What version of GTK3 does EXEGNU use? If > 3.16, you might be experiencing: https://bugzilla.gnome.org/show_bug.cgi?id=757142 and some of its progeny, such as: https://bugzilla.mozilla.org/show_bug.cgi?id=1269274 Setting DPI in your TDE Control Center's fonts menu should produce the following on your system: # xrdb --query | grep dpi Xft.dpi 120 Xft.dpi does not apply to all of Xorg and Xorg applications. To enjoy 120 DPI in all of Xorg, 120 must be applied /to/ Xorg. There are various ways to do that. I do it globally in one of two ways: 1-setting DisplaySize in /etc/X11/xorg.conf* 2-xrandr in a global startup script somewhere in /etc/X11/. For those using a proprietary NVidia video driver, there exists an explicit dpi option for the xorg.conf its installation created. An alternate method I do not employ is finding the xinit script that actually starts Xorg and editing the start line to include the desired DPI value. Done correctly, xdpyinfo will also report 120. Also if done correctly, and GTK3 version is 3.16.x or less, the global Xorg DPI setting will make the TDE Control Center DPI setting redundant, thus unnecessary. If GTK3 is >3.16.x, then Xft.dpi will ultimately need to be set to match the desired setting, which can be done in /etc/X11/*Xresources or .Xresources as well as indirectly in TDE Control Center DPI. I don't know why TDE Control Center DPI has only the three choices, but setting Xft.dpi through other means offers choosing any arbitrary value, e.g. 168, 133, 220, etc. Global Xorg DPI is similarly unlimited. -- "The wise are known for their understanding, and pleasant words are persuasive."
