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.
Hi,
As I said, it isn't an Nvidia Optimus configuration (the Intel graphics are disabled, by hardware). I'm a bit afraid of installing the proprietary drivers, as Tumbleweed often provides kernels which are newer than those supported by the drivers.
You could lock the kernel to a version that the NVIDIA driver does work on. AFAIK there currently are no issues with the 4.x kernels. Driver is reported to work properly on Leap, which has 4.1, not much older than TW.
Because of the single graphics configuration, I don't think opensuse-prime will help much. No, it won't.
