Here is a desktop recording showing the problem. Note: The screen recorder concatenates both monitors into one "super sized" rectangle. The primary monitor is the left half and the secondary monitor is the right half, with no visible separation. When icons appear on the 2nd monitor they show just to the right of the center of the recorded image.
For this vidwo I set the resolutions of both monitors to be similar, but you can see a narrow black rectangle under the primary monitor because it is set to slightly smaller vertical dimension than the other monitor. The primary mon is 1920x1080 and the 2nd monitor was 1920x1200 (it's native res). ** Description changed: In Settings->Desktop : Desktop Layout With "Show icons on all monitors" then icons only appear on the primary monitor. With "Show icons on non-primary monitor(s) only" the icons do appear on - the 2nd monitor as expected. This shows that the 2nd monitor is - recognized (besides, I can see the Cinnamon desktop image on the 2nd - monitor). + the 2nd monitor **but only** if "Show icons from missing monitors" is + checked (!) + + I'm not sure what "missing monitor" means. My graphics card has 3 + outputs (2xHDMI, 1 DP) and I'm using two of them, so there is an unused + output which might be called a "missing monitor". Anyway, I don't + think that checking this option should have any effect on whether icons + are ever shown on the second monitor (which is connected and working, + not missing). + + The "show on all monitors" option only ever shows icons on the primary + monitor, whether or not the 'missing monitors' option is checked. The monitors are different resolutions, if that matters. Primary (which is monitor #2, I guess because of the port being used): 3840x2160 Second (monitor #1): 1920 x 1200. "Join Displays" is selected. + I tried "Reset to Default" in Settings->Display->Layout but it didn't help. - - I tried "Reset to Default" in Settings->Display->Layout but it didn't help. + I'll attach a desktop recording showing the problem.
