[gentoo-user] XGL + Compiz + OpenGL issues

I think this issue is probably caused a crappy vid carm, but I thought
I'd check with you guys.  I setup XGL + compiz recently.  I have Xorg
7.1 and an intel i915 vid card.  Everything runs fine and looks nice,
but when I run another application requiring OpenGL (such as a game or
even some screensavers) it runs really slow and I have horrific FPS.
Any suggestions on this issue?

Thanks.

i have had a problem with missing visuals is xorg 7.1 with taht card... i
think it's also there is some versions of 7.0, you have to get the right CVS
date to get rid of them it would seem.
sorry for the unhelpfulness but i just thought i would let you know you
aren't the only one.

that is normal. If you use Xgl, direct rendering does not work - and indirect 
rendering is dead slow.

One workaround, start a second X:
xinit -e xterm -- :1&

there you can start any game you want - it won't be slower and you can switch 
between the xgl -desktop and the game.
