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:/
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.
