If you are working on a high resolution screen and have a hard time reading the text, this one is for you. With a few manual adjustments, most if not all applications happily scale to 1.5x to 2x - likely others, if you go trough some trial and error.
- Menu > Preferences > Advanced Settings > Session Settings
- Look for “Environment (Advanced)” on the sidebar
The following values work well for me (2560x1440 on a 14" screen) but depending on your eyes, screen size and resolution, you might want to adjust.
GDK_DPI_SCALE = 1.5 GDK_SCALE = 1.5 QT_AUTO_SCREEN_SCALE_FACTOR = 0 QT_SCALE_FACTOR = 1.5 XCURSOR_SIZE = 26
To apply, simply log-out and back in. Better yet, reboot.
