Myrlyn -- fonts too small -- readable in Yast software manager

tckosvic · April 5, 2026, 2:17pm

I need to increase fonts in myrlyn as they are too small. I find the font size in Yast software manager running concurrently to be fine.

How do I adjust fonts in myrlyn? I use mate desktop but I only want to change fonts in myrlyn.

thanks, tom kosvic

How about a forum search?

I apologize for not searching the other threads. I mistakenly thought my issue was new. I looked at the older now closed threads related to the myrlyn font size.

I do see in my system that myrlyn (read only) has more legible text to me as it is using system font setup. myrlyn (root) has the very small fonts as it is using root font settings.

I believe that the other related threads say that root font setup needs to be adjusted. But I have several apps that I run as root, e.g., timeshift. backintime, grub customizer where the root font setup is perfectly legible. Also Yast software manager runs as root and that is legible. So I don’t want to alter root font size for them.

There was a thread about adding a config file to myrlyn but I did not see a font setting in it unless that is “scale factor”.

Is this a closed issue?

thanks, tom kosvic

Correction to above:

I do see in my system that myrlyn (read only) has more legible text to me as it is using user/desktop font setup. myrlyn (root) has the very small fonts as it is using root font settings.

As I have posted in other “Myrlyn (run as root) font” threads when folks complain about its font - here’s how I run it:

user@machine :~>  sudo -E myrlyn

Basically, it inherits my environment (dark mode, fonts). If I do a “su -l” then execute “myrlyn” , it will run as root account environment (light mode, fonts).

For me (personally) , it’s way less of a hassle to just do the “sudo …” execution than making changes to config files, etc.

You can now also put environment variables for this into a file ~/.config/openSUSE/myrlyn-sudo.conf which is then executed in myrlyn-sudo, the script that is called from the root myrlyn.desktop file:

          if [ -f $MYRLYN_SUDO_CONF ]; then
              # echo "Reading variables from $MYRLYN_SUDO_CONF"
              source $MYRLYN_SUDO_CONF
          fi
          
          # Environment variables to keep for the 'sudo' call
          ENV_KEEP="DISPLAY WAYLAND_DISPLAY XAUTHORITY \
          XDG_RUNTIME_DIR XDG_CURRENT_DESKTOP \
          QT_QPA_PLATFORMTHEME QT_ENABLE_HIGHDPI_SCALING QT_SCALE_FACTOR \

Depending if you choose to use qt6ct as root to change the Qt theme and fonts and then set QT_QPA_PLATFORMTHEME=qt6ct or if you simply use QT_SCALE_FACTOR (use integer values or multiples of 0.25).
