(Unsure if this is considered a duplicate of Bug #361144 as the state it resets to after a reboot is slightly different. If it is a duplicate please mark it as so.) Upon rebooting, display configuration of dual monitors (extended display, not clone) is lost when set through kscreen. While both displays are still enabled after a reboot orientation, choice of primary display and secondary display wallpaper are incorrect and must be reconfigured. Reconfiguring will cause settings to persist until system is rebooted at which point the settings are reverted again. System specifications: KDE Plasma Version: 5.8.2 KDE Frameworks Version: 5.27.0 QT Version: 5.7.0 OS: Arch Linux x86_64 GPU: Intel® HD Graphics 2000 (modesetting driver in use) Display server: Xorg Reproducible: Always Steps to Reproduce: 1. Configure dual screen layout with kscreen (either through kcm or "Displays" module) 2. Reboot system (either through Plasma menu or "sudo reboot") Actual Results: 1. Display configuration is lost and must be reconfigured Expected Results: 1. Display configuration persists My monitors are connected to the motherboard's onboard VGA and DVI ports, not though a PCI/PCI-E graphics card. Could this possibly confuse kscreen when it detects the displays? I am unable to test on Wayland at the present time as there are issues which leave Plasma unusable on my particular setup. Attempted fixes: - Deleting all files in ~/.local/share/kscreen, rebooting and reconfiguring - Configuring through seperate "Display" window as opposed to kcm module

Issue persists in Plasma version 5.8.3.
Not sure I understand correctly, but you say that the position of the displays is fine after reboot, just that the wallpapers are swapped around? Could you compare the output of kscreen-doctor -o in both situations and tell me the difference? (This smells like a bug which we've just fixed in plasmashell yesterday.)
Apologies, I should have made myself more clear. Upon rebooting my system, the following configuration values are lost: - Primary screen selection (where main panel resides) - Display orientation - Primary display wallpaper However, it appears that since I have installed KDE Applications 16.08.3 the issue has been resolved. I have tested my system on multiple reboots and my display configuration is persisting. I will attach the kscreen-doctor output of my last reboot. However, this is of a reboot where the issue has not occured. If I do get a reboot where I can replicate the issue, I will post the kscreen-doctor output again.

Here is the output copy and pasted from Konsole) Output: 65 VGA-1 enabled connected primary VGA Modes: 71:1280x1024@60! 72:1280x1024@75* 73:1152x864@75 74:1024x768@75 75:1024x768@60 76:832x624@75 77:800x600@75 78:800x600@60 79:640x480@75 80:640x480@60 81:720x400@70 Geometry: 1280,0 1280x1024 Output: 66 HDMI-1 enabled connected HDMI Modes: 71:1280x1024@60! 72:1280x1024@75* 73:1152x864@75 74:1024x768@75 75:1024x768@60 76:832x624@75 77:800x600@75 78:800x600@60 79:640x480@75 80:640x480@60 81:720x400@70 82:1280x960@60 83:1024x768@70 84:800x600@72 85:800x600@56 86:640x480@73 87:640x480@67 Geometry: 0,0 1280x1024 Output: 67 DP-1 disabled disconnected DisplayPort Modes: Geometry: 0,0 0x0 Output: 68 HDMI-2 disabled disconnected HDMI Modes: Geometry: 0,0 0x0 Output: 69 DP-2 disabled disconnected DisplayPort Modes: Geometry: 0,0 0x0
After multiple reboots with the affected system I am now no longer able to replicate my issue. It seems that KDE Applications 16.08.3 may have fixed it for good. On each boot my system retains the screen layout and settings from the previous session. Can I close this as "RESOLVED" or would you prefer it be left open for now?
Closing it, if necessary, bugs can easily be reopened. Thanks for the heads-up!
No problem. Closed.
