I have done a bit of googling but still cant find anyone else with this problem.

I have beryl, xgl, working, but slowly, on Intel 945GM (followed instructions on suse and beryl forums)

Get the latest Xgl, compiz and beryl-snapshot packages from here:

http://software.opensuse.org/download/X11:/XGL/

If you still cannot get it working as expected, check the shared memory allocated to video, increase it.

If it still doesn't work, try xgl package from here, it seems to have helped some:

Thanks, but from http://en.opensuse.org/Xgl I read: Direct rendering is active if running glxinfo|grep direct on top of Xorg (not Xgl!) shows you "Yes". On top of Xgl this will always show you "No". Unfortunately, for Xorg having direct rendering is a synonym for having accelerated graphics, and it is more difficult to detect whether hardware accleration is available than it is to detect direct rendering. So my current performance seem to be the best - well - didn't buy the Dell for its graphics speed. My home PC, nvidia 6600, rocks with aiglx enabled.

Never ever compare low-end intel i945 with mid-to-high-end nvidia 6600. The hardware is *much* more capable, and the drivers are much better (they have a *much* larger development team, and access to hardware guys).

nvidia also flies on Xgl.

Yes, but does Xgl allow other GL apps (who needs direct rendering, ie GoogleEarth) to run smoothly? E-Mail disclaimer: http://www.sunspace.co.za/emaildisclaimer.htm -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

In GoogleEarth most menus are black until I move the mouse over. But everything works smoothly. It is not much of a problem.

Xgl only do the window and window framebuffer stuff. all direct rendering is passed directly to the OpenGL driver(aka the Nvidia,Ati,Mesa etc driver). Fullscreen openGL apps like Doom3 are not affected.

Ok, but now Im confused - as in my first post: When Xgl is disabled - everything works fine. Xgl enabled all my GL apps and Kwin crawl (beryl and compiz run fine). How can this be if Xgl just passes through the direct rendering? Intel driver or Xgl issue?

Right, I forgot something. Xgl needs pbuffers for GL applications to still work in a composited desktop. Unfortunately, the open source drivers do not yet support this extension (needs a memory manager rewrite). This is close to being done now.

...

Intel driver or Xgl issue?

Actually, a DRI issue. You may call it driver issue ;)

Even if you move the windows to a different location after startup? Even when rotating the cube then?

AIGLX cannot display GLX content correctly while moving a window. Just checked this on FOSDEM, it's still the same. It also doesn't seem to be able to do projection, so the windows won't be placed correctly / distorted when rotating the cube while an opengl program is running.

You are NOT using AIGLX in the NVIDIA driver - NVIDIA doesn't use AIGLX.

NVIDIA had accelerated indirect rendering (guess what AIGLX stands for) almost since day one (say: 5 years ago or more). The AIGLX framework is *only* used by open source drivers as we speak.

NVIDIA has implemented EXT_pixmap_from_texture as well, which enables compiz - just like the AIGLX and Xgl do as well.

The NVIDIA implementation obviously works very well together with OpenGL and XVideo - though there are still some rough edges.

Can everybody please stop distributing this FUD any further? Wrong statements don't get right by repeating them over and over...

I agree. Part of the reason is that people are just spewing names of components without knowing where they fit in the grand scheme of things. What I would like to see is a list of which groups of these things work best together. Something like, "Given that you use the nvidia driver, these are the best components to use: ...". Or "Given that you are using the XOrg driver, these are the best components to use: ...". I know this is a moving target, but at least this could get many people started with a decent setup. Exploration can happen later. I think that the many descriptions of how to set this up do not make the matter more clear. There is too much of an assumption that everyone knows what the various components are. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Kapellgränd 7 P.O.

Does this mean that the page http://en.opensuse.org/Beryl is also incorrect in saying: Beryl with nVidia drivers - no Xgl/AIGLX "...This uses nVidia's AIGLX; not Xorg's inbuilt/optional AIGLX..."

Well - partially. It just shouldn't be called AIGLX (this sentence is explicitly stating that is not the same as AIGLX as Xorg calls it).

Correcting it. Reads now:

Since Xorg 7.x, composite effects can be used without Xgl and simply an nVidia card. This uses nVidia's implementation of EXT_pixmap_from_texture, not the one from Xorg's inbuilt/optional AIGLX or from Xgl.

...

No, unfortunately. Creating such a page would surely be appreciated.

It depends on whether you want to run compiz on AIGLX or Xgl. Both have advantages and disadvantages. compiz used to only work on Xgl. The current (read: really new) compiz package on openSUSE runs on both, even with ATI's fglrx driver using Xgl. Beryl runs on both, but AFAIK not at all with the fglrx driver, and probably not on NVIDIA with Xgl.

Matthias

But me with nVidia card, Beryl and "AIGLX" (or whatever) - do I place the AIGLX option in the conf file or not? Seeing that its doesn't really use AIGLX?

The question is rather: Is AIGLX finally capable of showing GLX applications correctly? Last time I tried it didn't. Xgl supported GLX from very early on. By principle, Xgl doesn't support direct rendering (this is a major undertaking), but most people won't realize, that they are using indirect accelerated rendering. Q3 e.g. works fine with that.

Before I run "gnome-xgl-switch", glxinfo indicates direct rendering: Yes, X nice and fast

After "gnome-xgl-switch --enable-xgl" and X restart I get direct rendering: No, and X is really slow, unusable (before even starting beryl)

- Direct rendering: No is a FAQ: read http://en.opensuse.org/Xgl#Frequently_Asked_Questions_.28FAQ.29 - Using Xgl *without* a composition manager is typically pretty slow. - Beryl is unsupported from our side. So before doing any bug reports (if issues remain) please test with compiz first.

Beryl performance is ok, not great, but I guess that's because of rending being off.

No.

There is a patched Xgl version since yesterday, which accelerates intel and radeon drivers. You might want to test it:
