Dell 600m (Radeon R250): External monitor not supported

[Ben Maurer]

On a Dell 600m laptop with a Radeon R250 video card, external monitors do not work in the default dapper install. I was able to fix this with the following additions to my xorg.conf:

Section "Device"
        Identifier "ATI Technologies, Inc. Radeon R250 Lf [Radeon Mobility 9000 M9]"
        Driver "ati"
        BusID "PCI:1:0:0"
        Option "DynamicClocks" "on"
        Option "MergedFB" "on"
        Option "MonitorLayout" "LVDS,CRT"
        Option "CRT2Hsync" "50-75"
        Option "CRT2VRefresh" "50-82"
EndSection

This is something that should probably be auto-detected.

We currently don't have any automated support or GUI tools for configuring secondary monitors. So editing the xorg.conf file as you have done is the recommended approach. This is of course something we need to consider developing, so I'm marking it as a wishlist item. Thanks for reporting.
