These are the steps which work for me:
- system->admin->display->hardware
set to generic LCD of the right size
log out
- system->admin->display->settings
now you should be able to set the max resolution
log out
- system->prefs->hardware->ScreenRes
now you should be able to set what you really want
log out
That works for me, although it feels very "Windows-ish" to keep logging out.
Note: works on FC9 & FC10, similar works on FC11, but that system is in use and
I can't play right now.
