Edit: I’m glad so many of you have had no issues with multiple monitors. My set up is a little unusual (3rd display is an infrequently used large tv hooked through the receiver) and is definitely solveable but will take some effort (and honestly, I’d rather spend my spare time outside or with friends, so who knows when I’ll fix it.)
My 3 monitor setup has been really fantastic after switching to Cosmic desktop. Really really loving the mix of tiling and non-tiling features too.
Tangential to OP but just wanted to throw Cosmic out there for folks who haven’t yet tried it.
Didn’t realize Cosmic went 1.0 in December. How is it? I tried it a few months ago and really liked the tiling features and overall feel, but it was still a bit rough around the edges.
Tbh I have no real complaints. I would eventually like some keyboard shortcuts for moving entire workspaces around without the mouse, but what is there is quite intuitive and I find myself not leaving the keyboard to navigate. The defaults are similar to i3 shortcuts.
I like that they work in tiling and non-tiling mode, and each workspace can be set to either mode at whim.
No issues with stability (which was a problem for me in earlier builds).
I don’t use any of the Cosmic utils, though (text editor, terminal, etc). They seem fine but ymmv.
Edit: actually just thought of one thing… If you move a window from a non-tiling workspace to a tiling one, it stays in non-tiling mode. This leads to a mixed mode workspace and I don’t like that. But it’s easily fixed with mode toggle and only a minor annoyance – ideally I want it to switch to whatever mode the workspace is in.
