I have no probs with revision 55, do you get some error when trying to run XGL?

Have you also changed to the "new" version of libshadow.so you can get from http://www.fairlite.demon.co.uk/intel.html?

From what I understand the drivers from http://www.fairlite.demon.co.uk/intel.html are maybe better, but does not get DRI working with the latest mesa.
But may be it is just me ...

When I run with the lastest stable Mesa I will get about 1200 FPS with Glxgears and no problems with DRI.

When I switch from the stable to cvs Mesa I can't get DRI, without using the old driver instead of the new. If I do this I still get about 1200 FPS from glxgears. But XGL is very slow with wobbly and switcher, and firefox runs extremly slow.

If use the cvs Mesa and the drivers from fairlite, I get DRI without any problems in normal X, and about 700-800 FPS from glxgears. XGL runs better but it fells like its more CPU heavy than before. Plus the pugin for F12 (I've forgotten what its called) is running extremly slow.

Hope this helps.

Hi every body here. I'd like to share again where I moved so far. I have working Xgl server and fully working drm. Wow cube rotates smoothly, does not break and chops. To achive this I used drivers that I posted later means I can use drivers from:

http://dri.freedesktop.org/snapshots/

and also from here:

http://www.fairlite.demon.co.uk/intel.html

with basically same result. But some new bugs appered to me:

- My fonts in xterm are broken and unreadible, also I can not see what I am writting until I change desktop over, snapshot here: http://paraweb.czweb.org/image/xglfonts.png
- As soon as I move any window (not the cube rotation) Xgl crashes with the message: memory violation access in detail like this:

I've managed to get DRI working on a copaq v2000t with a 945gm (i915_drv)

glxgears is reporting 800-900 fps but when I go to start Xgl it returns with "no screens found"....so close, grrr!!!!

Hi,

(first, sorry for my english)

I can install the newest coffee-overlay without any problems. Only I have to do, to get DRI workig, is to use the drivers from:

I'm back trying to get this working again and seem to be hitting the same brick wall as before, everything compiles fine and I have tried all the different tricks I can find, so does anyone know what could be causing this?

Sounds very similar to what is happening to me now zapata and the output also looks very familiar, I have also just tried vanilla-sources 2.6.16-rc6 with no luck

I swear I'll get this working one day =)

Alright I decided to write this guide in an attempt to help people getting Xgl+compiz running on their i915 chips.

First of all I would like to remind you all that the i915 is not exactly known for its performance (if you've tried to play recent games on it you know what I'm talking about), and therefore, don't expect a miracle. Compiz is usable on the i915 but probably not as fast as you'd like. I am currently using compiz in replacement for metacity, but after a few days I'm beginning to get tired of the scrolling slowdowns on large windows.

Second: Xgl acts like a proxy between your programs and the real Xorg server, so don't expect to have direct rendering inside Xgl, and this is not a problem as long as you still have direct rendering outside of Xgl.

Third: Ignore the frame rate reported by glxgears. The reason glxgears reports a much higher frame rate is because when using composite extensions all rendering is performed in the background and is only flushed every once in a while, so running glxgears inside Xgl is the same as running it outside of Xgl with something covering its window.

Fourth: I can only troubleshoot people who install Xgl and compiz the way I describe here and I will only cover the necessary steps to get Xgl+compiz running on your computers. For further instructions, please read the Xgl HowTo.

Fifth: I will assume you already have Xorg 7 installed. If not, please read this tutorial first.

@stable

first, thanks for your advice!

I try to do it your way, but when I start gconf-editor as normal user compiz is not in the menu. Only as root.

do you have an idea?

Thanks Stable. Can you also tell what kernel version you are using? I don't mean linux-2.6.16-rc5 that is used for kernel heders.

The latest releases of coffee's overlay seem to have problems, please avoid coffee's overlay releases 66 to at least 70. I don't know if those problems are in any way related with the reported crashes, but I had rendering problems with the latest Xgl snapshots on my desktop (radeon 9600 pro). Try rolling back to release 65 until these problems go away. To rollback, run:
