Hi there,

just installed ubuntu 12.04 x64 on a ivy-brigde laptop with dedicated ati 7970m.

My problem is, that "vgaswitcheroo" is missing and I am unable to deactivate the discrete GPU.

I mount debugfs on boot.
No propriatery drivers for the ati/intel graphics are installed.

root@lapbecksubuntu:/home/michael# lspci |grep VGA
00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Device 6800
The kernel reports to be compiled with vgaswitcheroo:
root@lapbecksubuntu:/home/michael# grep -i switcheroo /boot/config-3.*
Whats wrong?

Help is very appreciated.
