Public bug reported:
Binary package hint: xserver-xorg-video-intel
started out with laptop going into low graphics mode after message "(EE)
intel(0): [drm] failed to remove DRM signal handler" so I subscribed to bug
report 306916 as it seemed to report same error. The suggestion there was to
install intrepid test driver code " 1. Download and test .debs for intrepid,
from:
https://edge.launchpad.net/~intel-gfx-testing/+archive"; which I did. After
that I started experiencing occasional failures in even getting X loaded as
Ubuntu startup would hang with black screen at point where login screen usually
appears - no log file created so it looked like X never loaded. This would
repeat unless I went in "safe mode" once then back to normal. Even when it
loaded Ok I would occasionally get the whole desktop hanging up without
warning.
In that case Xorg.0.log contained lines "[mi] EQ overflowing. The server is
probably stuck in an infinite loop" (see attachment for whole session).
I am using Ubuntu 8.1 Intrepid on a Lenovo 3000 C100 laptop with Intel GMA 900
graphics card, max screen 1024x768. Used to run Redhat fedora without any X
problems or graphics problems.
Am now forcing use of Vesa graphics driver as this seems to give me less
problems although I have had one hang on startup and attach log file for that
session too (or would if I could see how to attach 2 files!).
