Bug Description
So, I have this problem on lenovo ideapad y460, with hybrid graphics (AMD 5650 and intel) on ubuntu 12.10 with preinstalled open-source video drivers.
To reproduce bug on my system:
1) switch off discrette videocard using vgaswitcheroo:
kirill@lenovo:~$ sudo -s
[sudo] password for kirill:
root@lenovo:~# echo OFF > /sys/kernel/
root@lenovo:~# cat /sys/kernel/
0:DIS: :Off:0000:01:00.0
1:IGD:+
2:DIS-Audio:
root@lenovo:~#
2) switch to any TTY using ctrl+alt+F1..F6
3) switch back to X-server using ctrl+alt+F7
After that I see the scree in state I leave it, but in frost state (for example, I can open gif animation, switch to TTY and back, and after I have static image on screen). Also I can't use keyboard and mouse.
If I try to go to the TTY and back with discrette videocard switched on, it works fine.
I have that bug on 12.10 and 13.04. But 10.10, 11.04, 11.10 and 12.04 work great.
