat clients today! i'm running it in a test environment! i'm waiting on a confirmation code so i can help edit the ltsp wiki
15:01
<dlbass>
what do you mena by fat clients exactly?
15:01
<andygraybeal>
that's exactly what i said.. it took me the longest time to wrap my head around thin clients.... check this out: https://help.ubuntu.com/community/UbuntuLTSP/FatClients
15:02
the machines don't have hd's like thin clients... but they should have more memory - -and all the applications get offloaded into the clients memory space!
15:02
so it taxes the clients more, and the server less.
15:02
<dlbass>
that is awesome!
15:03
we might have to check into that.
15:03
<andygraybeal>
if all yuor machiens have >500 fat clients ar a good choice. all my boxes i got from an auction @ around $30 .. and they all have 1GB of ram.
15:03
err >500MB
15:03
yea, alkisg walked me through it today
15:04
i got an 8GB server.. and it's crammed jammed... i need some relief.. and this will be it.
15:05
<dlbass>
that's cool. We can get a lot of free computers from the local community college for free that would have 500Mb to 1Gb of ram. And with the possibilty of ripping the HDD out and throwing them into a lab it might be worth it.

I will have to tell my boss about it. How much performance increase did you get?
15:07
<andygraybeal>
i'm just testing for today - but the server is running with about 400MB of memory and the client is running firefox using 167mb of memory .... times that by however many people are using firefox by however many tabs they have open :)
15:08
yea, i'm pretty lucky... i can buy p4 machines from a local university auction w/ 1gb+ of memory in them for about $30 every quarter. there is quite a selection. i test every machine before the auction.

<dlbass>
I shall read into this fat client stuff. Currently I am trying to get my second network card to work, but it does not want to. I have one that is working for the LTSP connection, and one that I want to connect me to the internet. Fresh install of Edubuntu 10.10
15:10
<andygraybeal>
i'm conservative... 10.04 till 2015 :)
15:10
or something
15:11
<dlbass>
I might should have done that. I like natty a lot so far, so I was planning to upgrade this machine to that...
15:12
<andygraybeal>
i'll thik about it in 12.04 comes out i think that's the next ltsp
15:12
er... LTP
15:12
LTS
15:14
<dlbass>
ah
15:14
grub is also broken on this machine
15:14
It is such a turd.
15:17
well guys, I'm off, cya later!

andygraybeal: coming back to the irc...
15:43
I've been testing lots of things.
15:43
I tried to run .mov, .mp4, .flv and none work on the client. All work on the server. .flv works on firefox.
15:44
I ran a .mov locally with vlc, it didn't work, but I did open up a local term and found it WAS running locally on the client.
15:45
I just used the 'ltsp-localapps vlc' and got similar results--audio but no video.
15:45
I wasn't able to run either gxine or mplayer with ltsp-localapps. That might be interesting...
15:49
just figured I had to use 'totem' for name of movie player, it launched but wouldn't play the video. They complain about different plugins not installed.
15:50
<abeehc>
have you done ubuntu-restricted-extras?
15:51
<dgroos>
abeehc: yes, both in chroot and regular root.
15:51
<abeehc>
vlc rules nevermind anyway
15:51
i'd focus there.. vlc has a "messages' log that might be helpful
15:51
<dgroos>
(I agree!)
15:51
<abeehc>
iu'm just jumpin in; what video hardware are we talking about?
15:52
ohh, have you disabled compiz?
15:52
<dgroos>
client with onboard video. Yes I've disabled compiz.
15:53
The clients ran both locally and via firefox earlier in the year so I know the hardware works.
15:53
<abeehc>
i'd wonder what "xvinfo" says on the client
15:53
i think that's relevant notsure
15:54
<dgroos>
(trying to get back to my local terminal...)
15:56
how does one copy text from a local terminal? right clicking isn't working...

abeehc: OK, couldn't copy the text but took screen shot and pastebin-ed the image at: http://imagepaste.nullnetwork.net/viewimage.php?id=2166
16:03
<abeehc>
I think that lacks a section that my client shows lemme just see.. not sure it's the issue but who knows
16:04
have you set color depth in lts.conf?
16:04
<dgroos>
no...
16:04ogra_ (~ogra@p5098ed03.dip0.t-ipconnect.de) left irc: Excess Flood
16:05
<abeehc>
maybe do vlc -vvvvvvvv filename and paste the output?

<dgroos>
That brings me to something I've been thinking for a while, we need a repository of sort of simple, sample, lts.conf files. Would you post part of yours? I'll put it in my blog, attributed to you.
16:06
<abeehc>
mine's not that simple... the ltsp-docs package and man lts.conf is what i rely on
16:07
<dgroos>
I liked the docs though often can't decipher the man pages.
16:08
<abeehc>
the most basic would simply be http://pastebin.com/pfqD7EvW
16:08
it used to be ltsparameters.txt but then it moved into the man page. I think there are good simple examples of the bottom of the man page
16:08
i imagine more interesting samples coould become a part of ltsp-docs not sure
16:09
<dgroos>
OK, still don't know how to save output from a local xterm to my desktop... and there was too much output to do screen shots... command?

<abeehc>
well the package pastebininit makes it easy
16:09
but i myself, have openssh in the chroot
16:10
<dgroos>
thanks for the sample lts.conf -- I've got that most basic--am running firefox and another program as localapp all the time.
16:12
I'll take a look at the pastebininit, thanks. And, unfortunately I've got to let go of this problem right now but good news... It will still be there tomorrow! ;)
16:12
<abeehc>
my xvinfo matches onthe client so that's no issue
16:12
<dgroos>
thanks abeehc and andygraybeal
16:12
<abeehc>
good luck
16:13
