Hi friends,

I got a IBM Thinkpad A30P to set up. It has a ATi Radeon Mobility with 8M Video ram. I used Slackware 8.0. Initial X doesn't work with the XFree86 4.1.0 that comes with Slackware 8. Then I downloaded binary tgz's of 4.2.0 and installed it. This time the card is detected and X appeared. But the screen is messed with parallel horizontal "ghost lines". Funny thing is the mouse cursor looks fine. I suspect it's the modeline. Any suggestions what to do? many thanks!

I have the same problem on my Thinkpad A30, and I also tried yesterday
with XFree 4.2.0 ... What I see in the log-file from XFree is, that it
tells me "[agp] AGP not available".
I have no idea what to do. What I read in some postings is, that
the kernel has to load agpgart module (don't ask me why), but if I try
insmod agpgart I get some error like "cannot initialize module" or something
like
this.

What I use now instead of the "radeon" driver in the XFree config file,
is the "vesa" driver. This works.
Also the radeon driver works, if I use the Option NoAccel, but then
you can forget the performance ...

Do you have an idea what to do, that the agpgart module can be used?

I use RedHat 7.2 out of the box, and installed XFree86 4.2.0

add the line

options agpgart agp_try_unsupported=1

to your /etc/modules.conf file, and then do modprobe agpgart.

Hi, I tried that. At first it worked fine. But after I reboot, the messy lines came back again.

ggestions what to do? many thanks!

That probably means that the module is not being automatically loaded at
boot time. You can try adding

modprobe agpgart

to your rc.local file in /etc/rc.d

I solved it. It was due to the kernel compilation ..

See: http://members.surfeu.at/m.koller/IBM-Thinkpad-A30-RedHat7.2.html
