[Mesa-users] Fwd: OpenGL Version in Mesa 9.1 at 2.1

Mon Nov 19 15:43:22 PST 2012

Slavko,

 I'm running a sandy bridge but it does appear to be driven by the i915:

00:02.0 VGA compatible controller: Intel Corporation Sandy Bridge
Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
    Subsystem: Dell Device 04da
. . .
    Kernel driver in use: i915

My kernel is, specifically, 3.2.0-0.bpo.3-amd64 which is a backported
Debian kernel. Sounds like I would need to update.

I too am running xf86-video-intel-2.20.13. At least that's what the git log
says.

Also note, I've installed all of this to my home directory and run ldconfig
to use those libraries. Question, how did you determine your xf86-video
version?

Thanks for the input!
