Updated and Optimized Ubuntu Free Graphics Drivers

[Janell6754]

I've just tested stock Ubuntu mesa with the X drivers from your PPA, and it hasn't produced a crash yet, so it seems it's mesa git that is the cause of this.

[oibaf]

the developer provide another fix. Can you merge it? thank you.

http://cgit.freedesktop.org/mesa/mes...8b3ca4c58076be

It's in the PPA now.

It's in the PPA now.

thank a lot. The bug is fixed.

I wil report to upstream developer

Using this PPA (I just updating the packages less than an hour ago) with kernel 3.3.0-rc5 on amd64, I'm getting a segfault in doom3 (I get the same thing in quake4). Am I doing something really bone-headed here to cause this?

Here's some of my info (I get the same issue with OpenGL2.1 too):

Whoops! Not sure how I missed that, but good catch!

Seems something is broken with libstdc++. I'm using libstdc++:i386, libllvm2.9:i386, and ia32-libs from the standard ubuntu repos (12.04).

I'll look into this issue further in a little while once I have a window of free time.

[hiryu]

Finally had some time to look at this..

There are 2 libstdc++.so.6 files on the system:
/usr/lib/i386-linux-gnu/libstdc++.so.6 (belongs to package libstdc++6:i386)
/usr/lib32/libstdc++.so.6 (belongs to package lib32stdc++6)

By default, applications are looking in /usr/lib32 for libraries, so I tried:

LD_LIBRARY_PATH=/usr/lib/i386-linux-gnu:/usr/lib32 doom3

This fixed the issue and doom3 started right up. For the most part, this system is a standard oneiric box. I didn't muck with any library search paths and what-not. Are the dri drivers supposed to be linked against the library under /usr/lib32 or is something else supposed to be redirecting the drivers to look in /usr/lib/i386-linux-gnu?

[hiryu]

Using this PPA, I'm getting about 41 fps with doom3 on a core 2 quad 3.0 ghz and a sapphire radeon 4870 at 1280x1024. I'll need to check on the other settings later when I get home from work, but I'm using some sort of FSAA and anistropic filtering as well. I must say the driver devs are doing an amazing job. The performance of the open source drivers at this stage is fantastic. I'm not an expert and didn't look for any flaws in particular, but the image quality also seems to be very good as well.

The desktop performance with the open source radeon drivers is also quite good. It provides a smoother experience than my primary desktop which has superior hardware (3.33 ghz i7 980x + nvidia GTX 580). This may be due to the fact I haven't manually changed the power settings for the radeon, and I believe the default is currently to run the card at the highest setting. In about a year when it's time for me to upgrade my video card in my primary box, I think I'll finally be able to get a radeon. As much as I love gaming, I think the 3d performance is already good enough given the lack of games in linux (and in a year from now it should be even better). At this point, my only real concern with buying a radeon is the power management so as to not run up my electric bill.

Thanks for an awesome PPA!

Given how little a 7750 consumes, I doubt you'll notice the few watts difference in a year

[hiryu]

Given how little a 7750 consumes, I doubt you'll notice the few watts difference in a year

But it seems a new driver needs to be created for these cards (with r600g being used as the base). I'm wondering how long this will take to get to the relative maturity of the r600g driver. I wouldn't mind replacing the 4870 in my old box *now* (which is now the family computer). Being 3 generations ahead, the 7750 is probably faster than the 4870, and it's certainly going to run cooler and use less power.
