Debian 11 MATE Desktop - Black screen or almost black screen after login
The laptop screen goes almost completely black after the login to MATE Desktop has completed. Cause: the brightness settings in the power settings can be too low. Solution: Connect external monitor, then edit the brightness settings in System, Settings, Power management. You can also temporarily disable the power daemon in System, Settings, Personal, Startup programs.
