Gallium\r300g doesn't enable 3D acceleration unless S-video output detects a TV.

[Agent24]

I just upgraded to Ubuntu 11.04 (Clean install) and while the new Gallium3D\r300g driver is much better than the older one, the 3D acceleration only functions when a TV is detected on the S-Video\TV-out connector.

When a TV is not detected, it falls back to "Software Rasterizer" instead.

I have a Radeon 9600XT Bravo (VIVO Edition)

When it's working I see in glxinfo output:

OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RV350

When it's not, I see:

OpenGL vendor string: Mesa Project
OpenGL renderer string: Software Rasterizer

Any other information that I can provide to help anyone fix this?

It's a really annoying problem.

[Bryce Harrington (bryce)]

Hey tda7000,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

[Agent24 (tda7000)]

No activity because nobody seemed to want to help, or nobody had any idea about how to help.

I have no idea how to fix the problem myself, and in Natty, the problem is still present for me (even with the latest updates)

When I can actually find the time to do an upgrade to Oneric (and deal with various issues that will no doubt arise) I will be sure to write the results here.

[Agent24 (tda7000)]

I installed Oneric on a separate hard drive in this machine and have tested it a few times, so far without any issue.

So far, S-Video is always detected (although that's even when it's not plugged in) and 3D always works.

I'm not going to say that this problem has definitely been fixed in Oneric, but it looks like it might be. If anything changes I will write it here.
