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.

  • I removed nvidia drivers, and now those issues are gone, but no effects:-( – Prasad RD Apr 29 '12 at 4:34
  • I have the same problem. This may work, but it doesn't "just work." Is there a way to do this automatically after resuming from suspend? Or a way to fix whatever the problem is in the first place? – Josh Mar 14 '13 at 0:30
  • @Josh Wait for a driver patch or use supported hardware. – RobotHumans Mar 14 '13 at 0:38

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)
