Gimp 2.10 To fix toolbar icon sizes, update Preferences->Interface->Icon Theme->Custom icon size to huge or other value. If menu fonts are still too small you can update an existing theme by copying it from /usr/share/gimp/2.0/themes into ~/.config/GIMP/2.10/themes/ and changing gtk-font-name and font_name in gtkrc into something bigger like Sans 30. Then select the new theme from Preferences > Interface > Theme. When copying make sure to rename the new directory into something different from the original name (example Dark > DarkHighDPI). You can also try using gimp-hidpi (installation instructions are outdated and refer to version 2.8, in Gimp 2.10 the theme should be installed into ~/.config/GIMP/2.10/themes/)
I've done all the above to no avail, nothing changed. I'm not sure where to go from here.
What I did exactly was:
changed the settings in preferences and made the icon size huge.
mkdir ~/.config/GIMP/2.10/themes/DarkHighDPI
from within
/usr/share/gimp/2.0/themes/Dark
I
sudo cp -r gtkrc ui ~/.config/GIMP/2.10/themes/DarkHighDPI
I edited the gtkrc file with sans 30 for both the gtk-font-name and font_name
Then from within the gimp program again I changed the theme settings to DarkHighDPI
rebooted my laptop started gimp, still no change.
I restored a timeshift backup to revert all changes I had made.
