Try mplayer -vo gl2. It works much better for me. But XV acceleration in Xgl will be highly improved in the near future.

Of course not ;-) I don't understand your question...

NVidia doesn't use DRI, it uses proprietary closed source drivers. But it works great with it.

Hi folks,
first of all, thanks to Mikos for your work on the PKGBUILDs!
I tried to run versionpkg in xgl from your overlay, and the latest latest xgl cvs (20060216) has a bug or something, it fails with

s_span.c:41:25: error: s_arbshader.h: No such file or directory

To fix this, I added a patch from hanno`s latest overlay called xgl-arbshader-symlink-2.diff to the PKGBUILD and after that, the building went fine. So this is just a tip to those of you who want the latest, and to Mikos if you want to make a new overlay. Thanks.

Thanks! I will update my overlay when I have the time...

FoPref · 2006-02-16 19:29:28

If anyone wants prebuilt packages I have mine here:

http://fopref.meinungsverstaerker.de/xgl/

USE AT YOUR OWN RISK

Perhaps someone who have it already working (Mikos?) could try them out too so that I can see if it is a building problem that I have these problems.

Thanks,

Johannes

p.s.: I have a GF 4800 which is better than most FX 5*** cards and also has shader support... but not GL_EXT_FRAMEBUFFER_OBJECTS

lessthanjake · 2006-02-17 00:29:46

Use the -d option on pacman.

And Mikos, thanks for the PKGBUIKDs, they worked perfectly om my system

Xgl doesn't use direct rendering! Xgl use accelerated indirect rendering.

Edit (for clarification):
Xglx (this is what you are using) is another X server (like xephyr or xnest). It uses your real X server for OpenGL rendering. So you will see indirect rendering in Xglx, but what does matter is that your real X server has direct rendering. Xglx is only one of Xgl implementations - there is also Xegl, standalone X server which runs directly on OpenGL + EGL (but it doesn't work now and it will work only with opensource drivers like radeon r200).

Btw. don't confuse it with real "accelerated indirect rendering", it is new thing Red Hat is working on and it is something different. You can find some info about it HERE.

Remember:
Direct rendering doesn't necessarily mean it is hw accelerated (but yes, most of the time, it's true). It just means the GL calls doesn't go through glx (X11 is client-server protocol, all function calls are transferred from the client to the server, in case of OpenGL by means of glx).

And in the same way indirect rendering doesn't necessarily mean that it is not hw accelerated (but yes, most of the time, it isn't). You could also have hardware accelerated indirect rendering, for example to accelerate OpenGL applications running on other computers or to accelerate Composite extension through OpenGL (this is what Red Hat is working on).

kth5 · 2006-02-17 08:27:58

nice background information. i already wondered why glxinfo stated that direct rendering is disabled. actually i was guessing it could be something like that.

I've read the same on nvidia forums... nice the confirm...

But now why i have to reinstall xgl after a nvidia driver installation?

you have to launch xgl using the script by mikos (startxgl).

By now compiz can't be runned outside xgl (I suppose you write compiz in gnome-terminal after startx)

aneas · 2006-02-17 14:42:22

When I run gnome-session, that gnome splash screen starts up, displays the panels but gets stuck for ... 30? seconds (timeout?) ... until I get a working desktop. Is there any gnome log file I could check for errors, or did anyone else notice this?

lessthanjake · 2006-02-17 14:52:42

Same here, but I have only used the gnome 2.13.90 version together with xgl, but at least I can confirm this i a problem here too.

aneas · 2006-02-17 15:05:48

I got this error with both, gnome from extra and gnome 2.13. By desktop I really mean desktop... That colorful thingy with icons on it behind all other windows

Which is your video card? there are some problems with nvidia gforce mx videocards and with some integrated intel chipset (like 810)...

I have the same problem with my igp gforce2 and it seems doesn't have a *real* solution, only wait for a newer release of the nvidia drivers or wait for xgl's fixes, if it is the guilty or maybe the same compiz :S

See in http://gentoo-wiki.com/HOWTO_XGL, for more info...

Well, there is update in wiki. That "black windows bug" seems to have disappared with latest xgl/mesa/glitz/compiz CVS for people with older NVidia cards. So maybe he can try to change pkgver in all of my PKGBUILDs to 20060217 and recompile everything (there shouldn't be needed any new additional patches now - xgl-arbshader-symlink-2.diff was merged in CVS).

aneas · 2006-02-17 16:55:42

I'm bored. Now that we've got this super fantastic brand new display server there really should be a way to design new _client_ applications. Does someone now how to add semi-alpha transparent window masks or draw such windows in opengl? Like those gears/dolpins in the video?

wiremore · 2006-02-17 19:10:26

I tried recompiling with the latest CVS, but im still getting errors.

Anyone have any idea? Thanks

Thanks for posting the binaries it worked for me too, however like they have said on Xgl Homepage, there is an annoying issue with intel 915 drivers (i810) and it flickers a bit when ju;ping from a desktop to another

Well, that red-brownish shadow color is awful ;-) But how did you changed appearance of shadows?

And btw. does anybody know how to have different wallpapers on different cube workspaces? Usually I don't use GNOME, so I don't know if it is possible in GNOME at all. In KDE, it is possible, but if you turn on Compiz virtual cube plugin, KDE see only one real workspace (similar to GNOME pager applet, which also see only one big workspace).

Great! :-) But I don't understand it, there shouldn't be anything new in it compared to latest CVS. Please, if you have time, try to compile latest CVS if it will also works for you (simply change pkgver in my glitz-cvs PKGBUILD to 20060218 and recompile it).

I was bored and played with the gnome-window-decorator src. You'd love that brown if you'd see the pink shadows i had before Shadows in gnome-decorator are not drawn, but blitted from an image. Using different shadows is as easy as implementing another shadow image. I've tried completely blue borders for active windows on that screenshot, too.
