$ cat .Xresources
Xft.dpi: 102
This file is automatically read when X is started and
before TDE is
lauched by the user and sets the DPI resolution as requested:
$ xrdb -query -all | grep -i dpi
Xft.dpi: 102
Xft.dpi is the means by which TDE-Control -> Appearance -> Fonts: "Force DPI
for
fonts:" is applied. When this is used, it is stored in
~/.trinity/share/config/kcmfonts as forceFontDPI= under [General]. With TDE
closed, you can put any number you please here and it will stick.
Not app apps are affected by Xft.dpi. Xft.dpi is the "knob" by which Gnome/GTK
font scaling is applied. If you wish non-adherent apps to use your specific DPI, X
itself needs a DPI forced. Various methods can do this:
1-DisplaySize in /etc/X11/xorg.con* can do it.
2-The xsession startup script can do it with a -dpi switch.
3-Xrandr can do it with -dpi option either via startup script, which will affect
the entire session, or after startup, by which it will only affect apps started
after running it. This latter method can be helpful in choosing an optimal value.
