[KScreen] [Bug 486374] New: External monitors not detected
https://bugs.kde.org/show_bug.cgi?id=486374 Bug ID: 486374 Summary: External monitors not detected Classification: Plasma Product: KScreen Version: 5.27.5 Platform: Debian stable OS: Linux Status: REPORTED Severity: major Priority: NOR Component: common Assignee: kscreen-bugs-n...@kde.org Reporter: g...@xod.ca Target Milestone: --- Created attachment 169056 --> https://bugs.kde.org/attachment.cgi?id=169056=edit Display Configuration showing only internal screen being detected Laptop : Asus Rog Strix G17 GeForce 4070 RTX Platform : Debian stable KDE Plasma 5.27.5 The 2 external monitors I'm plugging in, are not being detected even though they work with my Windows laptop. An AOC C24G1A (HDMI) and a Samsung monitor (DisplayPort). I also ran Nvidia's Linux driver, which installed their "Nvidia X Server Settings" app which didn't make any difference except that now when I reboot, the login screen shows up on the HDMI monitor (but it goes blank again after I've logged in). -- You are receiving this mail because: You are watching all bug changes.

[plasmashell] [Bug 353975] Black screen on second display (no wallpaper, can't get a context menu on right-click)
https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #232 from gene c --- (In reply to Nate Graham from comment #230) > (In reply to gene c from comment #228) > ... > have to lose customizable desktops, customizable panels, desktop widgets, > desktop icons, and so on... Hiya Nate - yeh sorry I wasn't terribly clear, let me try expand a bit. In above I was simply referring to their method of identification / tagging of monitors in multi display setting and not the DE philosophy around what can be customized. I've not gone over code for either DE, so I could well be missing something - but the problems here seem at least partly related to correctly identifying and tagging monitors, which I would not have guessed would impact customization. But hey, what do I know ... :) If indeed some customization were lost, say different backgrounds on different monitors or whatever, but things otherwise work - yes that would 100% be preferable to more flexible but not working. But absent detailed knowledge of the code, I would have guessed that customizing and display tagging are largely mutually orthogonal. Anyway, thanks. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #228 from gene c --- Kind of obvious question: since gnome is working extremely well, and is open source, have kde devs looked at gnome code to see what they do to handle multiple monitors with a view to potentially follow their methodology (with appropriate attribution etc)? Assuming of course, as some may have suggested, that there is an algorithmic weakness rather than a sound approach that is just buggy in plasma. But if the kde approach is flawed, then gnome may help light a path forward? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #209 from gene c --- I found a work around that works fine - i installed gnome (yes I know) and if kde every gets to a usable state can always use gdm to launch plasma. gdm is native wayland and seems more stable than sddm which also helps. not ideal for sure but based on @nate's indicated time frames, sounds like this won't be fixed until 2023, which is a little too long for me. I'll keep an eye out but for now plasma is just not usable. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #202 from gene c --- Indeed it is quite disheartening that a bug of this obviously very high importance sees no feedback. Neither this or 450068 have been assigned - so that means no-one is working on it. Really hate to switch back to gnome but best I can tell at least multi monitor set up works there. @Nate - can you please provide a time frame for when this awful bug might be (a) worked on and (b) fixed? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #199 from gene c --- If I use kcm to split the displays into 2 (left and right) plasmashell the plasmashellrc doesn't change - and it crashes shortly after hitting apply and backgrounds go black and its back in mirror mode again. Both displays are labelled the same in the settings as mentioned above which seems odd obviously. On other hand my laptop with a single USB (DP) monitor works fine - of course these are always distinguishable so perhaps makes sense. -- You are receiving this mail because: You are watching all bug changes.

[ScreenConnectors] 0= 1=DP-2 2=:0.0 The behavior after 5.25.4 - now after screen lock is woken up - both monitors show same info (mirror mode) - after fiddling (a lot) can convince it back to 2 monitors - then it happens again. The above is the state reflecting mirror version. If its helpful I can try get dual monitors working again and then resend if its any different. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #173 from gene c --- I can regularly crash plasmashell by simply editing (1 of the 2) panel and adding (or trying to add) applications from kmenu - not convinced this wasn't commonplace in released version though. I did this as after updating to 5.24.90 all customized panel settings were lost. i gave up after multiple tries, added default panel and use quick launcher now - which at least don't crash and vanish :) This is beta and bugs are expected. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #170 from gene c --- Hi @Nate: Results of testing with Archlinux 5.24.90 from kde-unstable repo. Good: - Both monitor desktops continue to work after idle and wake cycle (yay) which means the major bug is fixed. Bad (ish): - After idle/resume all windows are pushed to 1 of the 2 monitors. This has one usb-c and one hdmi - so feels like timing issue to me - Tons of messages logged to journal - plasmashell[xxx]: IPDL protocol error: Handler returned error code! plasmashell[xxx]###!!!

https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #160 from gene c --- Since restarting plasmashell always "fixed" the desktop I don't think your test validates that anything is fixed. I suppose there are 2 possibilities: (i) If the crash is a result of the "fix" and now crashes instead then bug is not fixed. (ii) Crash is unrelated, so cannot tell if the bug is fixed or not yet (bad build, new bug, etc). Either way, until it stops crashing we cannot tell which of the 2 is happening. Has anyone else managed to get git master fully built with all deps updated etc and test it? -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=353975 --- Comment #135 from gene c --- Reporting back - with no screen lock at all - problem persists. And same with sddm or lightdm. Clearly seems related to powering off and resuming of monitors for our case anyway. I suppose since gdm is wayland capable while sddm and lightm both use X - that could be playing into this. Curious that a new display manager like sddm is built solely on old X technology instead of wayland come to think of it. -- You are receiving this mail because: You are watching all bug changes.

If I leave the plasma wayland session - then the plasma locker kicks in and things are once again broken. So this tells me that is the trigger/source of the problem.
