XGL (part 2)

bgreen · Posted: Thu Feb 16, 2006 8:24 pm Post subject: nvidia glxinfo

Running XGL with the binary nvidia driver, but the OpenGL/GLX capabilities available to applications is very limited.
I was wondering if others see the same results from glxinfo as I do, namely 'direct rendering: No', 'glx vendor: SGI', and a paltry selection of available visuals.
Shouldn't it be using glx vender NVIDIA?
Here is my glxinfo output:

Hm, still not running really perfect here :/

compiz still segfaults when running as a non-root user. Root can start an xgl session using the startup script chrroessner posted, but no luck as normal user. All scripts on the wiki-page kind of fail. No window decoration or segfault or some other crap, using all the latest stuff.

When I do have the thing running with chrroessner's startup-script, it's not that fluent. Wobbly, transparent, cube all work, but when moving a wobbly window, it freezes for a few seconds when I stop moving it. It's not like my specs are insufficient (AMD64 3200+ S754, GF7800 GT).

I hope the developers will book some more progress the upcoming weeks and months, and make this more usable ^_^ Best of luck to whoever has te ability to contribute. From what I've seen so far, it all looks sweet.

hi !

i've still got the same problem! I've tried "emerge -C xgl" then "rm -rf /usr/portage/distfiles/cvs-src" then emerge xgl again with latest hanno overlay but still no Xgl executable at the end!

I really don't understand, please help me...

At least Xgl is working on my nvidia geforce4 (I had black windows problems), see here for more:

Note to: Gaenya and bgreen, same here, no direct reendering with the nVidia, the same glxinfo output.

First hing I guess is that there is no need to emerge the alpha version of mesa (I am not using it and everything is okay).

Second, if I understood correctly, all the compiz stuff currently is software rendered by mesa, because the proprietary drivers (I only know of nvidia), do not have the neccessary support. As I read somewhere, nvidia is going to implement this and hopefully we do have hardware rendering support in one of the next releases of the driver. Therefor DRI is not available.

That is the reason, why you must specify LD_LIBRARY_PATH="/usr/lib64/opengl/xorg-x11/lib/" as prefix to compiz.

Maybe not everything is 100% correct what I am saying here, but I guess in the main sense it is okay.

Here is my updates start-script:

my compiz and xgl runs fine with all plugins, i've only one question:
when i add Gnome's Workspace Switcher plugin to the panel, i can only
see one Workspace (the one of the cube's actual side..), is it possible to
have all workspaces of the cube in this panel plugin?

thanks, Christian

Hey, so close to getting this baby to work! I can run Xgl, but when I try whacking compiz on, all hell breaks loose. Ok, its not that bad, but I get a segfault:

I've got it working with GeForce2 MX400, and every efect is working perfectly

Before I had black screen but now everything is working (I did eselect opengl nvidia instead of xorg-x11 and re-merged glitz)
