Hi!
The bug seems to be back with Intrepid.
Before (in 8.04.1) on my X40 laptop (Intel 855GM) I used i810 driver and it worked ok.
Now, in Intrepid Ibex 8.10 there is no more i810 driver - and so I am stuck with Intel driver.
It already caused me headaches, namely with these random black screen hangs.
However, there is a documented "fix" - it's in the intel manpage, tho not entirely mentioned as a fix to this issue.
What you need to do is:
edit /etc/X11/xorg.conf
and add into the video card section:
Option "ForceEnablePipeA" "true"
then save it, and restart X.
It works over here, as a side (??) effect I get more accurate brightness settings :-)
So try it out and then let the intel devs know about it, just like that manpage says!
Cheers!
