I suffer from the (apparently) widespread problem of Ubuntu 22.04 freezing completely after locking my screen. This is my system:

Thinkpad Laptop E480

  • 64 bit system
  • 8GB RAM
  • Intel i5-8250 CPU @1.60 GHz
  • Intel UHD Graphics 620
  • Ubuntu 22.04.1 LTS
  • Kernel: Linux 5.15.0-58-generic

This happens either if I lock it via Super + L or if the Laptop goes to auto-lock after a certain time. Meanwhile, I have de-activated the auto-lock. Funny enough, this started happening on Ubuntu 20.04, which is why I updated to 22.04, hoping the issue would be gone. Yet, it stayed.

Running echo $XDG_SESSION_TYPE yields x11.

I have checked all related stuff here on Ask Ubuntu and elsewhere on the web, but no solution has helped so far. There is a lot of stuff going on regarding NVIDIA drivers, yet I am running an onboard Intel graphics card.

Things I tried so far that have not helped:

  • Switching between gdm3 and lightdm
  • Switching from Weyland ("Ubuntu") to "Ubuntu on Xorg" (using the settings wheel upon login)
  • Newly installing all drivers (sudo ubuntu-drivers autoinstall)
  • Made my swapfile significantly bigger (from 2GB to 11GB)
  • Not a single keyboard combination worked so far (not Ctrl + Alt + F1 and not Ctrl + Alt + F2)

Any help is duly appreciated, I'm desperate. Next step would be to step away from Ubuntu and try some Ubuntu flavour or abandoning Ubuntu altogether, but that I really would like to avoid. Thanks!

If you need any further info on my system, please let me know.

  • Randomly, the last suggestion of this post regarding pm-utils seems to have had a positive effect. I will keep an eye on the situation and report back. https://askubuntu.com/questions/1407527/super-l-cant-login-22-04wayland/1407530#1407530 – Yannik B Jan 28 '23 at 18:55
  • Locking the screen with Super + L works once I have send the Laptop to suspend once using pm-suspend. Yet, I have to do it again every session. Therfore, I now have a script that runs every time after login and sends the PC to suspend (via pkexec). This is far from perfect, but simply running pm-suspend does not help either, because the screen is not locked when you wake it up. – Yannik B Jan 30 '23 at 18:00
