Changing screensaver causes gnome to reboot/jump to login

English Applications

OpenSuSE 11.0

I noticed that my server if left long enough would end up at the login screen.

After some tracking down I found it was the screensaver being on random so I figured that I just had a screensaver that was causing problems. I tabbed down through the screensavers and any that caused gnome to crash and end up at the login screen I removed from …/screensavers.

However, I then went through the list again and it crashed on screensavers that it was fine on previously. Also, I noticed that it remembered the screensaver that was set when it crashed upon reopening the screeensaver screen and didn’t crash.

The conclusion is that it is not specific screensavers causing a problem but the changing through screensavers multiple times that is causing the crashing and sure enough if I don’t use the Random setting, things work fine on any screensaver.

Can anyone enlighten me as to why this would be happening and more importantly, how to fix it?

I do not have desktop effects on but I am using NVIDIA drivers driving an 8600 GTS video card.

Below is my xorg file which perhaps has something to do with it.

Any help appreciated.
Reggie.

Personally I just disable screensavers, more trouble than they are worth. May be not what you wanted, but the best I can offer is - Try ONE screensaver or Blank Screen. Otherwise disable.

Installed SuSE 11.2 three days ago and have the same problem as Reggie. Changed from GDM to KDM trying to fix it. No dice. Configuring screensaver causes system crash. Does restart. When it was installed in GDM, the monitor was turned off after the time for screensaver was reached (20 min). I would like to cycle through some images as part of work, not only for pleasure. (Does that change this?) So, it would be good to know if anyone could suggest a fix or a place to get some info re this.

In fact, the display properties all act rather peculiarly though randomly.
