Red Hat Bugzilla – Bug 200679
starting metacity with composite enabled locks up the system
Last modified: 2014-06-18 05:08:25 EDT
Description of problem:
When starting metacity with composite enabled the system locks up after the
gnome splash screen shatters.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Enable composite with gconf-editor
2. Reboot system and log in again
After the splash screen shatters the system lock up. Keyboard is completely
dead, only the mouse pointer can be moved. System has to be shutdown holding the
power buttong > 3 secs.
When composite is enabled after logging in all the gl effects just work fine.
What happens, if you launch "gconf-editor" from the "GNOME" session
and checkmark the "composite" option? In principle, "metacity" should
switch to composite mode immediately which is obviously visible then.
No need to reboot your system, not even to log out.
That works as advertised (as I mentioned in my bugreport @ Additional info).
opened windows from pup stay minimized. Alt-tab wont select them.
To find out if this was composite related I tried to disable the composite
checkbox again, it froze the machine instantly.
After a hard boot the machine completely froze again while starting X. Reason:
composite was still enabled. I had to boot in level 3 and hand edit %gconf.xml
to fix it.
Closing bugs related to the metacity compositor, since we no longer develop it.
