Hi, fellow Linux user (PCLinuxOS here: Love it!) First, enable view of hidden files in file browser ie the .xxx files. Then there are 2 ways to sort this: Globally for everything: in which case you can change the global desktop fonts (I use Mate, & font is changed by System Preferences>Appearance>Fonts, then set as desired. Other Desktop managers are handled in a similar way. If you only wish to change font in Gnucash: You can follow the instructions in the Gnucash Wiki: (extract) Via settings.ini Create if necessary and add the following line to GTK_CONFIG_HOME/settings.ini:
[Settings] gtk-font-name=Arial 14 (end) in my case the file was in (HOME)/.config/gtk-3.0/settings.ini nb: I use Midnight Commander to look & edit these types of jobs. I actually used font size 16. Gnucash recently changed to gtk 3.0, & you will need to look for the config file. I found all this info by Googling, so I feel it is important to try a bit of Googling first! It seems the Linux community is a bit behind updating the tools to change screen Scaling particularly with huge high definition displays. It will happen but until then one needs to adapt. Please! Don´t give up! There are people here to help, but also one needs to help themselves (Google is yr friend too). The developers of Gnucash, & Linux developers generally are fantastic! Please do not go back to the dark side (TIC)! On Wed, 7 Jan 2026 10:55:04 -0600 "Jerry Criswell (JC)" <[email protected]> wrote: > Sorry.
