Most sizes, fonts can be controlled easily - but for FreeBSD /KDE Plasma the menu fonts are too small. Using the “Open Expert Configuration” should allow me to change fonts, but what about the size? Is there any documentation on the use of this menu?
On the same subject (and as this is about menu fonts) can LO be started in “safe mode” to revert to default values?
You can try the qt5ct program:
First, install qt5ct package via “pkg install qt5ct” in terminal as root. Then start “qt5ct” as user in terminal. In the qt5ct program, go above to “Fonts” and choose the font and the font size as you wish. Click “Apply”, “OK”.
Second, add the following line in your “.profile” file, which is in your home directory: “export QT_QPA_PLATFORMTHEME=qt5ct” (no parenthesis). Make a complete logout and log in again. Done. For me it works like charm.
