When i upgraded to 5.8 all widgets/panels from my left (primary) monitor get moved to the right (secondary) monitor after reboot. Secondary monitor is not even on. Some widget settings also reset like panel being able to go behind window. Reproducible: Always Steps to Reproduce: 1. Place widgets/panels on the primary (left) screen 2. Reboot Actual Results: Widgets/panels end up on secondary monitor that is also turned off. Expected Results: Widgets should remain on the screen they were placed on. Similar issue existed on 5.7, however it was the other way around: widgets/panels moved to secondary screen were moved back to primary screen upon reboot. Screens are placed one next to another: [DVI-0 2560x1080][VGA-0 1920x1080]
Okay guys i value all the hard work you put in but this is simply nuts. To avoid this bug i disabled my (right) screen. You know what happened after reboot? All my widgets gone. Guess where they end up. That is right - on the second screen! I had to enable screen again, turn it on and get back widgets to primary screen. Not only this breaks multiscreen support - there is no way to get out of this. Fix is needed most urgently. Not sure how many people have patience to deal with these kind of things...
Switching from Archlinux testing repositories to stable fixes issue apparently.
Victory sounded too soon. Next day issue is back. Not sure what made it go away briefly. Tried rebooting with secondary monitor both on and off - same result. This is very frustrating.
Using 5.8.1 at the moment, this no longer happens for multiple days, which is great. However secondary monitor upon boot always has wallpaper reset and cashew displayed and i have to turn it off every time. Could this be same problem and be like failing to save configs somehow?
I think I have the same issue.
Plasma panel also jumps to the wrong screen when I run kquitapp5 plamashell && plasmashell
I see the same issue, only it happens after locking and unlocking the screen.
(In reply to beojan from comment #7) > I see the same issue, only it happens after locking and unlocking the screen. But only after leaving it for a while it seems, so I can't just lock and unlock again to get things back the way they were.
Same thing happens to me. I turn monitors on/off (I have 3) and widgets/panels move between the 3 of them as if plasma forgot which screen was which. I love KDE, but the multi-monitor support is very unstable.
Oh.. and I'm on KDE Neon plasma-desktop 5.12.3-0neon+16.04+xenial+build84
I also have this issue on Kubuntu 18.04. I "got around" it by just adding exactly the same panel config to each screen. Which works for now, but I'll be moving to a different distro and DE soon if this isn't fixed, because it seems to be causing other issues such as this one: https://bugs.kde.org/show_bug.cgi?id=394532 My setup: * Kubuntu 18.04 64-bit, all updates as of 21-MAY-2018 * Nvidia GTX 980Ti, using proprietary driver nvidia-driver-390 (390.48) * Two 4k monitors connected via DisplayPort * The right-hand screen is set as the primary screen (in Plasma settings and in NVidia settings)
Is this bug still happening on newer Plasma versions?
I'm not experiencing it on reboot. Only when the screens turn off and back on.

What seems to be happening is that the mapping of containments to screens is getting corrupted. This could cause the screens to show different panels/widgets/wallpapers from what they are supposed to show, or to show no panels/wallpapers/widgets at all.

People who are affected: can you open your ~/.config/plasmashellrc file and paste everything under [ScreenConnectors]? I'm starting to suspect that basically all of these issues are caused by Bug 450068.

Intel DDX driver omits xrandr hyphens. Intel DDX, Radeon DDX & AMDGPU DDX drivers indicate DisplayPort instead of DP. I have not determined what situations replace DVI-I-1 with DVI-A-1 or DVI-D-1. Multi-Stream Transport (MST) & docks make a mess of xrandr name predictability.
(In reply to Nate Graham from comment #25) > People who are affected: can you open your ~/.config/plasmashellrc file and paste everything under [ScreenConnectors]? I'm not affected regularly by this bug but quiet recently the all widgets and the wallpaper of two secondary screens just swapped places: ``` [ScreenConnectors] 0=DisplayPort-1 1=HDMI-2 2=HDMI-A-2 3=DP-1 4=HDMI-A-1 5=:0.0 6=HDMI-A-0 ```

Thanks for the data, everyone. Based on what I can see there, you're all experiencing the same basic issue of connector IDs being volatile, especially for DisplayPort monitors. This is a design issue that needs to be fixed by changing the mapping of monitor to desktop to use something more stable. This work has started to be scoped out, and may optimistically land in Plasma 5.26. If not that, then 5.27. *** This bug has been marked as a duplicate of bug 450068 ***
