After locking my computer, I cannot unlock it. I have had this effect since installing the new system. After locking, the computer does not respond to the mouse or keyboard, it is turned on, but the login screen is not displayed.

The only solution is to turn off the computer and turn it on again.

Ubuntu 20.04 64-bit Wayland Dell latitude 5490

Does anyone know maybe solving this problem?

  • I found this regarding screen lock : https://askubuntu.com/questions/1243491/lock-screen-does-not-work-on-ubuntu-20-04#1243552 See if this is possibly contributing to your issue –  Sep 06 '21 at 23:12

  • I have similar problem, but after update to Ubuntu 21.10. Found this solution https://ubuntuforums.org/showthread.php?t=2456023 – Collector Feb 11 '22 at 08:27
  • I have a similar problem. suspend/unsuspend works, but automatic screen blank makes the computer unrecoverable (doesn't respond to ctrl-alt-del, alt-f1 > alt-f2 etc.). Had it earlier too, I think I've changed some bios power management stuff to make it go away. Recently I've experimented with BIOS some more while installing new RAM, and the issue is back. I imagine my issue must be related to wake up settings or power management settings. – Barnaba May 02 '23 at 12:33
  • I've examined some logs and found out this was my issue: https://gitlab.freedesktop.org/drm/amd/-/issues/1819 - I hope getting a mainline kernel will fix it. Comments suggest it was fixed in kernel 5.17.9 – Barnaba May 03 '23 at 10:33

I have solved problem on 22.04 LTS by switching to the lastest version of proprietary Nvidia driver and X11 windowing system. By the way, it solved another problem - suspend problem. Maybe it will help you.

ubuntu 22.04 can't suspend
