A bunch of questions :

- there is a version of fglrx available via Ubuntu package configured explicitly for Intrepid; have you tried running that ?

- your x.conf file has a "NoDRI" option for radeonhd, which I'm pretty sure will stop 3D from working. Did you configure this yourself or was it the default conf that came with Intrepid ?

- how old is the version of radeonhd you are running and where did you get it ?

If you were running fglrx before I would try picking up the latest updates and then use the restricted driver manager to go back to fglrx.

Thanks for the reply.

I had the same problem with the FGLRX drivers, so I am now trying the other drivers. I was also under the impression that FGLRX doesn't support X.org 7.4 yet.

From the repositories, I have:
xserver-xorg-video-radeonhd 1.2.1-2build2

I tried adding NoDRI into xorg.conf because I was getting a message in Xorg.0.log saying something like "Option "DRI" is not used" before I added it.
(Edit: BTW, it's a Radeon X1600 512 Megs AGP)

Now I have:

Code:

cat /var/log/Xorg.0.log | grep -i DRI
	X.Org Video Driver: 4.1
	X.Org XInput driver : 2.1
(II) "dri" will be loaded by default.
(II) LoadModule: "dri"
(II) Loading /usr/lib/xorg/modules/extensions//libdri.so
(II) Module dri: vendor="X.Org Foundation"
(II) Loading extension XFree86-DRI
(II) Loading /usr/lib/xorg/modules/drivers//radeonhd_drv.so
	Module class: X.Org Video Driver
	ABI class: X.Org Video Driver, version 4.1
(II) RADEONHD: X driver for the following AMD GPG (ATI) graphics devices:
	ABI class: X.Org Video Driver, version 4.1
(WW) RADEONHD(0): Option "NoDRI" is not used
(II) AIGLX: Screen 0 is not DRI capable
	Module class: X.Org XInput Driver
	ABI class: X.Org XInput driver, version 2.1

As I understand it, a version of fglrx was provided to Ubuntu and published through them a few days ago which supports the other graphics bits in Intrepid. Don't know the details though.

AFAIK the radeonhd driver defaults to building without DRI support, so there is an option you need to specify when building it if you want 3D... and if you build with that option I think it needs headers from drm so drm source needs to be present as well. There is a wiki entry on running radeonhd with dri (linked off the radeonhd wiki page) at : http://www.x.org/wiki/radeonhd%3ADRI

Note the wiki says that DRI and 2D accel are not supported at the same time -- AFAIK this is stopped being the case a month or so ago and the current code should support simultaneous 2D, TexVid and 3D.

3D works perfectly using the default "radeon" (not "radeonhd") driver.

Try changing:

Code:

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"radeonhd"
	Option          "AccelMethod"   "XAA"
	Option	 	"NoDRI"
EndSection

to

Code:

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"radeon"
	Option          "AccelMethod"   "EXA"
EndSection

Not for me it doesn't... When I changed it to radeon, it just gave me a black screen with a blinking cursor. (Well, an underscore, technically)

I know EXA was extremely slow with radeonhd, so maybe that would be the problem? I'll try again later with XAA, but for now I have to work.

**patryk77** · 22 October 2008, 09:50 PM

It works!

Ok, radeon drivers work. I had to uninstall xorg-driver-fglrx for x server to boot though.

3D seems very fast. Now if only it went into 1280x1024.

Thanks for the help guys

Either radeon or radeonhd should have no problem running at 1280x1024 AFAIK. If you want to pastebin (http://www.pastebin.com) your log and conf files someone might be able to help.

I can live with this weird resolution for now... But the problem I have is that Google Earth is EXTREMELY slow.

I tried AccelMethod EXA, XAA and ShadowFB, and it takes a good 30 seconds of black space with stars before the Earth appears, and even then it takes at least a minute or two before it centers and zooms.

I know it's not my hardware, because it ran perfectly with FGLRX.

Billard-GL seems to run even smoother than it did with FGLRX, though it may just be an impression I have... and I know it's not an excellent benchmark tool, but

Code:

$ glxgears 
12775 frames in 5.0 seconds = 2554.842 FPS
13607 frames in 5.0 seconds = 2721.242 FPS
13536 frames in 5.0 seconds = 2707.060 FPS
13578 frames in 5.0 seconds = 2715.494 FPS
13657 frames in 5.0 seconds = 2731.273 FPS

I even tried changing to 16-bit textures, and lowering the quality to no avail. Any suggestions?

Thanks

I forget the details, but search for "disable low impact fallbacks" and that will give some good clues. Best way to set the option seems to be by using driconf.
