Dual Screen with ATI Radeon 2400


Hi folks!
I am having troubles getting into dual screen mode with an ati radeon
2400. I'd like to get an "expended" mode.
I am just seeing the same on both screens yet. Unfortunately the
right screen (vga) has a lower resolution than the left one (dvi), and
both screens show me the lower resolution, if they are both plugged in.
If I unplug the right screen. I get the high resolution on the left
monitor.
Have a look at my Xorg.conf, perhaps you can help me. Here's also `lspci
