Red Hat Bugzilla – Bug 186279
metacity crashes on enabling transparency
Last modified: 2014-06-18 05:08:09 EDT
Description of problem:
I tested both aiglx (a bit slow) and exa compositions with kwin and everything
Then i wanted to test the new effects with metacity but as soon as I do:
gconftool-2 -s '/apps/metacity/general/compositing_manager' --type bool true
Starting metacity from xterm, when i enable the composition and the wm crashes
there can be read:
composite all adds window (this line is repeated a lot of times)
composite all ends
Avviso del window manager: Log level 6: Unexpected X error:
GLXUnsupportedPrivateRequest serial 1612 error_code 162 request_code 143
Please notice that this happens on both aiglx and exa.
Version-Release number of selected component (if applicable): 2.14.0-1
Steps to Reproduce:
1. Enable exa or aiglx and restart X
2. login in gnome and enable metacity's compositor by gconf2-editor
3. metacity crashes (you can also see metacity restarting and re-crashing for a

I don't know if this can help you. My videocard is a
Sapphire Radeon 9000 Atlantis [RV250]
i cant do the backtrace because gdb locks the screen until i kill it

metacity 2.14.0-1 backtrace
I've managed to get the backtrace from metacity.
I confirm the same behaviour (FC5, same metacity version).
I've added this to xorg.conf:
Option "Composite" "Enable"
This bug seems to be metacity-only related: as i said before kwin works
perfectly; moreover i've rebuilt the xfwm rpm to include composite support and
it works good too.
I've managed to make Metacity work (still buggy) following the instructions
described at http://fedoraproject.org/wiki/RenderingProject/aiglx
I've installed the Xair server, changed the /usr/bin/X link from Xorg to Xair,
added the lines:
Option "RenderAccel" "true"
Option "AccelMethod" "aiglx"
in the Device section and enabled the Composite, RENDER and DAMAGE extensions.
After doing all this, metacity kept on crashing in runlevel 5 but worked when i
launched startx from command line (with wonderful but ugly and unconfigurable
So ive understood that the xserver included in FC5 isnt supposed to make aiglx
work but metacity crashes because there have been included some experimental
effect. Is it possible have plain metacity compositing effects? I mean such as
the ones included in kwin that just do shadows and transparent windows instead
of those ugly floating windows
Metacity crashes even on a GeForce FX5200. So it isn't a hardware related problem.
I can confirm with GB Radeon 9200, does it need "radeon" or "vesa" driver? I
think I tried both
