[Bug 1965219] Re: gnome lock screen does not permit reentering password

[Stefano Rivera]

Seeing exactly the same symptoms on a machine upgraded to 22.04, with
wayland. Definitely seems suspend-related, but I haven't figured out
what the problem is, yet.

Title:
  gnome lock screen does not permit reentering password

Status in gnome-shell package in Ubuntu:
  Confirmed
Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  Initially, only the mouse works in the gnome lock screen, without any
  way to get a password prompt.  It's likely only happening when
  returning from suspend with lid open.

  It's possible to ssh into the machine or to press Fn+Ctrl+Alt+F?? and
  login without gnome.  After this, Fn+Ctrl+Alt+F1 brings up a purple
  ubuntu login screen, but then after login you simply return to the
  lock screen with no working keyboard.  I never found any method to
  force unlock from ssh or another vt though, so this always still
  required a reboot, or killing all of gnome.

  I've randomly tried some solutions from
  https://askubuntu.com/questions/1242110/after-upgrading-to-
  ubuntu-20-04-lockscreen-not-working  including reinstalling many gnome
  components.  After this, the behavior initially disappeared by
  returning from suspend merely took a long time, like 30 seconds or 1
  minute.  It's possible the delay stems from memory size, but a
  previous identical lenovo x1 had no such problems.

  I've now a worse problem just a few hours later where unsuspend went
  directly to a purple ubuntu login screen, but neither the mouse nor
  keyboard worked.  I've not yet been able to test ssh on this problem.

  It's possibly all connected to recent firmware upgrades, so I'm happy
  to try downgrading the firmware, but I've not found any instructions
  on doing so, or even identifying the firmware upgrade log.
