Updated and Optimized Ubuntu Free Graphics Drivers

**oibaf** · 05-16-2011, 02:47 AM

Some status updated for the previous week:

Mesa

ARB_shader_texture_lod extension, anisotropic filtering and memory optimizations on r600g, bug fixes on r300g.
I also added the patch to fix bug #35268.

X drivers

xf86-video-intel: support for Ivybridge chipset and fixes.

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.

But just to be sure, is there an easy way to install mesa from your PPA while keeping the stock X-stuff from Natty? I've been struggling with Synaptic for some time and I can't get it to work without getting a message about "broken packages".

Enable the PPA and do a:

Code:

sudo apt-get install package1 package2 ...

where package1 ... are the packages you get with:

Code:

$ dpkg -l | grep mesa

Note that it will also install newer libdrm (required by mesa git) and libtxc-dxtn0 (Reccomended by mesa from my PPA).

Then you may want to disable the PPA to avoid to automatically upgrading also x drivers on successive upgrades (and eventually enable it again, upgrade mesa and disable it again when you want a newer mesa git).

Thanks, that worked smoothly. It doesn't seem to have updated libdrm though:

But everything seems to be working fine:

Code:

Also, I found out that it is compiz that hangs/freezes. Killing compiz solves the issue; it restarts and everything works fine again. I expect it to happen sooner or later now that I'm using mesa git. I plan to try this out when it happens again. Please let me know if there's anything I could do besides that to help uncover the problem.

Do you have any idea what is going on with your r600g driver on my RadeonHD 5670?

Trine simply crashes and Sauerbraten does too, it spits out a whole bunch of lines about "EXCEEDED NATIVE LIMITS" and then finishes with Cannot locate shader definitions.

So the freeze just happened. I got a backtrace:

Should I just report it as a bug in r600g or what? I presume it's mesa's fault and not compiz'?

Full gdb output.

Should I just report it as a bug in r600g or what? I presume it's mesa's fault and not compiz'?

Yes, you should open a bug against mesa. Then developers can take a look at it and suggest something.

Trine simply crashes and Sauerbraten does too, it spits out a whole bunch of lines about "EXCEEDED NATIVE LIMITS" and then finishes with Cannot locate shader definitions.

My packages just provides snapshots of mesa from git, also I don't have a card using the r600g driver. Try opening a bug against mesa: https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa so that r600g developers can take a look at this bug.

OK, I updated the dependencies. On the next update libdrm 2.6.25 should be installed.

In the current mesa packages I merge the pipe-video branch to provide VDPAU and XvMC video acceleration drivers. Currently supported:

VDPAU: r600
XvMC: r600 and nouveau

VA API r600 driver can also be built, but it is disabled since it's not supported by developers.

To test it enable this PPA and update all the packages included (see the first post of this thread for more details), then also install the libg3dvl-mesa package:

Code:

sudo apt-get install libg3dvl-mesa

To test the r600 VDPAU driver with mplayer use:

Code:

VDPAU_DRIVER=r600 mplayer -vo vdpau yourvideofile

To test the XvMC r600/nouveau drivers edit the file /etc/X11/XvMCConfig and insert:

Code:

/usr/lib/dri/libXvMCr600.so

or:

Code:

/usr/lib/dri/libXvMCnouveau.so

and restart the X server. Then to test it with mplayer:

Code:

mplayer -vo xvmc yourvideofile

If you get any crashes you can install the debug symbols with:

Code:

sudo apt-get install libg3dvl-mesa-dbg

Note1: thanks to Christian König and Bryan Cain for the feedback about this.
Note2: I moved the nouveau dri gallium driver from the experimental to the standard package and it is installed by default now.
Note3: I don't own a r600 or nouveau compatible card so I couldn't test it (especially the XvMC drivers). If it doesn't work let me know and I'll try to fix the package. I can't reply before monday anyway.
Note4: I'd like to add these instructions to the first post but Phoronix disabled editing posts some time ago
