Debian 9 desktop distorts upon waking from suspend

Postby HangryDave » 2017-08-09 18:31

Hey,

Whenever I wake Debian 9 from sleep, the screen distorts, sometimes on the login screen, sometimes on the desktop background.

I would include technical info, but I don't know what is needed to diagnose the problem. The one thing I know might help is the fact that I am using an Nvidia GTX 750ti.

Worth making a quick check of graphics software using inxi package.

After installing inxi do :

Code: Select all
inxi -G


Here is a result from my system for comparison :

Graphics: Card: NVIDIA GM107 [GeForce GTX 750 Ti]
Display Server: X.Org 1.19.2 driver: N/A Resolution: 1680x1050@59.97hz
GLX Renderer: Gallium 0.4 on NV117 GLX Version: 3.0 Mesa 13.0.6

Sometimes see a carpet of crud like that after a fresh install, but never persists on my 750 Ti

I completely forgot about this, as I haven't used Debian on my main machine for a while. My output of inxi -G is:
Code: Select all
Graphics:  Card: NVIDIA GM107 [GeForce GTX 750 Ti]
           Display Server: X.Org 1.19.2 drivers: nvidia (unloaded: modesetting,fbdev,vesa,nouveau)
           Resolution: 1920x1080@59.93hz
           GLX Renderer: GeForce GTX 750 Ti/PCIe/SSE2
           GLX Version: 4.5.0 NVIDIA 375.66

Best if i let someone else help further with that 375.66 nvidia driver.
Never used it on Debian and had my fingers burnt trying the likes on other distros when updates come along.
