Description Wei Wang 2006-12-29 18:02:26 UTC 
On intel platform i945g.
For the purpose of testing AIGLX, I utilize LIBGL_ALWAYS_INDIRECT=1 and bring 
up X and glxinfo reports "direct rendering: No". X starts up successfully 
however glean complains out the following errors:

---------------------------------------
basic:  PASS rgba8, db, win+pmap, id 35
X Error of failed request:  GLXBadContext
  Major opcode of failed request:  143 (GLX)
  Minor opcode of failed request:  5 (X_GLXMakeCurrent)
  Serial number of failed request:  35
  Current serial number in output stream:  35
---------------------------------------

Reproduce step:
1. load kernel modules, intel_agp, drm.ko, i915.ko
2. export necessary environment varialbes
3. export LIBGL_ALWAYS_INDIRECT=1
4. bring up X
5. make sure glxinfo reports "direct rendering: No".
6. run glean
7. error happens
(NOTE: step of 3. and 4. can be exchanged, and the behavior is the same).


Misc:
If unset LIBGL_ALWAYS_INDIRECT, glean can run and generate logs and results 
normally.

AFAIK rendering to GLXPixmaps just isn't supported yet.
