Problems with Plasma 6

In KDE Neon the upgrade to Plasma 6 has produced several problems:

  • No working power commands (logout, restart, shutdown): this could be a problem from espanso (a text expander for Wayland). Try to stop it (espanso stop) and, if so, create a logout script.
  • applications as root from menu don’t work: you can use a code like this (it’s an example):
[Desktop Entry]
Comment=Twin-Panel File Manager
Exec=pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY KDE_SESSION_VERSION=5 KDE_FULL_SESSION=true krusader
GenericName=File Manager
Icon=krusader_user
Name=Krusader-root
NoDisplay=false
Path=
StartupNotify=true
StartupWMClass=krusader
Terminal=false
TerminalOptions=
Type=Application
X-DocPath=krusader/index.html
X-KDE-SubstituteUID=false
X-KDE-Username=root
  • reimage service menu (in Dolphin) could not work; to fix it try with this:
 sudo mv /usr/share/kservices5/ServiceMenus/reimage* /usr/share/kio/servicemenus/

Ugly icons in KDE Plasma 6

The simplest way to get the right icons is to choose breeze as main theme, and then go (as root, ui.g. with Krusader in root mode) to usr/share/icons and rename breeze/places to places.orig, and afterwards symlink places from Humanity Classic to breeze.
To get correctly Humanity Classic you have to install (via Synaptic) Adwaita icons, otherwise you could be forced to remove a lot of essential packages. Installing Adwaita will ask you a very small kind of change.

Replacing Autokey in Wayland

Many Linux distros are leaving xorg (x11) for Wayland, as display server protocol. Unfortunately not all the applications are ready for Wayland.

In particular Autokey, a very useful application to expand text and automatize typing operations, is not (yet) compatible with Wayland.

A quite good replacement of Autokey is Espanso. But there are also some limitations:

  • Espanso has big problems in LibreWriter (abbreviations are often expanded with errors). Similar problems there were also with Autokey in LibreWriter, but Autokey was able to provide some workarounds.
  • Espanso, unlike Autokey, can provide a very small range of hotkeys (such as ctrl + alt + d): Espanso can use only hotkeys with ctrl (not with alt or shift) and a few letters. I.g. “x01” means “ctrl + a”. You can find the whole range of possible combinations here.

However, as long as the main typing operations are in LibreWriter, or Kate, you can use that applications possibilities to expand text.

in LibreWriter there are at least two possibilities (to expand an abbreviation):

  • tools – > autocorrect
  • tools -> autotext

In Kate you can use snippets to create something similar to Autokey.

I.g. to create a snippet to wrap selected text with the tag <h1>, you can add this code as snippet code:

${rangeCommand("<h1>%%1</h1>", "title")}

Choose the title as you prefer (obviously without spaces), and a key combination, i.g. ctrl+1.

Don’t forget to add, in the javascript section (the tab scripts) this code

function rangeCommand(command, def) {
    if (view.selectedText().length > 0) {
        return command.replace("%%1", view.selectedText());
    } else {
        return command.replace("%%1", def);
    }
}

In this way, you will be able to add a title <h1> to your selected text.
