Hi all,
I recently switched to a different notebook, with an Intel Core i7 (integrated graphics disabled) and an Nvidia NVS 3100M. The backlight control with Nouveau works perfectly, the buttons to increase/decrease brightness are recognised and even auto-brightness works flawlessly.
However, if my screen locks, it should turn off the screen (including the backlight) in like 5 minutes. What happens, though, is that the screen gets all kinds of stripes (horizontal and vertical) and sometimes even starts flickering. When I move my mouse, everything turns to normal again (apart from some flickering which disappears after some time).
The strange thing is that when I turn off the screen in KDE display settings (to work for example on an external display) the backlight does turn off, however the stripes/flickering continues. It seems to be an error in Nouveau or something, but I haven't found any info on the Internet yet and I don't have any clue how to debug this problem.
Does anyone have an idea where the root of this problem is located and (more important) how to fix it?
Not realy a fix, but I've seen reports in the forums that using the proprietary NVIDIA driver fixes this. You might also have a look at the suse-prime package. There's also Bumblebee, to deal with NVIDIA Optimus configurations. -- Gertjan Lettink, a.k.a.
