When I awake Ubuntu 19.04 from sleep, the wallpaper looks very weird. As if it was corrupted or something like that. I can change wallpapers normally on settings, and it will be back to normal. But as soon as come back from suspended mode, it becomes weird again.

Wallpaper after returning from sleep

    Probably a video driver problem. Open Software & Updates app, Additional Drivers tab, and tell me what you see. What video card make/model do you have installed? What video driver version? – heynnema May 13 '19 at 22:57
  • I'm using Nvidia driver metapackage from nvidia-driver-418 (open source) and I have a gtx 760 installed. When I upgraded to 19.04 from 18.10, I didn't reinstall drivers or did anything like that. – Jose Guilherme May 13 '19 at 23:34

    I'd reinstall Nvidia 418, or go to their web site and grab the 430 beta. Report back. – heynnema May 13 '19 at 23:51
  • So many problems I've read last few weeks on 418. I'm using 384 with my GTX 970M (newer than yours) with no problem. You should try version 384 too. At the very least people with problems on 418 reported success with 396 and 390 so you could try them. Remember bigger more bloated drivers to support newer cards than yours and mine doesn't always mean better and faster for us... – WinEunuuchs2Unix May 14 '19 at 00:23
  • @heynnema Guess you'd want to read this too ^^^ – WinEunuuchs2Unix May 14 '19 at 00:27
  • @heynnema, I installed the 430 beta, but the same thing happens with the screen. – Jose Guilherme May 14 '19 at 22:00
  • As @WinEunuuchs2Unix suggests, maybe the older 390 drivers would work better. You could uninstall the 430 drivers, then go to Software & Updates, Additional Drivers tab, and I think you'll find 390 there. – heynnema May 14 '19 at 22:05
  • I tried this other versions... doesn't seem to be working. :( – Jose Guilherme May 15 '19 at 00:40
  • Lets do 2 things. Check your BIOS version sudo dmidecode -s bios-version and then go to the manufacturor's web site to check for a newer version. Check your memory, go to https://memtest86.com and download the free memtest. Run memtest for 4/4 passes. Report back. – heynnema May 15 '19 at 15:07
  • I've made an workaround that reloads Gnome on wakeup: https://askubuntu.com/a/1454105/28997 – Narcélio Filho Feb 08 '23 at 18:28
