Screen stays blank when exiting X (i810)

[Michael Voucko]

Hi,

I'm stuck with running Xorg-6.2.8 on my laptop (Lifebook S-6010).
(I'm pretty new to the whole X thing so please bear with me)

Here is what I did.
- installed Xorg-6.2.8 (on a fresh FreeBSD 5.4 if it matters?)
- ran 'Xorg -configure'
- copied the newly created xorg.conf to /etc/X11
- tested xorg.conf with 'Xorg -config /etc/X11/xorg.conf'

Everything worked fine.
But when I try to use KDE or simply put 'xterm' in my .xinitrc there is no way 
to exit the X server and return to the console - the screen would flicker two 
more time and afterwards stay black and blank. The keyboard does not allow me 
to type to the console - but is still operational as I'm able to switch to 
another virtual console and can blindly enter something like 'reboot' to 
recover from the dead screen.

Observable difference in the logfile is

* last entries in Xorg.0.log when exiting 'Xorg -config /etc/X11/xorg.conf'
(WW) I810(0): Setting the original video mode instead of restoring
         the saved state
(WW) I810(0): Successfully set original devices
(II) I810(0): xf86UnbindGARTMemory: unbind key 5
(II) I810(0): xf86UnbindGARTMemory: unbind key 1
(II) I810(0): xf86UnbindGARTMemory: unbind key 3
(II) I810(0): xf86UnbindGARTMemory: unbind key 4
(II) I810(0): xf86UnbindGARTMemory: unbind key 2

* last entries in Xorg.0.log when exiting KDE or xterm
(WW) I810(0): Setting the original video mode instead of restoring
         the saved state

I tried some of the options available for i810 but either I didn't choose the 
right combination or they dont make any difference for my situation.

I started out with checking the FreeBSD specific mailinglists and archives but 
did not find any explanation or solutions. So I hope that this is the right 
spot to ask this question.

Does anybody know what the problem is or can point me in the right direction?
Is there more information I can provide to track down the problem (xorg.conf is 
attached)?

Thanks
  Michael
