Description Michal Hlavinka 2009-04-29 11:21:42 UTC 
Description of problem:
When repeatedly switching from one user to another one, sometimes background is not redrawn completely in screen lock (it should be black with password dialog), but about one third of the screen is filled with grey and white chessboard. But I  don't know if it's nouveau related or KDE4 related. See attached screenshot.

tested on Fedora 11 Snap1 x86_64 Live KDE

How reproducible:
10 %

Steps to Reproduce:
1. start another session and log in
2. switch from first to second and back (no need unlock screensaver)
3. repeat step 2 several times
  
Actual results:
about one third of the screen is filled with grey and white chessboard

Expected results:
black screen with password dialog

Can you test with the "nv" and/or "vesa" drivers and see if the problem is reproducible there?  Also, your Xorg.0.log and the output of the dmesg command after the issue has occurred would be useful.

Thanks!

I've tested it with nv (rpm -e xorg-x11-drv-nouveau and reboot), but wasn't able to reproduce it. Then I've tested it with nouveau in Fedora 11 Prev1 x86_64 Live KDE, but I wasn't able to reproduce it with this newer version.

Ok, thank you.  I'll close this a fixed then!
