Works inalaska, after the procedure:
# echo ON > /sys/kernel/debug/vgaswitcheroo/switch # enable discrete graphics card
# echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch # ask for the case to switch to the discrete graphics card
Now click in the "log out", login again, and switch off the integrated graphics:
# echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
Get disabled discrete and still running the 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?
driver NVIDIA are, but if you put nvidia-current, then /sys/kernel/debug/vgaswitcheroo/switch disappears...
and then if you try to run nvidia-settings, it says to run nvidia-xconfig
if you do nvidia-xconfig, the x does not start anymore, saying something like you have not selected the monitor...
remove xorg.conf and then x will start, but nvidia-settings and do not run...
what to do? :) laptop
