Hi, I don't believe that dimmer control has much affect here. As stated in the OP even xset dpms direct commands fail to sleep or suspend the screen. More than likely this is a bug in the kernel, as the latest nvidia drivers in earlier kernel versions would work successfully.
That said, I'm happy I can finally suspend and resume the machine as a whole without random lockups, so I can live with a fading back light until this is addressed =) -cf On 06/06/2012 05:09 AM, Ashton Fagg wrote: > On 6 June 2012 20:49, mflorea<[email protected]> wrote: >> This issue is more serious than it sounds.
