Description Stanislaw Gruszka 2009-07-15 14:30:02 UTC 
Description of problem:
KDE session is killed and X window system restarts when I switch
to tty and stay there for few minutes. 

Version-Release number of selected component (if applicable):
Fedora 11

How reproducible:
Every time.

Steps to Reproduce:
1. Login to KDE session.
2. Switch to tty (ALT + CTRL + F2)
3. Login to console. 
4. Wait few minutes, X window system should restart 
  
Actual results:
X window system restarts.

Expected results:
X window should perform normally after switch and login to tty

Additional info:
This only happens with KDE and intel driver. I have no such problems
on laptop where I use nvidia graphics. Also problem not happens where
there is only GNOME installed or both GNOME and KDE (gdm is used
on for X window login)

I can reproduce this bug without any custom xorg.conf file.
nomodeset kernel parameter helps.
