ATI Graphics Card UMA?

[Andy Choens]

To anyone who is an expert on ATI Cards,

I've gotten one step closer to getting my ATI graphics card working.

I installed the proprietary drivers and ran the ati's configuration. When I
rebooted, the XServer would start, but freeze up. I learned on the internet
that I could have ssh'd into the box to reset it...I just did a hard reboot.
After surfing on the net I discovered that the driver was interacting with
the card wrong, and that I needed to tell it to use my main memory (UMA)
instead of the onboard memory.

I am now happily running gnome with the proprietary driver. But, it's using
32 MB of my main memory and NONE of the 128 it has sitting on the card.

I would like to know if anyone has any good ideas about something can tweak
in my xorg.conf so I can use the on-board memory.

Below I have attached a copy of my xorg.conf file. I am running a HP zv6000
amd-64 with an ATI 200M graphics card.

Thanks
