From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Sometimes, my KDE starts without the "taskbar"

When I boot my Arch Linux machine, about 1/10 times the "taskbar" is missing. (Do you still call it a taskbar?)

All I see it desktop icons, the background and the mouse cursor. I'm using NVIDIA proprietary drivers.

Do you guys have any idea what's with that? It's hard to troubleshoot because it only happens sometimes.

It's the Plasma Panel.

It IS possible that this is the core of the problem, as historically NV has been a major PITA for Linux, especially #KDEPlasma #Wayland. Lately, i've read many peeps mentioning large improvements, but afaik it might still depend on your specific GPU HW model & driver version. I don't use NV, so cannot help directly on that, but i have some suggestions:

If your current Plasma session is Wayland, try logging in an X11 session. Or, vice versa.
It might be corruption of a KDE/Plasma config file. A quick easy initial test is to create a 2nd user account in Plasma, then log into that.
If that behaves correctly, it increases the probability of corruption [of your original user]. You can reset to default all those, via the following:

To backup existing plasma config:

cd ~/.config
for j in plasma*; do mv -- "$j" "${j%}.bak"; done

This command will rename all Plasma related configuration files to *.bak (e.g. plasmarc.bak) of your user and when you will relogin into Plasma, you will have the default settings back. To undo that action, remove the .bak file extension. If you already have *.bak files, rename, move, or delete them first.

To backup existing cache:

mv ~/.config/Trolltech.conf ~/.config/Trolltech.conf.bak
mv ~/.cache/ ~/cache.bak
mkdir ~/.cache
kbuildsycoca5 --noincremental && kbuildsycoca4 --noincremental

Good luck.
