SUMMARY After every login, my second monitor is always disabled. Enabling it in the display settings fixes the issue for the current session. However, after restarting my computer and logging in again, the second monitor is again disabled. If merely logging out and back in without restarting, the second monitor stays enabled. STEPS TO REPRODUCE 1. Start the PC 2. Log in 3. Enable both monitors 4. Restart the PC 5. Log in 6. Observe how the second monitor is disabled OBSERVED RESULT The second monitor is always disabled after restarting the PC, regardless of the display settings. EXPECTED RESULT The second monitor should be enabled whenever it has been enabled in the display settings. SOFTWARE/OS VERSIONS Linux/KDE Plasma: EndeavourOS (Arch Linux) Kernel 6.0.1-arch2-1 / KDE Plasma 5.26.0 Wayland KDE Plasma Version: 5.26.0 Wayland KDE Frameworks Version: 5.99.0 Qt Version: 5.15.6 ADDITIONAL INFORMATION The bug only shows up in KDE Plasma. In the SDDM greeter, the second monitor is always enabled.
If you remove the contents of .local/share/kscreen and reboot the computer, is the second screen still disabled on startup? (make sure to make a backup of .local/share/kscreen before testing this)

Thank you for your reply.
