In Linux you can use these commands:
- sudo apt autopurge nvidia
- sudo apt autoremove
- sudo apt-get install kde-plasma-desktop
nvidia grafical card and linux kernel
It could happen that a new kernel doesn’t work with your nvidia (geforce) grafical card. The problem could de the linux-modules, such as linux-modules-nvidia-460-5.8.0-53-generic.
You can check it by the following command
dpkg --list | egrep -i --color 'linux-image|linux-headers|linux-modules' | awk '{ print $2 }'To solve this, if you find that the last kernel does’t have a matchintg nvidia module, you have to install manually that module
sudo apt-get install linux-modules-nvidia-460-5.8.0-53-genericlinux black desktop
It’s a bug which affects only one user and not the whole graphical desktop, but only the “desktop” in a narrow sense.
A workaround can be to rename the .config folder (to something like .config.old) so that you can get anew your whole graphical desktop and then maybe you could copy (prudently) one by one your config files (from .config.old to the new .config folder).
windows issues
In KDE Linux it could happen some issues with windows:
- rules not memorized: to fix it check if configurations files (tipically in ./config/ kwinrc and kwinrulesrc) have the right permissions (avoid: non access).
- new window below others already active: such as Clementine’s window, called from system tray, going below other windows; to fix this you have to set Focus stealing prevention in Window Behavior (the first tab of Window management in System settings) to none, as you can see in the image
