Bug Description
Binary package hint: xorg
When I updated the system from 9.2 to 10.04 the colours of the X11 Display were very strange - very yellow. I suspected the error in the file xorg.conf and changed the default from 32 bits to 24 bits. After that the display looked correct. When I switch a user from a running session (gnome) to another user, gdm showed me a tiled window with four quarters and only the upper left was correct. Then I experimented with options for the display sections in the file xorg.conf and now the first switch of a user somehow works. But if I switch back to the first user the screen is "nearly" black. I clearly can see the mouse pointer and suspect that everything else, except the display works.
Finally I decided to install a new Ubuntu system (no update) on the same computer but here the first user switch does not work.
The lower part shows "Ubuntu" and there is no gdm window to log in.

Hello,
I don't have exactly same problem, but I found some problems with xorg when I switch user between openned sessions:
PROBLEM: I have session with 1600x1050 and switch to another user's session that was previously set with same 1600x1050 resolution. But when I switch to this session, the screen gets 1280x1024 and for some reason the size of the session is very very wrong (it is bigger than the screen resolution and I can't move or click most of the things so I have to restart all Xorg).
WORKAROUND: Fortunately I have found some way to resolv it in a tricky way:
Change resolution file name with your resolution file.
1-Install get-edid command: sudo apt-get install read-edid LINUX_DEFAULT= "drm_kms_ helper. edid_firmware= edid/1600x1050. bin quiet"
Change your name.bin file.
2-Create a bin file with edid information: sudo get-edid > 1600x1050.bin
3-Create a folder to store this file: sudo mkdir /lib/firmware/edid
4-Copy the file: sudo cp 1600x1050.bin
4-Edit grub to edit linux command to load this file in kms:
-sudo editor /etc/default/grub
-Edit line: RUB_CMDLINE_
-sudo update-grub
5-Reboot and test.
For some reason it worked for me very well.
I have this card and driver:

I was looking for other bug report similar in launchpad, but still looking for the correct one. I would like find a user with same problem I had, because I think this problems affects many things in KMS (Kernel mode switch), not just switching between user session, also games in full screen with different resolution an...
