Hello, My system is afflicted by the "monitor not enabled after hot-connect" bug [BUG]. This was previously discussed on Debian lists [DEBIAN]. I have done a bit of debugging and applied a fix locally that simply sets the enabled flag to true on each connected display. This completely resolves the issue for my case. I reported this in the upstream bug report but there was no reaction. However, there was a note in the bug report stating that while no KDE developer has been able to reproduce the issue (!) but there was recently a "massive multiscreen overhaul" merged into upstream on 2022-12-15. My understanding is that this will be in the 5.27 release. I tried getting upstream sources for 5.27 suggested by Nate Graham [BUG2] but quickly got overwhelmed by the need to re-build more than just the five he listed. Thus, I'm wondering whether there's an easier way for me to try 5.27 packages. I'm completely intimidated by the set of KDE packages in Debian. So I'm curious whether there is any thought that 5.27 might be uploaded anytime soon. Finally: I can confirm that the bug remains present in yesterday's upload of kscreen 5.26.5. And for completeness, I am including my patch for any interested. Thanks, -Steve [BUG] https://bugs.kde.org/show_bug.cgi?id=460341 [BUG2] https://bugs.kde.org/show_bug.cgi?id=460341#c96 [DEBIAN] https://lists.debian.org/debian-devel/2022/10/msg00271.html https://lists.debian.org/debian-kde/2022/10/msg00042.html
