I normally use a 19" monitor, but today decided to try a 21" just for fun...turned out to be no fun at all. Everything was working great, beautiful picture, nice color, etc. I decided to change the resolution, just to compare; Bad decision.
In the "old" days, if I wanted to change desktop background, I right click anywhere on the screen and the window opens where I go to backgrounds. I do (did) this often.
The way to get there now is >menu>appearance>background It's not so terrible but I liked the old(easy) way much better.
Now, when I right click in Mate, nothing happens. Mouse works fine in Win10, Plain Ubuntu and Mint Mate. Ubuntu Mate, which I use most of the time, is the only one that went bad.
Tried: the old monitor, 3 different mouse, timeshift, and rebooted a few times. I can’t imagine how I could have done this by changing screen resolution ONLY in Ubuntu Mate?
Does not apply or work for me ( mine worked with "show icons" off)
Possibly restore partition from Clonezilla, but rather not go through that if I don't have to. Thanks in advance for any response.
