I'm mostly using this machine as a web server and with ssh (works fine!) so I rarely see the graphical screen. When I looked however, I saw only the green Mint logo on black background like you see it in the startup phase. White dots are there but not moving.
As far as I remember, the monitor worked fine in Mint 18 - I'm not sure when this started to fall apart, maybe months ago. Maybe I thought I would wait a little until a future update might iron it out. So far, no success with that strategy
Which options do I have to systematically "repair" Cinnamon desktop from commandline?
Thanks -
lsb-release says "Linux Mint 19 Tara", kernel is 4.4.0-109-generic. What else could I bring to the table?
