Ubuntu: inverted colors after suspend



Question:

Often, after my computer wakes from suspend, the colors shown on the monitor are inverted (or something, it looks rather bizarre). Any idea of the cause? So far, the only fix I have is to restart the computer.

Version: 16.04 LTS

(My monitor is plugged into the) graphics card: Gallium 0.4 on AMD TURKS (DRM 2.43.0, LLVM 3.8.0)


Solution:1

Instead of a reboot try this command:

sudo /etc/init.d/lightdm restart  

If this doesnt work restart the module :

lsmod | grep amd               <- search for the module name   sudo modprobe -r *module-name  <- unload the module  sudo modprobe *module-name     <- load the module  


Solution:2

I keep having the same problem. The temporary solution I have found is to enable guest account. This will allow you to switch account which then fixes the issue.
