Re: [gentoo-user] 3D Acceleration With Laptop - Radeon Xpress 1100 IGP

[Alex Schuster]

Hi Drew!

I think I had a similar problem with my ATI card. I did not solve the 
problem, because I am using another (nvidia) card now. But I'll forward you 
what someone replied to me, maybe this will help you. BTW, the unmerging 
and re-merging of genotoo-sources described below is not necessary.

Good luck,

	Alex

I can help you wirh your 3d accelaration problem. the thing is that ati
stopped the support for the older cards since driver release 8.28.8. So
what you have to dois

emerge -C ati-drivers ati-driver-extras gentoo-sources

(Sorry if I explain too much in detail but I do not know how familiar
you are with gentoo)

echo '>x11-drivers/ati-drivers-8.28.8-r1' >> /etc/portage/packages.mask
echo '>x11-drivers/ati-drivers-extras-8.28.8' >> /etc/portage/packages.mask


Now it depends on which kernel you use. I tested it in 2.6.19 and
2.6.20. If you are going to use the 2.6.20 kernel you has to modify the
ebuild in line 162. Change

epatch "${FILESDIR}/ati-drivers-2.6.19.patch"

to

epatch "${FILESDIR}/ati-drivers-2.6.20.patch".

Recreate the digests

ebuild /usr/portage/x11-drivers/ati-drivers/ati-drivers-8.28.8-r1.ebuild
digest.

Thats the first thing. Second is a problem with the version of the
driver. The x11 they support is 7.1, and for xorg-server it is 1.1.1-r5.
So probably you have to downgrade your X

echo '>x11-base/xorg-x11-7.1' >> /etc/portage/packages.mask
echo '>x11-drivers/ati-drivers-8.28.8-r1' >> /etc/portage/packages.mask

then the big emerge could start (Make sure fglrx is your video card in
make.conf)

emerge gentoo-sources
emerge xorg-x11
emerge ati-drivers ati-drivers-extra

then

eselct opengl set ati

This speeds things up for me from up 200 to 2000 fps.

In short this is the guide. If you need more detailed help ask.
