Package: libgl1-mesa-glx
Version: 7.0.3-1
Severity: important

Since my last update I noticed a immense slowdown in the graphics 
performance. Even switching desktops needs up to several seconds. 
Looking into Xorg.0.log I found:

(EE) AIGLX error: drmMap of framebuffer failed (Invalid argument)(EE) 
AIGLX: reverting to software rendering

Same result when starting glxgears:

libGL error: drmMap of framebuffer failed (Invalid argument)
libGL error: reverting to (slow) indirect rendering

Trying to find more information I looked into BTS, but solutions from 
bug-reports describing a similar slowdown (e.g. #480689) do not work. It 
is slow whatever I use, EXA, XAA, or other options.

This is using a Thinkpad X40 with Intel 855GM graphics card:

00:02.0 VGA compatible controller: Intel Corporation 82852/855GM 
Integrated Graphics Device (rev 02)

I am not sure if this is correct package, so reassign to the appropriate 
one, please. Also I set the severity to important, but a higher is 
probably more suitable since it makes other packages almost unusable.

If you have further questions, please send me an email.

Regards,
Sten
