screen flickering using nvidia drivers

Postby canicola » 2017-06-08 07:06

Hi

I have some issues with one of my screens. I think it is a graphic card related problem. I'm running debian 3.16.34-2 (jessie). I have four screens (Samsung S24E650) for which I bought a new graphic card (GeForce GTX 1050). One display is using the DisplayPort the other three are using HDMI. One of the HDMI display shows some red flickering (horizontal lines). It happens not always and depends what kind of window is active on this screen. I see the flickering when I'm looking at the desktop (standard debian wallpaper) without any other windows. Browsing the web is another case when I see the flickering. I don't see it if I have a terminal (full screen mode) on that screen. The nvidia drivers I'm using are

Code: Select all
las@thinkstation:~$ nvidia-smi
