[gentoo-user] xfce and screen resolution

[Michael Sullivan]

A few months ago my wife switched from gnome to xfce because gnome was
just too slow. I performed the X upgrade on her computer last night, and
now she can't get her usual screen resolution of 1024x768 because it's
not on "the list".  Is there a way I can get it on "the list"?  She
doesn't have an /etc/X11/xorg.conf file, as the upgrade guide
recommended getting rid of it.  Several sites on the 'Net suggested
using the xf86Config file, but she doesn't seem to have one.
