[SOLVED] MATE, dual displays and window list

[SOLVED] MATE, dual displays and window list

Postby MaineTim on Sat Jun 16, 2012 7:52 pm

Hopefully I'm just overlooking something here: I'm running dual displays (stacked on top of each other) and MATE's window list applet only shows windows located on the lower part of the desktop, where the panel is. How do I get window list to include windows on the upper display?

Thanks!

I don't know if it depends on wheter you have your displays as separate screens or the same screen (with something like twin view or those things).


Back in the times where I used dual display setup (sniff), with Ubuntu 10.10 (Gnome), if I had just one unique Window list in my panels, all my windows appeared there. If I added a new panel, moved it to the other display, and then added a Window List there, each list showed its screen's windows...


I think I used a TwinView setup, but I'm not 100% sure...


If that doesn't work, maybe you can workaround this by setting the "Show windows of all workspaces" in your Window list preferences...

Thanks for the suggestions. I should have said I'm running the Nouveau driver and the displays are set up to act as a single desktop using the "Monitor Preferences" utility that's bundled with LMDE/MATE. I've done this for years using the closed nvidia driver and twinview, as you described, with lots of other desktop environments, and it's always been fine. The current driver configuration works fine under Cinnamon.

Unfortunately, even the "Show windows of all workspaces" setting doesn't help. It still ignores windows in the upper display/half of the desktop. When I drag a window from upper to lower, it appears on the list, then disappears as it's dragged back up. MATE's Window Selector app (the one that pops up a menu of available windows, rather than displaying buttons) shows everything, but the Window List app only seems to see the half of the desktop where the panel is actually located.

EDIT: It turns out that there were several instances of window list running, with all but one being hidden while the panel "Expand" property was active. Disabling Expand, I could delete all the instances, add one back in, and set the Expand property again. All is now working as it should.
