After installing the good-bye-gdm-flick GNOME extension on 18.04.4, I am no longer able to log in. After logging in, only a purple screen is shown (mouse cursor active).
My next course of action would be to uninstall (delete) or disable the extension, but as far as I understand this cannot be done globally, but only in the user's home directory
But the user home directory is encrypted, so if I open a root shell in recovery mode I can't delete the extension.
I managed to mount the decrypted user data to
ecryptfs-recover-private, so my question is this:
If I edit the recovered data in the
/tmp directory, does this have an effect on the encrypted data? i.e. is it possible to delete the extension in this way, or is the recovered data only a copy of the original data?
If so, is it in any way possible to delete/modify files in an encrypted home directory?
Or is there a possibility to somehow disable gnome extensions globally so the faulty code is not executed after login?
The answer of @ashvatthama of logging in via TTY worked!
Minor note for future readers: Don't know if this was only a glitch but I had to change to lightdm before I could open a TTY on the login screen. (I did this via
dpkg-reconfigure lightdm from the root shell in recovery mode).
