Something is really, really bad with your system. I just checked, creating new user works as expected, a logged in, then new/default Plasma config was created with default panel and wallpaper. I'm using the same distribution (KDE Neon 5.19). Maybe something is not correctly updated? Please run: sudo apt update sudo apt full-upgrade I have no idea what can be wrong. Hi Konrad, Thanks for the reply. My system is fully updated with no broken packages. I did try a reïnstall of all KDE package with the following commands: find /var/cache/apt/archives/ -name "*5.19.2*" | xargs sudo dpkg -i --force-overwrite --refuse-downgrade find /var/cache/apt/archives/ -name "*5.71.0*" | xargs sudo dpkg -i --force-overwrite --refuse-downgrade find /var/cache/apt/archives/ -name "*5.14.2*" | xargs sudo dpkg -i --force-overwrite --refuse-downgrade This made no difference, unfortunately. Deleting ~/.cache and ~/.config completely make no difference either. Do you have any clue whatsoever where I should be looking for the problem? Jeroen I found some errors in plasmoidviewer_systemtray, like: QIODevice::read (KCompressionDevice): device not open and series of "Cannot read property 'xxxx' of null" - that should not happen. I need more detialed logs, can you run this? QT_LOGGING_RULES="*=true" nohup plasmoidviewer --applet org.kde.plasma.systemtray Created attachment 129791 [details]
plasmoidviewer org.kde.plasma.systemtray
Here's the output.

Please see attachment. The file was to big (8,8Mb) so I compressed it. I found suspicious file: /usr/share/plasma/plasmoids/kpluginindex.json Remove or move it somewhere else and check again. Did you run Plasma as root? Probably this is duplicate of Bug 389297 (In reply to Konrad Materka from comment #7) > I found suspicious file: > /usr/share/plasma/plasmoids/kpluginindex.json > > Remove or move it somewhere else and check again. > > Did you run Plasma as root? > > Probably this is duplicate of Bug 389297 After moving this file to .bak, my systray is back again. I have never run plasma as root, this happened after the update from 5.19.0 to 5.19.1. Maybe an issue with the .deb packages? I cannot thank you enough for helping me, you really saved me! Thank you! Good to know it helped. Unfortunately I don't know what caused it - was it broken package or something else. I have the same distribution and it works correctly. If you want you can investigate further: * This will show if file belongs to any installed deb package (probably not): dpkg -S /usr/share/plasma/plasmoids/kpluginindex.json * Was the file created recently or long time ago? * Is it in compressed format or plain JSON text? Probably a text, which suggests it is a very old, not it is compressed. * What are the privileges to the file. Is it root:root 644 (-rw-r--r--)? Probably we won't know but it is worth to check, maybe someone else will stumble on this bug with an idea.

After moving the file to .bak fixed the issue, I removed it. I do remember the file command saying it was a bzip2 compressed file and owned by root. But that's all I have for you. |
