XGL

[ianegg]

I just replied to this same suggestion in the other thread... I really think it was a bad idea to start a second thread.

Will it work if I emerge gnome-base/control-center --nodeps ? I'll try shortly, anway.

Computer says, "no."

[pijalu]

Pijalu, are you going to update it? I have problems with compiz using your overlay...

Last update: http://users.skynet.be/muaddib/my-xglov ... 10.tar.bz2

after installing the overlay:

Code: Select all

emerge mesa xgl compiz glxcompmgr

Btw... don't do that if you have a working xgl...
(this is the last update i do... tired to grap src from cvs, compile, tar cvs, update ebuild and reupload )
EDIT: this overlay version should include a working glxcompmgr... dunno the use but who knows....

[fuoco]

what's the difference between hanno's and pijalu's overlays ? I don't know which one to use...

Just wanted to thank you pijalu. Got Xgl and compiz working great with your overlay. Never thought that my 9500pro would make it to such a great linux desktop experience (I just can't stop playing around with my "wobble-windows"!).
Let's hope that the whole thing will soon be ready to be used on a productive system...

greets

PS: The only caveat I experience is that my beloved Konqueror is not working at all with gnome-window-decorator. I hope for Zack Rusin to finish the KDE stuff soon for I could not manage to compile what is in CVS yet.

With Hanno's latest overlay (200602101), Xgl fails during configure, saying that it can't find depthstencil.c inside the Mesa tree. I checked this out, and symlink-mesa.sh is what wants it and can't find it (quite rightly, it isn't there). Unfortunately it seems that Xgl's makefile will be using it as a dependency in build, so this is something that is rather inconvenient and makes me wonder how anybody else managed to get anything to compile

I'm now having a go with Pijalu's overlay to see if that behaves any better - I notice that it's using a different Mesa, for starters.

[ianegg]

what's the difference between hanno's and pijalu's overlays ? I don't know which one to use...

Hanno's ebuild use the lastest CVS source, whereas pijalu took a snapshot of the various sources he knew to be working.

[fuoco]

But I think hanno uses a release of Mesa and not cvs, and that is why xgl now fails to compile - some changes in cvs of xgl require changes made to mesa cvs.

[smcallis182]

So I got it installed, but it, of course, doesn't work since I'm running the nvidia driver's.
I get the can't find GLX_EXT.... stuff and stuff about not being able to find pixmap data.
I emerge kompose (which uses composite if it's available), and that gives me the same pixmap error.
Has anyone figured out a fix for the nvidia problems?
Is pretty much everyone that has gotten it running using ATI hardware? (I've got an FX5200 for the record)

[ianegg]

Ah, you're correct fuoco. I was using pijalu's overlay for mesa and just assumed Hanno had left it on CVS.

smcallis182, did you remember to put LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ in front of compiz? (ie. LD_LIBRARY_PATH=/usr/lib/opengl/xorg-x11/lib/ compiz --replace gconf &)

I have a 6800 and it works fine for me, though I did have the black window bug for quite a while.

Yeah I sure did, I tried everything really. I tried just loading up xgl and running glxcompmgr and that just kind of freezes and turns things black till I ctrl-c the process, haven't gotten compiz running at all. What version of the nvidia drivers are you running?

[Senori]

Pijalu, are you going to update it? I have problems with compiz using your overlay...

At least on my system, your overlay eventually ends with errors that libGL.la doesn't exist (and it doesn't).

[Haystack]

At least on my system, your overlay eventually ends with errors that libGL.la doesn't exist (and it doesn't).

"locate libGL.la" will give you a list of existing libGL.la, copy one from the overlay to /usr/lib/. Don't forget to check if the libGL.la you're going to copy has content, if not, look for another.

If compiz is complaining about the missing extention, but glxcompmgr is working (albeit with the black window bug) then it seems you're using an older version of Mesa that's been patched before the name of the extention was changed.

I'm using the 8178(-r3) drivers. Have you tried pijalu's overlay? I haven't tried his final update, but it uses snapshots of the code that work for him.

I used pijalu's overlay (the -r2 ebuild for mesa), and I thought I got all the name's changed. What should the name of the extension be for sure? I'll make sure that mesa's compiled with the right name.

And now I'm missing libGLU.so.1 <.<. Locate turns up nothing.

Using Mesa 6.4.3_alpha20060209-r3 from pijalu's overlay.

edit: fixed this a while ago.

I had the same problem. I emerged gnome-light (I didn't have gnome on my system before). compiz subsequently built gnome-window-decoration. I also enabled the gnome use flag for compiz.

it should be a symlink to /usr/lib/libGLU.so.1.3.060402 or something similar. If that file is missing too, I would try re-emerging mesa...

----------Now for something different:

I re-installed the whole thing (ATI radeon 9200 with KDE running) with the newest overlay from Hanno. But now it doesn't work anymore....

after 1 or 2 seconds the xlg crashes with the following message:

Code: Select all

X Error of failed request:  BadLength (poly request too large or internal Xlib length error)
  Major opcode of failed request:  142 (GLX)
  Minor opcode of failed request:  1 (X_GLXRender)
  Serial number of failed request:  94
  Current serial number in output stream:  95

I believe it's a very little thing I completely overlooked, but I can't find the damned problem (or solution). The message implies GLX is broken or missing but running glxinfo doesn't seem to agree with that:

Anyone out there to help me out?

[Senori]

Anyone out there to help me out?

Interestingly, this is my problem now too. . Perhaps Hanno's latest overlay is broken?

hehe that's weird... So my solution to your problem, ends up in our problem... its almost 6 AM overhere so I'm going to take a nap, but I think tomorrow a solution will rise... coz we both having this, i believe ther'se something uncool about replacing libGL or libGLU.

How did you resolve the missing libGLU.so.1 ? making a symlink or re-emerge mesa?

--edit: --
Take a look at this:
A month ago Hanno had a similar problem posted at the xorg-mailinglist:

http://lists.freedesktop.org/archives/x ... 12101.html

"I get this if it tries to use the Mesa libGL.so with the nVidia
proprietry drivers. Try

$ LD_PRELOAD=/usr/lib/libGL.so Xgl :1 -ac

(or wherever your distro installs libGL.so)"

is the response.

So I checked what's about libGL.so in /usr/lib :

Code: Select all

$ file /usr/lib/libGL.so
  /usr/lib/libGL.so: symbolic link to `//usr/lib/opengl/ati/lib/libGL.so'
$ locate libGL.so
  /usr/lib/opengl/xorg-x11/lib/libGL.so.1.2
  /usr/lib/opengl/xorg-x11/lib/libGL.so
  /usr/lib/opengl/xorg-x11/lib/libGL.so.1
  /usr/lib/opengl/ati/lib/libGL.so.1.2
  /usr/lib/opengl/ati/lib/libGL.so.1
  /usr/lib/opengl/ati/lib/libGL.so
  /usr/lib/libGL.so
  /usr/lib/libGL.so.1
  /usr/lib/libGL.so.1.2

$ file /usr/lib/opengl/ati/lib/libGL.so
  /usr/lib/opengl/ati/lib/libGL.so: symbolic link to `libGL.so.1.2'
$ file /usr/lib/opengl/ati/lib/libGL.so.1.2

$ file /usr/lib/libGL.so.1.2
  /usr/lib/libGL.so.1.2: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped
$ mv /usr/lib/libGL.so /usr/lib/libGL.soBAK
  mv: cannot move `/usr/lib/libGL.so' to `/usr/lib/libGL.soBAK': Permission denied
$ su
  Password:
# mv /usr/lib/libGL.so /usr/lib/libGL.soBAK

# ln -s libGL.so.1.2 libGL.so
# exit
  exit
$ LD_PRELOAD=/usr/lib/libGL.so Xgl :1 -ac -accel glx:pbuffer -accel xv:pbuffer

Now it runs incredible!!!

[maw]

I've got it working! Using Pijau's overlay I can get Xgl started and compiz running. For reference:

amd64
Geforce 6800GS (AGP)
nvidia-kernel-1.0.8178-r3
nvidia-glx-1.0.8178

However, compiz does like to freeze up from time to time, and of course I have the problem with the missing OpenGL extension in the nVidia drivers. If that's fixed though, the incredibly bad speed of drawing in the windows should be fixed, and I can't see anything more than polish required. Lots of polish to be sure, and obviously hardware compatibility needs to be improved, but this is one seriously impressive system.

Now if only I could get the wobbly plugin working. It segfaults on startup, and my experiments with GDB so far lead only to Xgl freezing up.

[tulinius]

got the shit working, but can't move windows when using compiz and hanno's overlay. only other problem is refresh from time to time.

i have an intel i810 card

any ideas?

[Donpasquale]

I still got the problem that xgl starts up just fine but as soon as i try to start compiz it segfaults. here is the output of strace when segfaulting:

I used hanno´s latest overlay and everything just compiled fine for me. Does anyone have an idea on what the problem could be?

Thanks in advance,

I just replied to this same suggestion in the other thread... I really think it was a bad idea to start a second thread.

Will it work if I emerge gnome-base/control-center --nodeps ? I'll try shortly, anway.

The other thread is NVIDIA problems specifig (like black windows)

I will add a notice on it

Ty for the great work you are doing!

But what's the direfference of yours and hannos?
http://dev.gentoo.org/~hanno check it out he is still publishing overlays too.

Give us some info about yours.

[LL0rd]

Hi,

yesterday I installed a new gentoo system with modular xorg and XGL. But I can't get the X server up. Error messages like that appears, when I try to start it.

Code: Select all

Couldn't open RGB_DB '/usr/lib/X11/rgb'
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Warning:          Type "ONE_LEVEL" has 1 levels, but <RALT> has 2 symbols
>                   Ignoring extra symbols
Errors from xkbcomp are not fatal to the X server
Could not init font path element /usr/lib/X11/fonts/local/, removing from list!

Fatal server error:

FreeFontPath: FPE "/usr/share/fonts/misc" refcount is 2, should be 1; fixing.

So does anybody have a working xorg.conf für nvidia GF6600GT?
