The video card is an ATI Mobility Radeon 9700, however linux recognises
it as a 9600. This hasn't caused me any grief though. I chose the
1680x1050 (16:9) option. glxgears gives me over 2500 FPS (at its
original size) and about 140 FPS when I maximuse it.
The new ati-drivers 8.12.10, or old ati-drivers 3.9.0 www.ati.com (3.11.1 drastically reduces fram rates)
The TFT LCD is your primary display,
and as such the one you'll probably want to get working
perfectly. I had various symptoms with various drivers. In
the end I used the ATI drivers from the ATI Linux download page. Use Slackware's rpm2targz if you don't have an rpm based distribution.
