After updating my Ubuntu install to 21.10, my HP laptop freezes after system sleeps, automatically or not. The screen glitches, and I can't input anything with keyboard. I had to hard reset my laptop so I can access again my Ubuntu installation. I never tamper with my system configuration and only use it as end-user, other than modifying keyboard input.

  • I was seeing the same on a Dell latitude 7280. Turning off the sleep after 20 mins feature helped to prevent this but I'm still wondering what causes this.
