I've still not tried other kernels, in part because ubuntu keeps pushing
out new OEM kernels, so I give them all a try, but the same basic
problem persist, either gnome-shell gives only a black screen, or else
the whole system hangs on the purple screen.
I've far more diverse crashes with the latest kernels and the bolt
upgrade:

Title:
gnome lock screen does not permit reentering password
Status in gnome-shell package in Ubuntu:
Incomplete
Status in systemd package in Ubuntu:
Incomplete
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.
