I've wrestling with this for a while. AFAIK you need the mach64 kernel
module loaded before you can activate/load the ati driver and DRI for
full 3D acceleration.

You will never get "full" acceleration(what card/driver does?). But
it'll be noticeably faster than having "no" acceleration.

Maybe "full" was tooo strong...I'll settle for "some" ;-)

I don't know how up to date it is, but it helped me way back when I had
an ATI Mach64 laptop.

A useful but antique reference I also found a while back. Supposedly the
code was rolled into X.org recently but they disabled DRI in the newer
code release for some sort of security issue which some sites (such as
DRI) claim to be resolved in 2007. But, for some odd reason I can't find
the mach64 kernel module even though its enabled in the latest kernel.

Don't forget this in your xorg.conf (or XF86Config(-4)):

Section "DRI"
Group "video"
Mode 0660
EndSection

So that "root" AND "users in the video group" have access to
acceleration. 0666 if you want everyone to have access. Not quite sure
why my current semi-up to date xorg and fglrx driver required me to make
that 0666 adjustment myself. 0660 has worked for me for years, "until
now".


well, fglrx can be a bit cranky...


At least I'm back in 1280x800 mode. After manually moving/deleting
various remnants from other versions. Fortunately the date/time stamp
put those in 2006 where all of the new ones were Dec 2007. Even some /
etc/fglr* and friends laying about screwing with things. Debian might
be easier to maintain in the long run, but ATI is NOT. Mom's birthday
is coming up and I'm looking at an nVidia 8800 GT. Fewest headaches so
far, even if I do have to start X with "startx -- -ignoreABI".

Actually, you shouldn't need -ignoreABI with the newer nvidia drivers and
Xorg 7, at least since driver version 76.x or 77.x (can't remember which).
