Good morning.

I have an Intel sandy bridge with an Nvidia (optimus) GT 525 M (Dell XPS 15 L502x running Debian Wheezy, kernel 3.0). Since I managed to install and run optimus, and I have in my Nvidia graphics acceleration.

However, I want to know if is possible to have acceleration in intel while not in use Nvidia.

~$ 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 Device 0df5 (rev a1)

~$ optirun glxgears -info
GL_RENDERER = GeForce GT 525M/PCI/SSE2
GL_VERSION = 4.1.0 NVIDIA 275.28
GL_VENDOR = NVIDIA Corporation

But without optirun, glxgears sends the following message:

~$ glxgears -info
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual

Thanks in advance for the help.
