How to set my preferred font for monospace?

Having a good default monospace is important for a good UX in some Qt apps, especially terminal emulators and code editors. With LXQt ≥ 2.4, it can be set in LXQt Appearance Configuration → Font → Monospace. But the following method can be used everywhere. It overrides LXQt settings too.

Supposing that you prefer DejaVu for monospace (replace it with another font otherwise), create ~/.config/fontconfig/conf.d/0-mono.conf as:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
 <!-- To fix monospace: -->
 <alias>
  <family>monospace</family>
  <prefer>
   <family>DejaVu Sans Mono</family>
  </prefer>
 </alias>
 <alias>
  <family>serif</family>
  <prefer>
   <family>DejaVu Serif</family>
  </prefer>
 </alias>
 <alias>
  <family>sans-serif</family>
  <prefer>
   <family>DejaVu Sans</family>
  </prefer>
 </alias>
</fontconfig>

Note that it may not be a good idea to do this inside a global place (e.g., /usr/share/fontconfig), as different users may have different preferences.

How to fix colored emojis that are in black and white?

Some fontconfig tricks might be needed to get colored emojis (→ https://github.com/lxqt/qterminal/issues/627).

Supposing that you have installed a font like noto-fonts-emoji, create ~/.config/fontconfig/conf.d/0-emoji.conf as:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
 <!-- For colored emojis: -->
 <match target="pattern">
  <test name="family">
   <string>monospace</string>
  </test>
  <edit mode="append" name="family">
   <string>Noto Color Emoji</string>
  </edit>
 </match>
 <match target="pattern">
  <test name="family">
   <string>serif</string>
  </test>
  <edit mode="append" name="family">
   <string>Noto Color Emoji</string>
  </edit>
 </match>
 <match target="pattern">
  <test name="family">
   <string>sans-serif</string>
  </test>
  <edit mode="append" name="family">
   <string>Noto Color Emoji</string>
  </edit>
 </match>
</fontconfig>

Then, colored emojis will be shown by Qt apps, QTerminal included.

How to disable a shortcut completely?

How to launch an instance to execute a command and keep its window open?

How to add a custom color scheme as user?

Create the directory ~/.local/share/qterminal/color-schemes/ and put your custom color scheme inside it. See https://github.com/lxqt/qtermwidget/tree/master/lib/color-schemes for examples of existing color schemes.

Once you have defined your color scheme, you can select it in QTerminal under File → Preferences → Appearance → Color scheme.

Also, make sure that the name of your color scheme is different from those of QTerminal's schemes, because the latter will take priority.

NOTE: The directory ~/.config/qterminal.org/color-schemes/ is deprecated and should not be used.
