Kubuntu + switch user = crash
I've search for about 40 minutes and am very busy, so please forgive me if I missed a thread on this topic, but I really need to get back to work.
Using Kubuntu Dapper LTS, 792 MB memory, Pentium 4, ATI video card with latest driver working nicely thank you very much, etc. etc.
My wife tried to switch users on the laptop this morning, and was dumped to at TY screen that looked like what you see when you boot and don't have any Usplash enabled, except it halted part-way through, and stalled there. No KDM login manager, nothing. This necessitated restarting the system, which could have meant my losing 6 hours of work, but like a good computer user I backed everything up.
I tried to replicate the problem, and it happened every time --Kicker >> Switch User >> Lock Current & Start New Session, kaboom.
/var/log/Xorg.0.log shows a whole lot of:
drmOpenByBusid: drmOpenMinor returns -1023
drmOpenDevice: node name is /dev/dri/card223
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: open result is -1, (No such device)
drmOpenDevice: Open failed
xorg.conf file is below.
I'd really like to get this solved; this only happens on our laptop, not on the desktop, and the desktop is busy doing other stuff right now so can't be bothered by us switching users all the time. If anyone has any insight on this, shine a light on me.
