 Posted: Sat Apr 22, 2006 10:27 am Post subject: Compiz makes Xgl segmentation fault |
 |
|
When executing compiz, Xgl produces a segmentation fault and compiz says: X connection to :1.0 broken (explicit kill or server shutdown)
I've tried with glxgears and it occurs the same, but there's no problem with xterm and other non-opengl apps.
Logs doesn't show anything interesting.
I'm using ati-drivers-8.23.7 on an ati mobility radeon 9700, I don't understand very well why is this happening because kororaa's livecd works fine.
Is someone having the same problem? |

Hi,
Some more information would be helpful in figuring this out.
First, could you post your "emerge --info"?
While I assume you're running coffeebuzz's overlay, there are actually three different versions of compiz there -- the original (deprecated) version, compiz-vanilla and compiz-quinnstorm. So the revision of the overlay and the version of compiz you are running would be helpful.
Did you follow the steps in the XGL Howto in setting this up? Did you use the install.sh script to install it? Which method are you using to run it -- in a window under another X server, with startxgl from a command line, as part of a Gnome session? |

I'm running coffebuzz's overlay (revision 165, the last one), I've tried vanilla and quinnstorm, but now the version installed is vanilla(0.0.9_p20060416)
I have followed the steps in the howto, tried to install with the provided script install.sh and also by hand. The method I use to run it is in a window another X server with startxgl and by hand.
The problem must be in something related to glx, because I can't even execute glxinfo from a xterm inside Xgl.
Hope this will help, and thanks  |

This is what I get from stracing XGL command:
| Code: |
ioctl(0, FIONREAD, [0]) = 0
select(256, [0 4 5 7], NULL, NULL, {586, 173000}) = 1 (in [7], left {586, 173000})
ioctl(0, FIONREAD, [0]) = 0
gettimeofday({1145754639, 806468}, NULL) = 0
read(7, "\223\24^\0\1\0\0\0\2\0\0\0e\1\0\0GL_ARB_imaging G"..., 4096) = 412
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

And this is from compiz:

| It really does look like GLX, and since you seem to be running ATI (video_cards_fglrx) perhaps a change in driver version would help? Are you running the latest masked version, 8.24.8? |

I've tried without opengl USE flag and with ati-drivers-8.24.8 but the same result 
¿Maybe it's a problem with xorg and/or mesa? I've already recompiled it a few times  |

More information... when I recompile ati-drivers, the output says:
| Code: |
QA Notice: the following files contain runtime text relocations
Text relocations force the dynamic linker to perform extra
work at startup, waste system resources, and may pose a security
risk. On some architectures, the code may not even function
properly, if at all.
For more information, see http://hardened.gentoo.org/pic-fix-guide.xml
Please include this file in your report:

QA Notice: the following files contain executable stacks
Files with executable stacks will not work properly (or at all!)
on some architectures/operating systems. A bug should be filed
at http://bugs.gentoo.org/ to make sure the file is fixed.

I don't understand very well this, ¿someone knows anything about it? I'll read the guide on how to fix it... |

Mxyzptlk, you can ignore those qa messages.
Better read the xgl thread and if you still have not found the solution ask there and not in a new thread.
