Fw: Graphics support - ATI vs nVidia

[A. Devine]

Hi,

I was wondering if someone could comment on the current state of graphics 
drivers, Im going to upgrade the graphics card in a ZX6000 to the 
fastest/best supported. Does the wonderful sounding open-radeon drivers 
support IA64 with DRI? I gather the closed nVidia drivers work well but 
nVidia has ended their AGP product line last year I believe, so its a bit of 
a dead end.

thanks

nVidia stopped tracking ia64 at least a couple of years ago ... so their
closed driver is only usable on old kernels.

Thanks for that, I now have the ZX-6000 and am using on the supplied Radeon 
7000 (RV100) card with Ubuntu 8.04 (tried Debian too). Ive been trying to 
get DRI working and have been digging through several years worth of mailing 
lists on the various flat out bugs with X on the IA64 platform (which now 
should be fixed I hope!) and other issues. I have got it to the point that 
AGP is working but Im getting a very basic error as seen in glxinfo:

 libGL error: failed to open DRM: Operation not permitted
 libGL error: reverting to (slow) indirect rendering


Usually this is just a permissions issue which is cured by adding:

Section "DRI"
    Mode  0666
EndSection


to Xorg.conf. I have tried that (also tried lowercase) and it just doesnt 
work, makes no difference. Does anyone have any input or even just assurance 
that DRI does indeed work, somewhere and somehow on someones IA64?

Just to update my own email, I upgraded to Ubuntu Intrepid Ibex (Alpha 4 and 
now 5) which includes Xorg 1.5 and new Radeon drivers. It now works "out of 
the box". I had tried Ubuntu 7.04 and 8.04, several Kernel versions and DRM 
changes, this is the first time it worked which would make it appear to be 
some sort of Xorg issue.

Glad to hear that things are now working for you ... but I'm confused
... I didn't think that Ubuntu had an Itanium edition.  A quick browse
of the Intrepid Ibex iso image area (now at Alpha 5) just showed i386
and amd64 iso images.

Its almost like they want it a secret, could do with being a lot easier to 
find alright, but both the latest released version (8.04) and the Alpha in 
test (8.10 Intrepid Ibex) support IA64.

Docs:
https://help.ubuntu.com/8.04/installation-guide/ia64/index.html

"Server" Install CD 8.04:
http://cdimage.ubuntu.com/ports/releases/8.04.1/release/ubuntu-8.04.1-server-ia64.iso
"Server CDs basically means you have to install Gnome/any GUI etc afterwards 
via Apt, no big deal.

To get to 8.10 Alpha 5 I just did a Dist Upgrade in 8.04, the packages are 
being actively built for IA64 even if a CD image hasnt been.
