Video cards

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)
01:00.0 VGA compatible controller: nVidia Corporation GT215 [GeForce GT 335M] (rev a2)

$ cat /sys/kernel/debug/vgaswitcheroo/ switch
0: :Pwr:0000:01:00.0
1:+:Pwr:0000:00:02.0

Intel works, after procedures:
# echo ON > /sys/kernel/debug/vgaswitcheroo/switch # enable discrete video card
# echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch # ask if necessary to switch to a discrete graphics

card
# echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

I get a disabled discrete and still working intel card...
$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch
0: :Off:0000:01:00.0
1:+ :Pwr:0000:00:02.0

How can I solve the problem?
nvidia drivers are installed, but if I install nvidia-current, then /sys/kernel/debug/vgaswitcheroo/switch disappears ...
and then if I try to run nvidia-settings, it says to run nvidia-xconfig
if I do nvidia-xconfig, then Xs won't start anymore , they say something like the monitor is not selected ... I
delete xorg.conf and then the x's start, but nvidia-settings does not start ...

what to do? :) laptop www.citilink.ru/catalog/computers_and_notebooks/notebooks/572722/
