Hi,
as first, it's the first time I play with dri, maybe I'm just omitting a
step, but in doubt I report.
I'm trying to use the r300 driver from http://r300.sourceforge.net/ on
aluBook 15" (cpu 7447/7457, radeon mobility 9600). This is what I obtain
following the instruction in r300-driver/README:
http://laera.web.cs.unibo.it/dri/dri.jpg
3 observation:
- the console font is unreadable, but I was getting the same result with
the original xorg dri;
- glxgears render out of the window;
- I get ~700 fps :D (without 100 fps).
Then I've tried the r300_demo(v_0_0_1): I've wrote an ugly fix that just
works for
me for an endianess problem

After executing the demo, glxgears fall down to ~200 fps.
There is some debug info I can post for help?
Thanx, Dario.
