hello guys. i have this weird problem with ltsp 5. i'm running the version shipped with ubuntu 10.04. the server is amd64 but thin client chroot is i386. everything works fine (thin client boots over NBD without problems) but when i try to log in after hearing the logon sound Xorg seems to crash on thin client and I'm back at ldm prompt.
04:37
what is more when I press ctrl+alt+f1 to go into console my monitor says that this resolution is not supported but *only* if I do that after trying to log in. before logon attempt the text console works fine

what I have observed is when I hit enter after the password prompt in ldm and quickly press ctrl+alt+f1 before GNOME is starting to show up the thin client logs on fine. and then when I switch back to Xorg it crashes and I'm losing VT1 too like I've said
04:40
the thin client is pretty old hardware. it has 800Mhz VIA cpu (i386), 256mb ram and an S3 ProSavage video adapter
04:41
I don't know what configuration details are relevant here so feel free to ask. I will appreciate any help. Thanks in advance.
04:42
and btw. I've checked every possible log and no error message of any kind shows up

masterm: you may want to try this for starters ^^^

Also check the user's ~/.xsession-errors

alkisg: thanks a lot. will give it a try.

15:26
Does this give a hint?
15:27
<Appiah>
O_o
15:27
dont past that much in chan
15:28
you got some vncserver installed there?
15:28
"vino-server"
15:30
<rwmarch>
Yes. Synaptic shows the vino package installed.
15:30
<Appiah>
well what's it doing there trying to launch a vnc session for your ltsp users?!
15:30
pastebin your lts.conf
15:31
<rwmarch>
I dunno. I have not used VNC. I will pastebin lts.conf.
15:39
<johnny>
ah.. it's kde
15:39
try with gnome..
15:39
rwmarch, you're not trying to log into a user that you're also logged into the server are you?
15:40
<rwmarch>
http://pastebin.com/h9tfPszv for the lts.conf.
15:42
KDE? I am using gnome. Ubuntu Lucid 10.4 LTS alternate CD install.
15:42
<johnny>
on.. what's that drkonqi thing..
15:42
seem to be missing some line breaks there..
15:43
also.. try without the X_VIDEORAM
15:43
<alkisg>
That's not all on the same line, is it?
15:44
And SCREEN_07 = LDM should be lowercase, SCREEN_07=ldm
15:44
<rwmarch>
No. Problem user not logged in elsewhere, although it is possible to log in in more than one location for the user that is functioning OK.
15:44
<alkisg>
There's one user that is functioning OK and another that is not?
15:45
<johnny>
no.. it's not a good idea to login as one user multiple location
15:45
for example.. firefox will puke
15:45* alkisg has finally implemented teacher screen broadcasting. Goodbuy iTalc, you won't be missed :)
15:46
<alkisg>
*bye
15:46
<rwmarch>
Line breaks got dropped in the pasting somehow. will try without X_VIDEORAM (which is called for by disklessworkstations.com.
15:49
Correct. One particular user - no problem. userid 1000. The problem users are additional users subsequent to system install. And once in awhile a problem user will successfully complete a login.
15:54
<alkisg>
Try that compiz-disabling line above, it might work for you.
15:58
<rwmarch>
Removed X-VIDEORAM and restarted thin client no fix. The terminal is one of Mr MacQuillam's T1220 units. Will de-activate compiz
16:02
Is there an error in the compiz commandline above? I got "Couldn't find the XML root directory in the address `xml:readwrite' "
16:07
<johnny>
doubtful
16:07
as it's been used by tons of people
16:08

Occasionally a problem user will login successfully. See .xsession-errors for a successful login at: http://pastebin.com/XjpztjUY
16:35
The same user failed moments later: http://pastebin.com/njBZAL7k
16:38
<alkisg>
Did you try that compiz line?
16:39
<rwmarch>
Still working on it. Pasting the above commandline failed.
16:39
<alkisg>
What exactly did you type?
16:39
(paste)?

16:41
<rwmarch>
OK. I misinterpreted the embedded smiley. Got you now.
16:42
Done. Will test.
16:47
Seems to be fixed. Over several attempted sessions for the problem users, all logins succeeded. Thank you very much for helping me.
16:48
<alkisg>
You're welcome. It'd be much faster if not for the smiley :)
16:48
<rwmarch>
Right on.

Now what is compiz. A windowing enhancement? How will life be without it. ;-)
16:50
Why did compiz not effect one user? How to re-instate it in the future?
16:50
<johnny>
that one user had better drivers
16:51
the pc that is
16:51
understated enhancements mostly
16:51
at least by default
16:51
like the menus kinda pop
16:51
and the way they fade into view
16:51
<alkisg>
(or he had selected "none" in the appearance dialog effects tab previously)
16:51
<johnny>
or out of it
16:53
<rwmarch>
Three users on the system - 1000, 1001, and 1002. All set to none in the appearance dialogue. Never a problem for user 1000 to login on the terminal.
16:53johnny has left #ltsp
16:54
<alkisg>
rwmarch: by default, there's no selection in that dialog. That's *different* than selecting none.
16:54
So a new user has compiz enabled by default.
16:55
<rwmarch>
Are you saying that the appearance dialogue has nothing to do with compiz? I do not understand.
16:55
<alkisg>
cat /home/username/.gconf/desktop/gnome/session/required_components/%gconf.xml
16:55
Do that for all 3 users (you'll need a "sudo" in front of it)
16:56
If it says "metacity" in that file, then that user was using metacity instead of compiz, that's why he didn't have a problem.
17:00
<rwmarch>
For the non-problematic user, it says metacity. For the both of the problem users, %gconf.xml does not exist. Could that be?
17:01
<alkisg>
Yes, it's what I'm trying to say
17:02
That user had selected "none" in the effects tab
17:02
The other 2 users had not selected anything.
17:09slidesinger has quit IRC
17:11
<rwmarch>
Even though the problem users showed "none" selected in appearances before I had disabled compiz. . Attempting now to select other than "none" for a problem user fails (presumably because compiz is disabled). Right?

<rwmarch>
Well, thank you very much for giving of your time to me. One more step along the road from OpenSUSE and LTSP-4.2 towards Ubuntu and LTSP-5. Thank you.
17:15
<alkisg>
rwmarch: the command you run made the setting mandatory
17:15
So *now* all the users show "None" in that tab, can that can't be changed
17:15
*Previously* the "None" bullet was *not* selected for those 2 users.
17:16
(i.e. no bullet was selected at all)
17:16
That dialog is a little misleading. No bullet selected means "compiz". If one selects the "None" bullet, it means "metacity".
17:17
But now that you've made that setting mandatory, all users will have the "None" bullet preselected.
17:17
<rwmarch>
Gee. I thought I recalled that I had looked at them earlier, before de-activating compiz, to see if they were the same settings as the non-problem user. I thought that I saw the none bullet filled. Maybe I am wrong.
17:19
Have you seen this compiz issue before? Am I the one and only?
17:19
<alkisg>
Nah, many people have been bitten by it
17:20
(that's why it was the first thing I mentioned to you :))
17:20
Anyway, time to go, goodnight all.
17:21
<rwmarch>
If I re-instate compiz, then I can explicitly set "none" for each and every user?
17:21
If so, how to re-enable compiz.
17:21
<alkisg>
Sure, you just need to delete that setting. Run sudo gconf-editor and then select "show a mandatory window" and delete that setting
17:21
(or directly edit the /etc/gconf.d/mandatory etc file)
17:21

17:21
<rwmarch>
OK, thanks for your time.
