Hi, I need help please. I would like to know how to restore my desktop. I wanted to try unity desktop, so I did
`apt install ubuntu-unity-desktop`
Now every time I reboot and reach the login, I have a black screen. I have to do
systemctl restart lightdm
I see the login screen has been replaced by unity configuration.
Also when I finally reach the mate desktop, the window decoration and cursor config are messed up.
