ATI Radeon Mobility 7500 in Compaq Evo N610C

Hello,

I got a brand new Compaq Evo N610C. The first time almost everything was
supported out of the box by Linux (RedHat 9). Just one problem is left that
drives me nuts:

My system:
        RedHat 9
        Kernel 2.4.20-19.9
        XFree 4.3.0
        ATI Radeon Mobility 7500
        (more info below)

I want to have a higher resolution on the external VGA output than I have
available on the internal display.

I don't require Xinerama, so my thought was to simple use the Fn+F4 key (for
the monitor selection) to activate the external monitor and then use xrandr
to select a higher resolution.

Well, the Fn+F4 key does not work under Linux at all. Probably because this
is driven by the ATI driver since the external output is the second output
of the dual head capable graphics chipset. However the external output is
enabled by default and shows the same screen as the laptop display. However
xrandr seems to detect that the internal display is not capable of
displaying more than 1024x768 and does not allow me to switch to a higher
resolution, even while the XF86Config (see non-xinerama XF86Config file
below) provides a mode for 1280x1024.

OK, my other approach was to try Xinerama (see the next XF86Config file
below). However this worked very odd. See this screenshot:
http://www.yeap.de/pub/radeon7500xinerama.png. On both monitors I just can
see the right part of the xinerama screen. However the mouse behaves as if
Xinerama is fully working, i.e. the mouse pointer is only visible on one
screen and can be moved from one to the other. When moving a Window over
the border, I get this pixel trash you can see in the screenshot. I have
found some pages on which I can read that some people have a notebook (no
Compaq Evo N610c though) with ATI Radeon Mobility 7500 chipset with a fully
working Xinerama desktop.

Does anybody have a clue, how I can make the external output to display
higher resolutions? I don't mind about Xinerama. All I want is to show a
big desktop on my external monitor.

Best regards,
Carsten
