It all started when I installed nvidia's own driver. Uninstalling it and reverting back to nvidia-current didn't solve the problem, so I have been playing with this for a while. Now nvidia-current seems to be functional. It seems glx support is missing, and my intel graphics is not responding. gnome loads only in fallback mode.

Here are some outputs:

glxinfo
name of display: :0.0
Error: couldn't find RGB GLX visual or fbconfig 

glxgears 
Error: couldn't get an RGB, Double-buffered visual

optirun glxgears
works fine

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor      Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff)

how can I fix this? thanks,
