I run xfce on my ubuntu server and I just upgraded from 18 to 20.04LTS. Suddenly a power saving or screen saving setting has kicked in that wasn't there before, so it's blanking the screen after 10 mins or so.
I have disabled the screensaver and the lock screen functionality in the Settings dialog. I just tried to fix it by installing xfce4-power-manager and disabling all the power saving features there, but no luck.
Thanks
