[gentoo-user] libGL issues AIGLX slowness

[Marco Calviani]

Hi all,
 i've managed to install the radeon opensource drivers on my Radeon
9700 laptop (with also direct rendering enabled). However, whenever i
launch a 3D application the following error appears:

libGL warning: 3D driver claims to not support visual 0x4b

In addition to this i've tried to enable AIGLX, it works (that is it
starts), but it is VERY SLOW, and i think this is related to the
preceding error.

NB: i'm not using any overlay, just what is normally available in Portage.

Any ideas or experiences on this?

Thanks in advance,
M

PS: From here https://bugs.freedesktop.org/show_bug.cgi?id=6689
it seems that this error should be purely cosmetic.
Can someone confirm this?

Hi Mike,


I am getting the same error, but with Fluxbox as my default WM I haven't tried
AIGLX.  glxgears seem relatively slow comparatively to the old monolithic
xorg.  I've posted about this error in an earlier message on xorg upgrade.


actually i'm getting better result on glxgears than before. ~5650 FPS
Did you get any reply regard this error?

Regards,
m
