Hello everybody!
A week ago I've bought a Sapphire Radeon 9000 Atlantis that is powered
by ATI Radeon 9000 and I'm getting crazy to make it work properly on Linux!
After trying the fglrx drivers from ATI website for Linux (that didn't work),
I've noticed that XFree86 has problems to make the Radeon driver work
with my AGP chipset (it's a VIA Apollo Pro 133A with chipsets VT82C694X
and VT82C686A) so I tried forcing it to work as AGP 2x instead of 4x...
...and it worked! That's weird 'cause both my motherboard and my videocard
support AGP 4x!
After that I checked the settings in BIOS and they seemed ok but I still can't
run DRI with AGP 4x... I hope I didn't break anything on my new videocard nor
on my motherboard...
Let's have a look at /proc/pci...
Bus 1, device 0, function 1:
Display controller: ATI Technologies Inc Radeon R250 [Radeon (rev 1).
Master Capable. Latency=32. Min Gnt=8.
Prefetchable 32 bit memory at 0xd8000000 [0xdfffffff].
Non-prefetchable 32 bit memory at 0xe5010000 [0xe501ffff].
...R250??? If I look at glxinfo I can see this (I'm running it as AGP 2x):
OpenGL renderer string: Mesa DRI R200 20020827 AGP 2x x86/MMX/SSE TCL
Don't you find it weird?
I know nothing about the AGP problem (but normally agp is handled by a kernel module, agpgart). But I have a 9200 (which is based on a r250 also or something approaching) and it is handled (correctly, glxgears ~ 1570 fps) by the r200 module of the DRI. So I guess this driver can drive sevral chips of the r200 family.
BTW I have a mandrake 9.2 if you want try it out to have a working DRI (but I installed a recent snapshot of dri, it did not work with the ones provided with the mandrake).
Bye
Manu
