Doesn't work: Xgl, Compiz, Dapper

So, I know it's all brand new technology that isn't even really supposed to be used yet, but being the power user I am, I just had to jump on top of Xgl/Compiz. For the uninitiated:

http://en.wikipedia.org/wiki/Xgl
http://en.wikipedia.org/wiki/Compiz
http://www.freedesktop.org/~davidr/xgl-demo1.xvid.avi

I figured having my entire X server rendered through OpenGL would cause problems, but honestly it hasn't been all that bad. (Well, the WHOLE X server isn't rendered yet, but it's close enough.) Unreal Tournament 2004 runs... not well, but it runs (that'll be fixed in future releases). SecondLife doesn't run at all.

Here's the output:

Now, I can pretty easily switch the new hotness off and everything runs fine. Basically, if Xgl isn't running (even though I technically have X11R7 installed), there's no problem, but if Xgl is running, SecondLife will not.

So I know it's not exactly pressing because this technology isn't going to be available in any serious capacity for a few more months, but it is a fairly straightforward install under Ubuntu Dapper (which obviously I am running and keep fairly up to date.)

Thanks for the support, LL! And thanks in advance for future development!

I do have a feeling that if this is a genuine app-level (rather than X implementation) bug and it's fixable, then it's an SDL-level bug, since it's SDL that wraps most of the GLX-related stuff.

Report it to David Reveman, I think this is Xgls GLX code being incomplete.

I feel emailing him directly seems kind of rude... is there some kind of Xgl bug tracker? I wasn't able to find one upon quick google search other than the big FreeDesktop bugzilla.

I don't think it's rude, people email me privately with bugs all the time

That said Xgl discussion takes place on the xorg list, you can reach him there.

Drooool

When you rin XGLX, applications no longer see your real X server, so, as far as my experiments have shown, you get a subset of your graphic card capabilities, only those that are offered by xglx.
I think in the future they ought to detect the capabilities, wrap whatever does need to be wrapped and just "tunnel" the rest.

I'm running into the same exact issue here. I got it to run but it its extremmely slow.

Since SL uses quicktime for video, and quicktime doesn't work in Linux, is SL going to imploy something different in the future to replace quicktime?

I'm curious how you were able to get it to run. I'm using the "newer" Xgl apt source:

deb http://metascape.afraid.org:13666/apt dapper main

which has very bleeding-edge stuff, quite the bit more up-to-date than Ubuntu keeps it officially. I'm actually able to get to the login screen now, and it seems to log me in, but then as soon as it tries to render anything, bam, crash, with new info:

2006-03-30T18:58:25Z INFO: Stopping GL during changeDisplaySettings

It looks like it a feature missing in just the Nvidia driver. I'm running a ATI FireGL and a ATI Radeon 9600 All In Wonder (for the 4 heads + video capture).

I'm running Xgl + compiz + Ubuntu Dapper + Second Life and get roughly the same performance as turning it off, although I have most all of the eyecandy turned down or off. Only problem is with this setup my machine hard locked a few times, whereas running Xgl + compiz otherwise is rock solid on my system. Turning them off and booting in to a normal X server I can run SL without lockups, in fact I ran four clients side by side just fine. In Windows running just one client plus any other app causes the swap file to grind the hard drive to a pulp.
