glxinfo displays visuals correctly for mesa 9.2.5 (SW rendering works ok -
checked with glxgears) but when mesa updated to 10.1.2 I'm getting error:
libGL error: failed to load driver: radeonsi
libGL error: failed to load driver: swrast
Error: couldn't find RGB GLX visual or fbconfig
Error: couldn't find RGB GLX visual or fbconfig

xdpyinfo returns only 3 X visuals (for mesa 9.2.5 it was about 100)
glxinfo return 0 GLX visuals and all GLXFBConfigs have VisDepth = 0

Traced in libGL.so (glxect.c):
GetVisualConfigs returns 0 visuals.

Answering this question would help:
Where in mesa creating/getting information about visuals is done?

XOrg.O.log shows no error.


I suspect the problem is in radeonsi_drv.so, but for sure it's in Mesa.
