*** If you're not sure this is actually a bug, instead post about it at https://discuss.kde.org If you're reporting a crash, attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** SUMMARY I could click on both password boxes to enter the password and login. The problem was solved by going to Display Configuration -> selecting the other monitor and disabling it. I will have to see whether the device always needs to be manually enabled after powered on or if it's enough to have it powered on only once when enabled. STEPS TO REPRODUCE 1. A second display is configured but powered off (it was probably disabled at the time and the upgrade seems to have enabled the device) 2. Upgrade to Debian12/KDE from Deb11/KDE 3. Show the lockscreen by waking from standby or by Log Out OBSERVED RESULT One small lockscreen above the other. EXPECTED RESULT Only one lockscreen even if mutliple display device are connected SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian 12 KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION
Are you using X11 or Wayland? Does it reproduce on both, or only one? Can you attach a phone photo that shows what it looks like when this happens?
I think X11 because Wayland had these problems where it turned to gray which solved themselves now and I intended to use Wayland and do use it now. I think I can't reproduce it now because the problem disappeared once disabling the other display in the Display Configuration. I can describe how it looked like: exactly the same lockscreen just smaller and in the left corner of the larger lockscreen without any borders. Entering the password or clicking something on one also does it on the other lockscreen. I tried reproducing it by enabling the other display again but the lockscreen is as it should be. I tried Wayland in Debian11 before with both screens before switching back to X11 after a while so maybe that created some configs that then caused problems,
So you're unable to reproduce the problem anymore?
Yes, I tried reenabling the powered-off second display and locking the screen as well as reenabling and resuming from Sleep (for the second try I had to move the mouse to make it enter the password in the password box). If it happens again, I'll comment here. I also mentioned this problem here https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1068780
Ok, thanks!
Okay it's occurring again now. I enabled the second screen again and this time after waking from sleep there were two lockscreens again. I think I tried resume from sleep with the other powered-off screen enabled before. Back then this didn't occur but it did occur now. Now I also tried locking the screen: it shows only one lockscreen. After resuming from sleep and moving the mouse in the larger lockscreen, the smaller lockscreen that showed in the upper corner on top of the bigger one disappears. I'm using Wayland now. I can also enter the password in the smaller lockscreen. I had plasmashell running from the kstart5 plasmashell command in the konsole and this is the output in the console that could be useful: > file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/PipeWireThumbnail.qml:11:1: module "org.kde.pipewire" is not installed > Could not find the Plasmoid for Plasma::FrameSvgItem(0x55be4a604ee0) QQmlContext(0x55be4763e640) QUrl("file:///usr/share/plasma/plasmoids/org.kde.plasma.notifications/contents/ui/global/Globals.qml") > Could not find the Plasmoid for Plasma::FrameSvgItem(0x55be4a604ee0) QQmlContext(0x55be4763e640) QUrl("file:///usr/share/plasma/plasmoids/org.kde.plasma.notifications/contents/ui/global/Globals.qml") > qt.qpa.wayland: Wayland does not support QWindow::requestActivate() > qt.qpa.wayland: Wayland does not support QWindow::requestActivate() > Checking screens: available: (QScreen(0xid1, name="HDMI-A-1")) redundant: QHash((QScreen(0xid2, name="HDMI-A-2"), QScreen(0xid1, name="HDMI-A-1"))) fake: QSet() all: (QScreen(0xid1, name="HDMI-A-1"), QScreen(0xid2, name="HDMI-A-2")) Initializing "/usr/lib/x86_64-linux-gnu/qt5/plugins/plasma/kcms/systemsettings/kcm_fonts.so" > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:20: TypeError: Cannot read property 'pluginName' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:75: TypeError: Cannot read property 'configuration' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:78: TypeError: Cannot read property 'pluginName' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:80: TypeError: Cannot read property 'configuration' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:81: TypeError: Cannot read property 'configuration' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:82: TypeError: Cannot read property 'configuration' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:83: TypeError: Cannot read property 'configuration' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:84: TypeError: Cannot read property 'configuration' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:16: TypeError: Cannot read property 'configuration' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:17: TypeError: Cannot read property 'configuration' of null > file:///usr/share/plasma/wallpapers/org.kde.slideshow/contents/ui/main.qml:18: TypeError: Cannot read property 'configuration' of null This seems to happen at every resume from sleep but if the mouse is located on the larger lockscreen once it is moved just slightly the smaller lockscreen disappears. Also it would be useful if the two displays have different resolutions and Unify screen rather than Extend screen is used (as now) the larger resolution is kept on the display with the larger resolution. If there's something I should test or some logs I should check, please let me know.
Now it also shows two lockscreens when I lock the screen. Maybe I moved the mouse a bit the last times I tried (if it's not in the corner of the small lockscreen the small lockscreen disappears once the mouse is moved)
Does it still happen in the upcoming Debian 13?
I just have the other screen disabled and have the Display Configuration in the task bar which makes it quick and easy to turn the other display on. Then this problem doesn't occur. I'm not sure if it still occurs, I would have to test but I did two tries of restarting from standby with the other screen enabled but turned off and it didn't occur so it's well possible that this problem has been solved.
