A monitor which becomes automatically duplicate even that it is turned off/on

Post by arataj » Mon Jul 09, 2018 1:15 am

If there are two independent screens with independent contents, maximise and full screen should work independently for each.

#### Actual behaviour
After sleep and wake up, the 1st desktop stretches over the size of both screens.

#### Steps to reproduce the behaviour
Configure two independent screens :0 and :1, sleep, wake up. Maximised windows go way past the right margin of the 0th screen. Their are invisible on the 1st screen.

This might be an issue outside MATE, but in any case mate-panel has the correct size, and MATE works correctly with the setup until the first sleep and wake-up.

Re: Desktop size covers to independent screens

It would probably be helpful if you would open a terminal, maximize it to avoid cut off lines, enter inxi -Fxz, then copy/paste the output of that command into your next post here.

Thanks jimallym for your post. I guess you wanted to know the size of the window, but the reason for the behaviour turned out to be different. It is still a problem, however.

I have a main monitor DFP-0 1920x1200 and a small CRT-0 450x310, these are two separate screens 0 and 1. I have also a rarely used projector DFP-1 800x600 and once tried to make it work so that the projector, when turned out, just duplicates the main screen DFP-0. If I am not wrong, it worked fine.

No more. Now the projector either has a bad aspect ratio, attaches itself to the left of DFP-0 at the same screen 0, thus the mentioned maximise problems, or is just invisible. It all depends on whether it was turned off/on during x server startup/wake up, different combinations end in different screen configurations.

I wonder, can the projector be just fixed as a duplicate of DFP-0 as before, and that it works like that always, I just turn the projector on and it becomes a duplicate, with a correct aspect ratio. The projector, despite its low resolution, handles 1920x1200 fine.

I attach my current xorg.conf, thanks.

He didn't ask for your xorg.conf, he asked for the text output of inxi -Fxz. Hint: in Linux you have to really read the directions, not sort of.

He didn't asked for your...'opinion', he asked for technical advice (after proving a very specific description of his setup as well).
Hint 1: In 'Linux' (and life in general...), if you don't really have something specific to say, then better don't.
Hint 2: He appears to know more than you about...'Linux'.
