i just discovered that this bug also works in reverse ^^ if i just ignore the black desktop on one of my screens (that means i continue working without restarting plasmashell) the next time the screens go to sleep and i wake them up again desktop backgrounds are and contextmenu are back.... i wasn't sure at first but i've reproduced this 4 times now..... +1, Kubuntu 16.04 with kubuntu-backports repository. +1, ArchLinux with plasmashell 5.7.3 workaround1: pkill plasmashell; plasmashell & workaround2: disable/enable primary/secondary monitor and change primary monitor to each other and back again I recognized the problem at random logins. my secondary desktop moves to the primary monitor, secondary desktop stays empty/black - but is usable, you can move programs onto it. Desktop of primary monitor is gone. re-tested with kde neon on kubuntu plasma: 5.8.0 Qt: 5.7.0 the onlything new is that sometimes only the wallpaper is gone but the contextmenu is still there, adding a widget gets everything back to normal.. also when one of the screens went black the last time plasma seemed to restart automatically after 2 or 3 seconds.. what can i do to narrow down the reason for this ? i want this bug gone! yet another interesting observation: i added clock widgets to the screens... one of the screens went dark after sleep (no background - no rightclick contextmenu) but the widget remained visible (it still displayed the time when the screens went to sleep) i dare to say that this problem is fixed now by changing my own hardware setup. what i had: 1x hdmi out (connected to the hdmi port of my first display) 1x dvi out (connected to the hdmi port of my second dislay <dvi to hdmi cable>) what i have now: 1x hdmi out (conneted to the dvi port of my first display) 1x dvi out (connected to the dvi port of my second dislay) my screens went to sleep at least 5 times now without any problems... attention!! this bug is not fixed ! it just seems to work for my current (new) setup now. I can see this on KF5 5.27/Plasma 5.8.1 - it does not happen as often as in the past but the bug is still there. Restarting Plasma usually helps. I can provide config files if needed but it's difficult to explain the behavior aka what I did. It's just not there. There's still something strange going on in 5.8.2. After changing my screen setup - unplugged external monitor or switched over to another hdmi port - I get a default background at the next boot on my secondary monitor. So the wallpaper and the widgets are reset. primary monitor stays normal. I have a laptop and external screen, My laptop screen has my taskbar and both desktops have the same background. When my computer wakes from sleep, sometimes the laptop screen is black and I am not able to right click and assign a background again. Restart fixes the issue Plasma 5.8.2 Debian Stretch i can confirm that in plasma 2.8.90 frameworks 2.28.0 Qt 5.7.0 this bug is still unresolved. it just changes a little bit... kquitapp5 plasmashell ; /usr/bin/plasmashell --shut-up brings back my messed up icons in the panel (different bug) but this time screen number 2 stays black.. so it keeps the problem alive now even if i kill it ! btw. why is this bug still "unconfirmed"? is there no developer with a multiscreen setup experiencing the same thing? ok.. it seems this bug is fixed in 5.8.4 I can confirm that, no more issues in 5.8.4 |
