Description Michael Monreal 2009-11-01 15:04:29 UTC 
From a running GNOME session, select "Switch user". In GDM, try to go back to your old session by selecting the user (which is marked with a green check icon). GDM will restart and the old GNOME session is gone :(

My GDM is updated all the way to gdm-2.28.1-20.fc12.i686

Ben says this is not a 530169 dupe. He is working on a fix right now.

Could you please update to the following packages, this issue is hopefully resolved now:

http://koji.fedoraproject.org/koji/buildinfo?buildID=139807 (libdrm-2.4.15-4.fc12)
http://koji.fedoraproject.org/koji/buildinfo?buildID=139811 (xorg-x11-drv-nouveau-0.0.15-17)

Thanks!

> Could you please update to the following packages

Yes, the crash is gone now. I have however noticed that GDM gets "stuck" sometimes (after a few tests it seems to work:fail about 2:1):

- log into gnome
- switch user
- GDM comes up just fine, click user, pass, login
- switch user again
- either it works as above, or:
- GDM fails to load completely. Wallpaper is displayed correctly, the login "window" and "panel" show, but are only gray areas with no widgets or text visible. Also, the busy cursor is spinning, forever. I can ctrl-alt-f2, login there and init 3, init 5 to make things work again

The problem only seems to show if changing users more than once. I have tested this on my other F12 system (which uses nvidia binary driver) and I don't see the problem there.
Comment 7 Ben Skeggs 2009-11-05 09:58:07 UTC 
Same versions of GDM etc on both machines?
Comment 8 Michael Monreal 2009-11-05 10:38:19 UTC 
Desktop (working): gdm-2.28.1-22.fc12.i686
"other machine" => booted from USB live image: gdm-2.28.1-12.fc12.i686 (latest in f12 updates)

Booting my laptop (intel graphics) from the same USB stick brings working user switching (just tested about 20 times in a row and no problem)

But the GDM changelog on koji shows a promising patch, so I will update GDM now and test again on the other box
Comment 9 Michael Monreal 2009-11-05 11:49:57 UTC 
Tested with the newest GDM from koji and it works fine! So we can close this, but I hope a newer GDM build will make it into F12 final.
Comment 10 Ray Strode [halfline] 2009-11-05 14:46:10 UTC 
yea, don't worry, a GDM with that fix got tagged for final a while ago.
