Phoronix: AMD 8.42 Driver Brings Fixes, AIGLX!

Today it's now time where the fglrx driver reaches yet another milestone. Not only does today's release address many of the outstanding bugs for the earlier GPU generations while also introducing a few new features, but it also delivers AIGLX support! Yes, you read that right. You can finally run your ATI graphics card with the fglrx driver and run Compiz, Beryl, or Compiz Fusion without using XGL! This is coming 13 months after NVIDIA had introduced its AIGLX support, but now just days after the release of Ubuntu 7.10 Gutsy Gibbon it's here for ATI hardware. Granted, if you were using an older ATI GPU with the open-source Radeon driver, you could have been benefiting from AIGLX already.

Faster than light... and AMD.com.

anybody any luck with .23? it says the issues are with 64 bit, how about on 32bit?

fixing the compile issues is no problem, but after that it just segfaults

[Game_boy]

Please help! I have two cursors (one embedded on the screen), my xorg.conf is messed up, aticccle has a "segmentation fault", aticonfig crashed X and I don't know what'll happen if I restart.

I used sudo sh <filename> and chose Manual then ticked all the boxes.

What can I do to cleanly reinstall it? I disabled the old version of fglrx that came with Ubuntu in the manager, but I did it between the install and the reinstall.

Should I re-enable it? Reinstall 8.42? Give up?

I have Ubuntu 7.10 x86 and an X1950PRO (R500).

Will this driver allow those of us with two screens to run Compiz across both? Before with my ATI card I had to use xinerama, which compiz didn't support because apparently it only did textures up to 2048x2048. Now I have Gutsy and I read that xrandr is available and should alleviate these concerns, especially with this new driver?

Using the 2.6.23 kernel on X1600 hardware (Macbook Pro), the following patch seems to work for me:

I'm guessing this is all caused by the undefined symbol...

EDIT:

Well, I'm a fool. I have direct rendering working now... compiz still won't start up, but I'm getting closer.

[gummybearx]

i have opensuse 10.3 and 64 bit, and i got it working. SaX2 wont work for me though, it sets up the display, but just flashes the cursor at me.

i had to run "aticonfig --initial --input=/etc/X11/xorg.conf" or w/e. then x (7.3) could start.

but compiz dies when i try to load it, complaining about GL extentions or something. also, chromium bsu freezes EVERYTHING.

[Kano]

Well the test results with Xorg 7.3/Xserver 1.4 are not that positive as the review only uses Xorg 7.2/Xserver 1.3. There you have got no AIGLX support, also there must be a driver init failure, as the first 3d app with Xserver 1.4 never works (you have to stop it!), only the ones after. This did not happen with 8.41.7 - needed -ignoreABI however, so I would call it a regression as older drivers work better with it. That the packageing scripts are only tested with 32 bit I would say is "normal" for ATI For Debian/Ubuntu users I added already the needed patch to my script - for others wait for someone else *g*

[SlickMcRunfast]

It works!

I'm on Ubuntu 7.10 with a Dell Ins 8600 Ati Mobile Rad 9600.

All I used was these two links and magic happened.
