When the screens turn off (after some time) and turn on again, the panels of the screens are switched. Running "kquitapp plasmashell" and "plasmashell" fixes the problem. One of the screens takes a few seconds longer to start again, this may be related to the problem. 1667941 1 notmart 2017-03-23 17:12:25 +0000 is the screen that's switched off marked as "primary"? 1667942 2 notmart 2017-03-23 17:12:40 +0000 maybe related with https://bugs.kde.org/show_bug.cgi?id=377588 1668031 3 mtijink.bugs 2017-03-24 08:45:20 +0000 Both screens switch off, but the primary screen indeed takes a bit longer to turn on again. I don't know if the other bug is related. I do have "lastScreen=0", 1 and 2 in plasma-org.kde.plasma.desktop-appletsrc (there's also a laptop screen which is turned off), but the system starts fine. The problem only occurs after the screens are turned off (by the energy saving settings). 1670234 4 notmart 2017-04-06 12:42:03 +0000 energy saving shouldn't change screen configuration in any way... 1754107 5 jordanleppert 2018-05-22 09:04:37 +0000 What graphics card, and driver are you using? And what kind of connection to the screens (DVI, DisplayPort etc)? I have this issue and wondered what the common element is. My setup: * Kubuntu 18.04, 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) 1754198 6 matthijstijink 2018-05-22 18:00:03 +0000 I don't have the same setup anymore, so don't experience the issue anymore. But, for the record: - Arch Linux packages - Nouveau driver, unknown graphics card - The setup was: one hdmi-connected monitor, and the laptop screen. Although it also occurred when I added a vga-connected monitor. - The right screen was indeed set as the primary screen (the hdmi-connected one). 1754212 7 jordanleppert 2018-05-22 18:22:55 +0000 Thanks, NVidia GPUs seem to be a common element (I mean, they're pretty popular obviously but even so). 1883665 8 germano.massullo 2019-10-04 20:34:04 +0000 Is this bug still happening on newer Plasma versions? 1883720 9 matthijstijink 2019-10-05 10:09:35 +0000 I don't have the same setup anymore, so I cannot try to reproduce. 1883723 10 jordanleppert 2019-10-05 10:30:36 +0000 Yes, this is happening with: Plasma 5.16.5 KDE Frameworks 5.62.0 Qt 5.13.1 I'm using an AMD Vega 64 GPU and running Arch. 1883724 11 jordanleppert 2019-10-05 10:33:30 +0000 For me though, the panels aren't so much switched, but both screens show the window list for the right hand desktop (I have the window list setup to show windows on the current screen). Both my panels are identical so I can't tell if the whole panel has been duplicated. I'm getting around this by having a constant python script running in the background that detects when the screens have been switched off and back on, and automatically restarts Plasma. 1883725 12 jordanleppert 2019-10-05 10:35:23 +0000 More relevant info: I have two 4k monitors connected with DisplayPort 1.2. 1886646 13 bug-janitor 2019-10-20 04:33:10 +0000 Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days.

I have two external monitors connected to my latop. I disable the screen of my laptop. I add panels to every monitor and everything works fine until I unplug the monitors and plug them again. It seems that there is no kde desktop conf for every monitor saved. Is this right? I do not know if there is a but of we need a feature for that. Thank you very much. 1890413 16 nightelf7 2019-11-08 07:43:00 +0000 Sory I forgot to mention that I am using Kubuntu 19.10 with backports and KDE 5.17.2 but the problem was the same with KDE 5.16.5. I thoght that the upgrade might fix this problems but it was not the case. 2053798 17 nate 2021-08-16 23:06:50 +0000 *** This bug has been marked as a duplicate of bug 356225 ***
