 |
|
any suggestions?
how to switch it to use the DRI engine?
state:
when I use #startx I'm running great with xorg open-source driver for ati with Direct Rendering: Yes
when I use #startxgl 0 (1,2) never mind on which screen, I have Direct Rendering: no in glxinfo... verbose option don't say anything, everything is running well but 3D is not accelerated => slow
Xorg log says it is on...
glxinfo don't use r200 driver in Xgl
why? i want it... |

Agh!
There is no direct rendering under Xgl at present. That's just how it is.

Maybe this will help to clarify things for you as well?

Thus, as I understand it, the purpose of xgl is to forward opengl commands indirectly to the hardware. And when NVidia actually implements the new extensions in the very, very distant future, then you won't need xgl to play middleman to compiz for the nifty effects. |

Exactly. Don't worry about it though, it shouldn't hurt your performance. In fact, I get better performance in Xgl.

Huh???
Mine is half what it should be with Xgl... And as far as I understand it, there are Mesa patches being added to allow DRI to work... could be wrong though...

Um? When I tried UT2004 in Xgl, I get about 1/10 of a frame per second - normally it's ~60ish. I don't have glxgears handy, but I imagine it'd be similar to honigd's situation.
The solution is fairly simple though: Start another X session to play games in.
There are probably instructions somewhere, but all you need to do is swap to another VC, log in, and run "startx -- :3" or some such, and play the game from in there. I set up a custom session to start a terminal so I didn't have to mess about loading a window manager, but that's a minor tweak.
The up side to this approach is that you can have any other apps running in Xgl (an IM client say) and swap using ctrl-alt-F7/8. It does take a bit more RAM, but I don't think it's that big a deal.

Hmm... that's odd.
I get 5000+ fps in glxgears in normal X and 7000+ in Xgl.
Anyways, a patch was recently added to the mesa ebuild in CoffeeBuzz's overlay and you might want to try that.

Ok, now I know I don't need the line Direct rendering: on no worry about it, i know where it can be redirected to the GF card with mesa, but how can i read it?
The glxinfo says this in X
| Code: | direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
.
.
some more stuff and also extension but now..
.
OpenGL vendor string: Tungsten Graphics, Inc.
OpenGL renderer string: Mesa DRI R200 20050831 AGP 4x x86/MMX/SSE2 TCL
OpenGL version string: 1.3 Mesa 6.5
OpenGL extensions:
|
That's the thing I like... it is something about my GF 
but in Xgl only mesa is presenting itself and no try to use my GF card...
| Code: | direct rendering: No
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.5)
OpenGL extensions:
|
So this is I mean normal isn't it? Btw. I reemerge it every day if something is new in CoffeBuzz's ol ... |

I have realized now, that it can be due to hi usage of processor... Xgl squezes everything, when I have present some window with movement like window with emerging... in fulscreen it mades round 80% CPU usage... so I should wait until some new patches, releases, DRIVERS  will be developed...
Do anybody know how often are proprietary drivers from ATI released?
As is known proprietary drivers make screen distortion with Fire GL R250 = Ati radeon mobility 9000 |

ATI have been good to stick to their goal of one release per month. So somewhere around now next month you will see a new release =)
Hopefully supporting XGL....don't hold your breath though. |

hopefully will support radeon mobility 9000 which is the worst supported card, but better than ati mobility X1600  that's totally unsuported I mean... |
