Bug Description

Binary package hint: xserver-xorg-video-intel

Running any panda3d sample causes a segmentation fault.

This is the output:

DirectStart: Starting the game.
Known pipe types:
  glxGraphicsPipe
(all display modules loaded.)
get fences failed: -1
param: 6, val: 0
Segmentation fault

The "get fences failed" message get thrown every time an opengl app is started (like glxgears).

On the panda3d forums a poster suspects that it has to do with the intel drivers:

Thank you for taking the time to report this bug. For Xorg related bugs, there is some information we always need:
- /var/log/Xorg.0.log
- the output of `lspci -vvnn`

Moreover, since this is a crash (segmentation fault), we would need a backtrace to find out why it crashes. You may take a look at
https://wiki.ubuntu.com/Apport#How%20to%20enable%20apport for how to enable apport and get a backtrace. You may also do it without apport, look at https://wiki.ubuntu.com/Backtrace .

It seems the apport backtrace didn't work very well in this case. There is almost no useful information at bug 384203. Are you MojoX in that forum thread? There is a useful backtrace there, but it could have more information. First of all, there are some debug symbols missing (?? in the backtrace). They would probably show up if the right -dbg packages were installed. Look at https://wiki.ubuntu.com/X/Backtracing#Debug%20symbol%20information for packages that may have the necessary debug symbols. Also a full backtrace is better: Instead of `bt` in gdb, write `bt full`.

You may also wish to check if this has been fixed in karmic, by using a daily Live-CD from http://cdimage.ubuntu.com/daily-live/ or alpha-2 which will soon be available at http://cdimage.ubuntu.com/releases/9.10/ .

I downloaded karmic alpha-2 netbook remix and have tested the apps. I don't get a segmentation fault and the pands3d apps launch fine.

So it looks like it has been fixed ;-)

Thanks for looking into this.
