Re: xsrc/42262: Thinkpad T500 Intel GM45 Express X doesn't like i915drm

[Frank Thieme <frank%fthieme.net@localhost>]

I have a Thinkpad SL300 with the same problem (and I guess same graphics
hardware). I just tried the http://netbsd.org/~jmorse/drm4.diff and at
least Xorg starts with DRI enabled and without leaving an unusable display
behind.

But it's not over yet, because every application, that try to use DRI is
getting an Segfault:

$ glxgears
Failed to initialize GEM.  Falling back to classic.
Segmentation fault (core dumped)

Core was generated by `glxgears'.
Program terminated with signal 11, Segmentation fault.
