Thunderbird task manager icon

If you use Wayland and in taskbar TB has an ugly W icon, you can try

  • to check if the path of icon is correct;
  • add this line (or something similar) in tb .desktop file: StartupWMClass=thunderbird-esr. Instead of thunderbird-esr you could have to check the appropiate name of TB in yout system.
  • be sure that the name of your desktop file be capitalized, that is Thunderbird.desktop and not thunderbird.desktop;
  • be sure that you don’t have duplicate Thunderbird entries (i.g. in KDE menu or in .desktop files)

Linux KDE: add an app to the panel (no pin it)

To have an application (a program, such as Firefox, or Thunderbird) in your KDE desktop bottom bar, not as “pinned”, but as an icon, you can a) add to desktop that app, and then b) copy it (with the mouse) into the left part of the bottom bar (not in Icon only task manager, but at its left).

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-generic

linux 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:

  1. rules not memorized: to fix it check if configurations files (tipically in ./config/ kwinrc and kwinrulesrc) have the right permissions (avoid: non access).
  2. 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
