Description of problem:
We got working an ATI Radeon M6 LY w/16mb of video memory (on an A30 ThinkPad),
then switched the hard drive to the same model ThinkPad with 8mb memory and it
So I ran Xconfigurator, and it detected ATI Radeon M6 LY, and I entered 8bm
memory and selected generic laptop panel at 1400x1050. It couldn't start the
server. We tried selecting all the different panels, we tried putting 16mb and
4mb of memory, and it wouldn't work. Finally I looked around and manually added
"VideoRam 8192" to the device section for the ATI card in the XF86Config and it
Version-Release number of selected component (if applicable):
Steps to Reproduce:
I only had two computers to work on, an ATI Radeon M6 LY w/16mb memory and an
I ran XConfigurator on the 16mb one, and it worked.
I ran Xconfigurator on the 8bm one, selecting 1400x1050 laptop panel and 8mb
memory and checking most of the modes (except 1600x1200), and it didn't work.
Actual Results: Xconfigurator flashed a couple of times, then said there was a
problem, and gave me options of back and quit. startx didn't work after that.
Expected Results: When you select 8mb ram, it should automatically add the line
"VideoRam 8192" to the device section for the ATI card, which is what made it
work when I added it manually.

This is the XF86Config file that worked with the 8bm memory, that I edited.
The ATI Radeon Mobility is not supported by XFree86 4.1.0. I added
some patches to XFree86 from ATI so that the hardware _might_ work, but
it's only there as a convenience to our users in hopes that it works
for them. The Radeon Mobility is not officially supported in 7.2.
Full Radeon Mobility support is available in XFree86 4.2.0 however in
rawhide, so you may want to upgrade to the rawhide packages if you have
any problems with 4.1.0.
Hope this helps.
