[Bug 573101] Re: No video signal after Log out in gnome when multiple users

2010-12-09 Thread MarcelD

*** This bug is a duplicate of bug 546578 ***
https://bugs.launchpad.net/bugs/546578

David,
I have to disagree with re-entangling two bugs, which seem to be copycats (i.e. 
displaying similar behaviour). 

The blackscreen bug #546578 (duplicates #529882, #555298, #555870,
#557779, #570687) appears after a few user switches, which can happen
with only ONE user on the system. For some people the resolution has
been to apply xgamma…  The bug has now been related to a fade-out
problem in the gnome-screensaver.

The blackscreen bug #573101 (duplicates #560911, #561538, #573101,
#574909, #577219, #578979, #585685) appears only with MULTIPLE users on
the system. The blackscreen appears after one user logs out, even from a
failsafe xterm session. So a change to gnome-screenssaver CANNOT be a
workaround for bug #573101 (the failsafe session does not run gnome-
screensaver) and is therefore not a duplicate of bug #54678. This bug is
related to the NVidia driver, which stops the active TTY from displaying
the GDM – LoginWindow session (I have confirmed this with SSH). The
x-update solution by Connie is the definite resolution for this bug.

I would suggest to differentiate between bug #54678 and bug #573101 by
marking them as copycats (not an official launchpad option though, but
references can be placed in the bug descriptions). Please confine
yourself of the difference by reading the bug reports and if so change
the duplicates as suggested above (I will not take the liberty myself at
this point).

Regards, 
 Marcel

It seems patching with xgamma and gnome-screensaver is indeed a
workaround for a problem in the ATI driver. This is what I conclude
after reading more bug reports. I cannot be sure as I do not experience
this bug #546578. I do know from experience that it is not a workaround
for the NVIDIA driver bug #573101, which appears after user logout with
multiple users on the system (as described above).

  I have this bug on both my computer and my laptop.
  This effect me scine Ubuntu Lucid 10.04 alpha to now Beta 2 with all upgrade.
  Steps to reproduce:
  1. Login to user A.
  2. Choose switch user from User A.
  3. Login to user B.
  4. Logout from user B.
  
  After that the screen just go blank. The music from Rhythmbox of user A still 
playing, I can't swith to tty1 (by ctrl + alt + F1), but I can use the Magic 
SysRq key to reboot the system.
  In my laptop it's usally happen, it rarely happen but exist in my computer. I 
think this bug is very critical because I need to use many user for testing 
application and translation of ubuntu.
  There aren't any logs in my computer (except something about Pulse before the 
crash).
  
  And in my laptop has some logs

Hello!

I have installed Ubuntu 10.04 LTS Desktop (lucid) from scratch.
Then I've made 2 users. Then I login as one user and switch to the second
user using gnome menu (not gdm). (New feature in lucid).
When I do Log Out from the second user - video signal disappears and I'm
not able to use neither X nor tty to do something with the system.
I have Nvidia driver (version 173.14.22) turned on. When I turn it off and do
the steps described above - video signal remains, but when I return to the
screen of the first user - the brightness of the screen goes very low. (Fade
bug in Gnome?) And sometimes I even get black screen with lonely mouse. (The
screen is not unfaded).

Maybe there are two different bugs? With nvidia driver (when screen is
reset). And with gnome unfading when unlocking the screen.

Best regards, Vladimir
