I'm not quite sure I understand what you are getting at. which
resolution is not adapted to what? the laptop panel? the beamer? As
far as I can tell, it seems to be doing the right thing. Right now
the driver defaults each output to it's preferred mode (based on edid
from the monitor):
(II) RADEON(0): Output LVDS using initial mode 1440x960
(II) RADEON(0): Output DVI-0 using initial mode 1024x768
what do you want to happen? if you'd rather have then both at one
resolution, you can use xrandr to change the mode on either or both
