Bug ID: 491868 Summary: Black screen on external display (no wallpaper, no icons, can't get a context menu on right-click) Classification: Plasma Product: plasmashell Version: 6.1.3 Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: oleg.g...@gmail.com CC: k...@davidedmundson.co.uk Target Milestone: 1.0 SUMMARY This issue is a follow-up to this one: https://bugs.kde.org/show_bug.cgi?id=487134 with some minor differences. I run KDE on a laptop with external display connected over HDMI. Built-in display is disabled in "Display Configuration" and external display is configured as the only one enabled. After boot -> startx -> logout -> startx sequence black screen is shown on external display. No wallpaper, no icons, can't get a context menu on right-click. Only task panel is visible and usable. It happens randomly but pretty consistently. As a workaround I use the following command which restarts plasmashell and then everything is OK again: kquitapp6 plasmashell && kstart plasmashell & There are no errors in journal related to KDE, only some warnings but it is hard to tell if any of those are relevant to this issue. Let me know if any particular logs can help investigate the issue. STEPS TO REPRODUCE 1. Have a laptop and external display 2. Connect external display over HDMI 3. Using "Display Configuration" disable built-in display and enable only external one 4. Reboot 5. KDE is loaded correctly via startx 6. Log out 7. startx OBSERVED RESULT Black screen. EXPECTED RESULT Wallpaper and icons.
