Well, it's not exatcly clone mode if the second screen is set up
using "xrandr --output VGA-0 --auto --right-of DVI-0"? :)
First I tried disabling the bogus connector using 'Option
"monitor-DVI-0" "bogus"' and 'Option "Ignore" "true"' in the
corresponding Monitor section, but that didn't work (X would refuse
to start with 'no usable screens').
Right now I'm using 'Option "DefaultConnectorTable" "yes"',
which works for me as far as the connectors are concerned.
However the default resolution of the secondary Monitor is now
1280x1024 instead of 1600x1200. So I still have to run xrandr in my
.xsession to change to native panel resolution even though I'm
saying 'Option "PreferredMode" "1600x1200"' in the xorg.conf:
IMHO randr should use the native resolution for both monitors by
default.
Also, the "ConnectorTable" option seems to be undocumented?
At least it's not mention in the radeon(4) manpage (however it does
mention the "DefaultConnectorTable" option).
