I have tested Intel adapter. And test results shows problem with bright= ness=20 control. Brightness level stop changing after loading kernel. Another p= roblem=20 I found is that laptop just hang during shutdown. I suppose that hang m= ay be=20 related to VT switch, because it still dont realized in case of Intel K= MS=20 driver. USB works fine. For example suspend/resume passed fine when USB flash d= ive=20 inserted. And after resume I can access files on that volume. I found only one problem: If at suspend time I have running VM Windows = XP then=20 resume process will fail.=20 On Wednesday 06 March 2013 21:21:05 =D0=9B=D1=8E=D0=B1=D0=BE=D0=BC=D0=B8= =D1=80 =D0=93=D1=80=D0=B8=D0=B3=D0=BE=D1=80=D0=BE=D0=B2 wrote: > Unfortunately, I knew that NVIDIA works.

However, issuing halt or shutdown -h now, just results in a reboot after key is pressed. Not a problem, I just hold power button at that point. -- Lyubomir Grigorov (bgalakazam)
