I'm on a laptop with Intel integrated graphics and an Nvidia 1060, Ubuntu 19.10, gnome desktop.
The screen lock functionality is completely lost; When I press the lock button from shell or super + L
the screen just goes blank for a second, killing all my open apps and then reopening my desktop as if it is logging out and back in. I suspect this because I have an extension which greets me when I log in and I've also added a vpn to start-up which gets re-enabled when I try to lock.
However, the lock screen (the screen where it asks for password) itself exists and works fine when I log out or reboot.
These are what I've done so far:
- The problem is not existent in a new user account.
- I have tried setting
gsettings set org.gnome.desktop.lockdown disable-lock-screen
to'false'
but it affects nothing. - I have tried
sudo dpkg-reconfigure gdm3
andsudo dpkg --configure -a
to no avail. - I've used
dconf-editor
to look into the settings for abnormalities, found none.
