When ubuntu resumes from suspend the screen messed up!, I have installed correct drivers for the graphics card (nVidia geforce 6200 128mb agp) and updated to the latest. This also happens when switching user accounts without login off, I use Ubuntu 12.04 32 bit and my pc is intel p4 3.06Ghz HT 1mb cache LGA,1GB ddr1 400mhz, asus p5pe-vm MB, here are some screenshots. Please help
Suggested steps to get back to a working desktop when you have graphics issues regardless of driver.
The steps I usually try are first CtlAltF1 followed by CtlAltF7. In some cases this will get it working.
After that, if you're using unity-3d(the default) try
unity --replace &
in a terminal. Basically that means launch a new unity to replace the old one.Same problem with Ubuntu 16.10, GTX 750 Ti and 4K monitor.
killall compiz
and waiting for it to respawn fixes it.I have the same issue. If I go into Settings > Displays and click the Apply button, it resets the video and everything is fine again. There should be a better fix that this though.
I am running Ubuntu 16.04. No 3rd party drivers installed. System > Details says my graphics is: AMD TURKS (DRM 2.50.0 / 4.13.0-39-generic, LLVM 5.0.0)
