Urm. Googling for "ldm" and clicking on "images" shows some non-LTSP-related images... :D
01:46
<muppis>
Funny. :D
01:47
<alkisg>
Maybe we should use one of those and the default ldm background image :P

I'll try booting the way it is now

08:17
<alkisg>
Seta00: I'm not sure I understand your problem. Didn't you get it to boot yesterday?
08:18
And now it won't boot again?
08:18
<Seta00>
yeah :(
08:18
I'm fixing it
08:18
and it was the day before yesterday
08:19
<alkisg>
OK, check if your IP matches the range in /etc/ltsp/dhcpd.conf
08:19
If you have any specific questions, shoot

Got it. Put IP instead of mac to lts.conf
08:36Seta00 has joined #ltsp
08:36
<Seta00>
the client won't login
08:36
nbd_server says disconnect request received
08:37
I'm updating the image file
08:37
@ alkisg
08:37
do you know of any misconfiguration that can cause that?
08:38
what's the TCP port nbd_server uses??
08:42
<mgariepy>
Seta00, 2000
08:42
<Seta00>
thanks
08:42
mgariepy: I'm running dpkg-reconfigure on it, can I use any export file?
08:43
it keeps saying address already in use
08:44
<mgariepy>
usualy nbd server is started by inetd
08:44

I'm trying ltsp-update-sshkeys now
08:46

anyone tell me if LTSP does dual monitors?
10:06
<gnunux>
i've dual monitors
10:08
<sol326>
anything special to make it happen?
10:11
<gnunux>
no, xrandr work fine
10:13
<sol326>
how does ltsp compare with the 2x thinapp product?? any experience with that?

<m4xx_>
how can i configure my ltsp client to use dual monitors each with a different resolution?
11:26komunista has joined #ltsp
11:26
<Appiah>
if you want to configure a specific client you can do so under lts.conf
11:27
add the mac [] and specifiy the xconfiguration needed for dualhead
11:34
<m4xx_>
i'de like each client to be configureable
11:34
or is this not possible?
11:35
the problem is each client is different atm
11:35
<Appiah>
you can specify each client by it's mac
11:35
in lts.conf
11:35
mac address*

http://manpages.ubuntu.com/manpages/lucid/man5/lts.conf.5.html
11:40indradg_ has joined #ltsp
11:42
<Gadi>
m4xx_: you usually need only adjust X_VIRTUAL and XRANDR_OUTPUT_X and XRANDR_MODE_X options, provided the driver can do dualhead with xrandr - not all can
11:42
<indradg_>
hi... i'm using Ubuntu 10.04 LTS and having problem with the thin-clients displaying a wrong time on the login in screen... i've followed the instructions from the Ubuntu wiki (which says its for 8.04) without any avail... any clues?
11:44
<Gadi>
indradg_: TIMESERVER and TIMEZONE
11:44
should be the params you need
11:45
<Appiah>
lts.conf ?
11:45
http://manpages.ubuntu.com/manpages/lucid/man5/lts.conf.5.html again!
11:45
!lts.conf
11:45
<ltspbot>
Appiah: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
11:45
<indradg_>
Gadi, ok... if you could direct me to where exactly to plug them ?
11:46
<Gadi>
indradg_: sure - first off, what timezone are you in?
11:46
<indradg_>
Gadi, Asia/Calcutta
11:47
of +0530 GMT
11:47
<Gadi>
indradg_: ok, have you created an lts.conf file?
11:47
<indradg_>
or*
11:47gorkhaan has joined #ltsp
11:47
<indradg_>
yes... only iTalc entry and a couple more entries in there atm
11:47
<Gadi>
(in /var/lib/tftpboot/ltsp/i386/lts.conf)
11:48
<indradg_>
Gadi, ok... i'm with you so far
11:48
<Gadi>
ok
11:48Da-Geek has quit IRC
11:48* indradg_ is not in front of the system... so it will be more in theory rather than be able to try out
11:49
<Gadi>
you should have:
11:49
<m4xx_>
i dont see XRANDR_OUTPUT_X or XRANDR_MODE_X in the docs
11:49
<Gadi>
ah
11:49
indradg_: so, here's the theory: The thin client is diskless, so the only time it knows about is hardware (BIOS) time
11:49
<Appiah>
m4xx_: For drivers that support XRANDR, the XRANDR_MODE_* variabled are
11:49
preferred. See the XRANDR section
11:50
<Gadi>
indradg_: so, TIMESERVER and TIMEZONE allow you to have the thin client run ntpdate on boot
11:50
<Appiah>
says MODE_00-09 but not MODE_X hmm
11:50
<Gadi>
indradg_: of course, for it to work, the thin client must be able to access the ntp time server from the client
11:50
<indradg_>
Gadi, right!
11:51
<m4xx_>
ah, i'm sorry
11:51
<indradg_>
I do have a local ntp server running on the server
11:51
<Gadi>
indradg_: this means, either installing ntpd on the server OR using a public ntp server and setting up NAT on the server (assuming a 2-nic server setup)
11:51
<indradg_>
Gadi, I've a dual nic setup
11:52
<Gadi>
indradg_: for troubleshooting, do the following:
11:52
indradg_: log into ldm at the terminal
11:52* indradg_ listening
11:52
<Gadi>
indradg_: on the server, run: ltsp-localapps xterm
11:52
indradg_: this will pop open a local xterm running on the client
11:52
<indradg_>
yep
11:53
<Gadi>
indradg_: inside this xterm, you can do things like ping the ntp server
11:53
indradg_: you may not be able to run ntpdate as a user
11:53
<indradg_>
Gadi, yes... need to be root for that
11:53
or a sudoer user
11:54
<Gadi>
indradg_: in which case, you can always create a root password in the chroot, and switch to a local console login
11:54
1 sec - ph call
11:54
<indradg_>
Gadi, sure
11:55leio_ has joined #ltsp
11:56
<vagrantc>
or even still use ltsp-localapps xterm and su
11:56
<indradg_>
vagrantc, cool!
11:58leio has quit IRC
12:00
<m4xx_>
setting the X_VIRTUAL worked to enable the dualhead but when i try to change the resolution on the second monitor the monitor prefferences window freezes
12:01
<Gadi>
indradg_: sorry - anyhow, from the local xterm you can check ntpdate. You can also run: getltscfg -a
12:02
indradg_: that will report to you the lts.conf vars that it sees from your lts.conf
12:02
<indradg_>
Gadi, and check if TIMEZONE & TIMESERVER are assigned the right values
12:02
right
12:02
<Gadi>
indradg_: make sure TIMESERVER and TIMEZONE are in there
12:02
<indradg_>
got it
12:03
<Gadi>
indradg_: aside from that, if it is not working it might be a bug - we set time in the background on boot, and sometimes really fast thin clients may get to ldm before the time is set
12:03
<indradg_>
Gadi, possible... i was using an Atom 450 with 1GB ram
12:04
Gadi, thanks a bunch.. i'll go back tomorrow and have a go at it
12:05
<Gadi>
indradg_: np
12:06
m4xx_: are all of the clients using the same video driver?
12:06
<m4xx_>
not yet
12:06
<Gadi>
m4xx_: because different drivers have different names for outputs
12:06
and so if you need to set different resolutions for each in lts.conf, you are in for a bit of work
12:07
we tried to do automagic stuff, which is why just specifying X_VIRTUAL gets you much of the way

12:20dr_data has joined #ltsp

<Gadi>
m4xx_: btw, that online lts.conf manpage has an error with the XRANDR_ options
12:29
they should all have one digit - not two
12:29
XRANDR_MODE_0
12:29
not XRAMDR_MODE_01
12:31
<vagrantc>
i should get that fixed before squeeze releases...
12:32
<Gadi>
seems to be fixed in 10.10 on ubuntu
12:32leio_ is now known as leio
12:32
<vagrantc>
oh, it is
12:32
there are a couple other minor updates i'd like to include
12:38Lns has joined #ltsp

12:38
<m4xx_>
i'm sorry, i was able to figure out the MODE_X and the X_VIRTUAL, but am unsure of what to enter for XRANDR_OUTPUT_X
12:38
would that be like "SCREEN 1"
12:39komunista has quit IRC
12:59gorkhaan has quit IRC
13:08
<Gadi>
m4xx_: what do you get when you type "xrandr" at that terminal?
13:09mistik1 has joined #ltsp
13:10
<m4xx_>
or perhaps VGA-0 AND DVI-0
13:13dr_data has quit IRC
13:14
<m4xx_>
http://pastebin.ca/2015769
13:16
<Gadi>
so:
13:16
XRANDR_OUTPUT_0 = "VGA-0"
13:16
XRANDR_OUTPUT_1 = "DVI-0"
13:17
XRANDR_MODE_0 = 1024x768
13:17
(would set VGA to that res)
13:17
XRANDR_MODE_1 = 1680x1050
13:17
(would set DVI to that res)
13:17
<m4xx_>
ah,
13:18
no quotes for the mode ?
13:18
<Gadi>
if you want to play with relative positions, you can do something like:
13:18
you can use quotes
13:18
quotes should really only be needed when the value contains a space
13:18mgariepy has quit IRC
13:18
<Gadi>
anyhow, you can also do:
13:18mgariepy has joined #ltsp
13:19
<Gadi>
XRANDR_MODE_1 = "DVI-0 --left-of VGA-0"
13:19
oops
13:19
I meant
13:19
XRANDR_OUTPUT_1 = "DVI-0 --left-of VGA-0"
13:20
to tell it that the DVI output should be to the left of the VGA
13:21
the annoying thing is that output names are not standard, so what may be called "DVI-0" for one driver, may be called "TDMS-1" for another
13:21
:P
13:25
<m4xx_>
could you not use numbered indexes
13:25
instead of the actual name?
13:25mgariepy has quit IRC
13:26
<Gadi>
either the name of the
13:26
output or the XID.

evening all
20:28
I replaced the client-side nic on my ubuntu 10.4 lsp server; had to change the udev rule so new nic is eth1 instead of eth2. How do I restart networking?
20:28
Looks like none of the /etc/init.d/net* scripts are configured to run in the default runlevel (2).
