Well, I made the mistake of tinkering with the Monitor & Display settings in the Control Center on my other machine, expecting that the 'Test Settings' button would work like the 'Test' button in the Configure Desktop => Screen Saver does, but no; 'Test Settings' seems to have stored its settings somewhere, there is no evident way to revert the display, and further tinkering has now the monitor is totally unreadable. (I'd provide a screenshot, but as usual, my old Samsung Galaxy 6 phone can't be read by Trinity.)
Fortunately, I can ssh into the broken machine from this one, but I have no idea where Monitor & Display stores its misconfiguration files.
Does someone know where they would be?
Do you have anything in the directory ~/.trinity/share/config/displayconfig/ ?
No. | @15:44:04 leslie@pinto | wd=/home/leslie | $ ls -l ~/.trinity/share/config/displayconfig/ | /bin/ls: cannot access '/home/leslie/.trinity/share/config/displayconfig/': No such file or directory | rc=2
Also, depending on *why* you can't read the screen, it may be possible to force-change the current display setup back to something more useful using xrandr at the command line through your SSH session, but read the man page first as it isn't the simplest thing to use.
Well, xrandr shows the following (I filtered out the low-res settings;
| @20:34:37 CyllarusCentaur@chestnut | wd=/home/CyllarusCentaur | $ xrandr|grep 'Screen|DP-|HDMI-|3440x1440' | Screen 0: minimum 320 x 200, current 3440 x 1440, maximum 16384 x 16384 | DP-1 disconnected (normal left inverted right x axis y axis) | DP-2 disconnected (normal left inverted right x axis y axis) | DP-3 disconnected (normal left inverted right x axis y axis) | HDMI-1 connected primary 3440x1440+0+0 (normal left inverted right x axis y axis) 800mm x 334mm | 3440x1440 100.00*+ 84.96 49.95 | HDMI-1-2 disconnected (normal left inverted right x axis y axis) | DP-1-4 disconnected (normal left inverted right x axis y axis) | DP-1-5 disconnected (normal left inverted right x axis y axis) | DP-1-6 disconnected (normal left inverted right x axis y axis) | rc=0
which indicates that it is in its preferred (native) resolution.
(I won't be using xrandr to modify any of the zillion settings shown on the info page; hardware stuff makes my head hurt. :-) I never should have messed with Monitor & Display in the first place.)
