Ubuntu 22.04 freezes completely after locking screen (Intel graphics)

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

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
