Forgot to add, the bug also affects other actions on the desktop, like mouse wheel scrolling from one virtual desktop to another. Windows can still be placed on the second monitor, and changing the virtual desktop via keyboard shortcut/first monitor wheel scroll/panel widget works and show the switching animation. If it matters, I'm running nvidia 340xx proprietary drivers. It's definitely the plasmashell process where the bug happens, killall plasmashell && plasmashell fixes the missing desktop. I can confirm this behaviour too. After fresh reboot of a laptop connected to an external monitor (directly or via docking station makes no difference) the external display goes blank after login to kde, however randomly, the laptop display instead goes blank. Before login to kde both displays are showing the login-screen. Also, while the laptop screen is blank, if closing and opening the laptop lid the plasma desktop seems to be restarted and both the external and the laptop display shows the desktop for a while before triggering a crash of plasma desktop. I have noted in the system settings "Display Configuration" that the external monitor is only randomly detected, while using xrandr it is always detected. Running xrandr --auto seems to always produce output on both screens. Plasma 5, kscreen and xrandr does not seems to play nice together!? KDE plasma 5.4.1 Kernel 4.1.10-200-fc22-x86_64 Intel i7-5600U I confirm the bug on Plasma 5.4.2 and Qt 5.4.2 After connecting second monitor to my laptop (Haswell Intel graphics) the plasma shell just moves to the external monitor and black background remains on the laptop display. xrandr output after connecting second monitor Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767 eDP1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 309mm x 173mm 1920x1080 60.05*+ 59.93 48.04 1680x1050 59.95 59.88 1600x1024 60.17 1400x1050 59.98 1280x1024 60.02 1440x900 59.89 1280x960 60.00 1360x768 59.80 59.96 1152x864 60.00 1024x768 60.00 800x600 60.32 56.25 640x480 59.94 DP1 disconnected (normal left inverted right x axis y axis) HDMI1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 531mm x 299mm 1920x1080 60.00*+ 1280x1024 60.02 1440x900 59.90 1280x800 59.91 1152x864 75.00 1024x768 70.07 60.00 800x600 60.32 56.25 640x480 66.67 60.00 720x400 70.08 HDMI2 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) Can anyone confirm this with Plasma 5.17 or the 5.18 beta? I have not encountered the bug for some time (using both 5.17 and 5.14 Plasma versions) Oh good! |
