Garbled screen on wake

Dual boot laptop seems to awake fine with Windows 10 but not Ubuntu. When booted into Ubuntu and put it to sleep, if left a few hours then woken again, it will show the screen below. This itself goes to black after 10 seconds, presumably due to power saving. I can also still see and move the cursor, but keyboard/mouse clicks do nothing. I end up having to restart the entire laptop to get things going again.

  • Your question is well detailed with specs. However it's missing which nVidia driver is being used: proprietary or the open-source Nouveau. Also if nVidia driver you can try a different version number. Also you can try deactivating nVidia driver and using Intel GPU instead for testing suspending / resuming. Finally you can try using Unity desktop instead of Gnome desktop which also could be the source of the problem. – WinEunuuchs2Unix Mar 3 '19 at 14:21
  • @WinEunuuchs2Unix re:"Finally you can try using Unity desktop instead of Gnome desktop which also could be the source of the problem.". You don't really mean that, do you? Maybe a faulty GNOME extension... or an incorrect Nvidia driver... the correct version is 418.43... released Feb 22, 2019. – heynnema Mar 3 '19 at 14:41
  • @heynnema Well I did say "Finally" and not "Firstly" :) It's mostly a shot in the dark after all other likely problems have been exhausted. – WinEunuuchs2Unix Mar 3 '19 at 16:19
  • @WinEunuuchs2Unix I usually wouldn't consider making such a major change to "fix" a problem. As I say in my comment... lets troubleshoot extensions and video drivers first :-) – heynnema Mar 3 '19 at 16:23
  • @heynnema Duly noted. I've tried Gnome DE a few times and always ended up throwing it out in favor of Unity DE. So I'm biased :p – WinEunuuchs2Unix Mar 3 '19 at 17:05
