Hello - on latest update last week (Thursday - 10th May) all went good with update.
Today, in gnome-login password is accepted, but after short while, then gnome jumps into protected mode and there password is not accepted.
It looks like a worm or a kind of ransomware, but which works not entirely as malware, because hard-disk is encrypted.
a) How can I in protected mode: de-install gnome and gdm - install different window-manager - and then reboot ?!
The idea and hope is, that only gdm or gnome-files are infected
b) ... how can I do this, despite of, that password is not accepted ?!
