Hey everyone, I can verify issues with multi-monitor setups when screens are overlapping/mirrored. I usually avoid this by working with independent screens as well.
With XINERAMA support in dwm you can dynamically configure monitors via xrandr. If you configure them to coincide, e.g., `xrandr --output <display2> --auto --same-as <display1>`, it seems that at least for some configurations dwm creates separate `Monitor` structs unconditionally and you can cycle through the monitors via shortcuts. But because they overlap you will not even see the bar for one of the monitors and window management is screwed up as well. Notice that there is actually logic in the code that should prevent this for the case where virtual screen positions coincide. (`isuniquegeom`) Along the same lines of code I recently noticed that dynamically adding an independent/unique screen via xrandr can change the Monitor->physical screen association and thus move all existing windows to a different physical screen. Maybe it's a different bug altogether though, I did not have time to investigate. v4hn On Fri, Nov 12, 2021 at 09:18:22AM +0100, Laslo Hunhold wrote: > On Thu, 11 Nov 2021 19:34:08 +0100 > Thomas Oltmann <thomas.oltmann....@gmail.com> wrote: > > Dear Thomas, > > > What do I do about this? > > Is it even a bug or just me using dwm for stuff it's not intended to > > do?
