Can anyone tell me how to set default preferences for X using xdm. Just now I'd like to set DPMS blanking for login screen od xdm. In user session I've put "xset dpms X Y Z" in Xsession script. But this script executed only after login. Where can I place this xset call, so that it should be executed on xdm startup? Or may be there is some other way to change X preferences? TIA Alex
