Ubuntu: inverted colors after suspend


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)


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  


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.

Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
