Force KDM fonts DPI – openSUSE

If the fonts on your login screen are too big, usually due to attaching external monitor, edit /etc/sysconfig/displaymanager, and append -dpi # to DISPLAYMANAGER_KDM_LOCALARGS.

For example:

DISPLAYMANAGER_KDM_LOCALARGS="-dpi 75"

You should restart KDM (rcxdm restart) after doing so.
