Doesn't solve the problem for me, but this way, I don't have to specify LD_LIBRARY_PATH=/... each time I want to try to start compiz  |

Very strange:
A new FX5200 I bought for my oldest pc even had the same problem.
Black windows!
Only newer cards doesn't have this problem.
Hope their will be any patch.

I'm nearly sure that the problem is with stencil buffers.
For some reason mesa doesn't implement stencil buffers with old nvidia cards :\
In fact, at the start of glxcompmgr/compiz output you will get a message reguarding stencil buffers, and their absence could cause problems.
I hope this will be useful.

I only get that stencil buffers warning when running at 1400x1050(16bpp), not when I run 1024x768(24bpp), but at the lower resolution, same issue as at the high one...

| I managed to get everything compiled (and I even recompiled with pijalu's new overlay), and I can get xgl up and running, but when I try to load glxcompmgr (even with no plugins specified), my desktop just freezes, I can't move windows, gklrellm stops updating, but it's NOT frozen, I can bring it back if I ctrl-c the glxcompmgr process. When I run compiz --replace gconf, I get the GL_EXT not found...... crap. I've tried recompiling and I'm specifying LD_LIBRARY_PATH, and I am out of ideas. Anyone have suggestions? I'm running an nvidia FX5200 for the record. |

(maybe I should read more  ) |
 What in earth does that mean?
Something like this??:
Xgl is a normal openGL program which is hardware accelerated when using the glx implementation provided by nvidia. Compiz is also an openGL program. It currently needs functions that aren't implemented by the nvidia drivers. At the moment Compiz only runs when using a hacked software based openGL implementation called MESA. The hacked MESA does provide the needed functions, but it can't provide hw acceleration as MESA is software based.

I've got xgl/compiz working on ~amd64 +nvidia 
One thing that makes compiz explode is wobbly so I just don't use it atm.
Spinns/flips and all thta cool stuff
I'll make a video in the next day or so. |

After some further investigation, it looks like it wont be possible to run this on a Geforce2 based card (for now). One needs pixel shaders, and afaik those are only available starting from geforce3...
Not completely sure yet though

Sweet, I've got similar hardware and wobbly makes me blow up too. Everything else works perfectly! |

Hi,
I have the problem with the black windows, too. I've been hacking compiz all night but got nowhere. I know pretty much where the problem is, though, I think.
I'll just keep trying.
Cheers,
Drag0n

A little update: Well, haven't got any further yet...
On the mesa mailing list, thread "GLX_EXT_texture_from_pixmap", I learn that as of February 6, nVidia is working on implementing that extension. But I, of course, don't know whether it'll be in the next release or not. Let's hope for it!
Cheers,
Drag0n

Hope they will release their new driver soon.
Xgl should be much faster then when doing an emerge

This GLX_EXT_texture_from_pixmap is kinda wacky.
If I do the LD_LIBRARY_PATH and point it to the CVS Mesa/lib path it will work on and off. Most of the time it will give me that error but if I keep entering the command it eventually starts compiz successfully. O_o |

My Pc works nearly perfect with compiz and Xgl.
I had to modify my kdmrc (it works with gdm too, just search the forum)
And I had to make a script which starts compiz and gnome-window-decorator and put it into .kde/autostart
It's so nice |

A recap of what we know about the black windows problem:
This problem was already raised in the xorg mailing list[1], but with no solution.
To expand a bit on that message, here's the snippet of code that is run by compiz:
From compiz/src/texture.c +218
| Code: | case GLX_TEXTURE_2D_EXT:
texture->target = GL_TEXTURE_2D;
texture->matrix.xx = 1.0f / width;
texture->matrix.yy = -1.0f / height;
texture->matrix.y0 = 1.0f;
break;
case GLX_TEXTURE_RECTANGLE_EXT:
texture->target = GL_TEXTURE_RECTANGLE_ARB;
texture->matrix.xx = 1.0f;
texture->matrix.yy = -1.0f;
texture->matrix.y0 = height;
break;
case GLX_NO_TEXTURE_EXT:
fprintf (stderr, "%s: pixmap 0x%x can't be bound to texture\n", programName, (int) pixmap); |
The error messages showed when compiz is run indicate that GLX_NO_TEXTURE_EXT is returned by queryDrawable (which is just a call to glXQueryDrawable).
I tried to make the code ignore the queryDrawable value and force the code path through either of the cases, but still I got black windows.
From reading issue 4 of the proposed GLX_EXT_texture_from_pixmap extension[2] and noting that GL_ARB_texture_non_power_of_two is not present in glxinfo, but GL_ARB_texture_rectangle is, then I conclude that the second case is the one that applies to my card (Geforce4 MX).
Maybe this code path is less tested and those coordinates are wrong? I tried to read the GL_TEXTURE_RECTANGLE_ARB spec[3] but couldn't understand any of it
So, the problems are:- This happens in old nvidia cards
- glXQueryDrawable returns GLX_NO_TEXTURE_EXT when it shouldn't
- using GL_TEXTURE_RECTANGLE_ARB should work, but doesn't.
Could anybody post some of this info on the nVidia Linux forum thread[4]? I tried to register but I couldn't because of the email restrictions they impose.

Hi maxcow,
I have the same problem with my Geforce4 420 Go, everything else is working and it's very faaast, even the cube, so the only things remaining are the black windows. I hope it gets fixed very soon because I'm so in love with this XGL that I started using them, even if they are all black 
Cheers,
Julius |

do you really need gcc 4.0.2 to get this thing working? I'm getting the following error compiling cairo under 3.4.4
