The default font is Sun 9. But this font looks different under the root account. It becomes very small, so I have to change it to Sun 12. However this font looks good under user accounts.
the DPI probably gets set/forced by some script, check its value. Or Xorg fails to read the screensize when run with a non root account. The DPI is not managed by xfce, it relies on the X server.
I solved the problem! The dpi is actucally set by the Xfce. This is a pice of /etc/xdg/xfce4 if test -r $BASEDIR/Xft.xrdb; then cat $BASEDIR/Xft.xrdb >> $XRESOURCES elif test -r $XFCE4HOME/Xft.xrdb; then mkdir -p $BASEDIR cp $XFCE4HOME/Xft.xrdb $BASEDIR/ cat $BASEDIR/Xft.xrdb >> $XRESOURCES else # Those are fallback settings, use the ui plugin to change it # or add your overrides to ~/.Xresources # Xft DPI: 96 # Xft.hintstyle: hintnone/hintslight/hintmedium/hintfull # Xft hinting: 1/0 cat >> $XRESOURCES << EOF Xft.dpi: 96 Xft.hinting: 1 Xft.hintstyle: hintmedium EOF fi But when you change your font settings with the User Interface Manager Xft.xrdb(in ~/.config/xfce4/) is created and without Xft.dpi: 96 ))) so you get very small fonts evrywhere. It will be cool to add a dpi control to the User Interface Manager.
"It will be cool to add a dpi control to the User Interface Manager." It sure would!
there is one in trunk since rev 25770
