[Bug 315542] [NEW] X hangs on ubuntu 8.1 intrepid laptop

[erica hollis]

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!).
