Is 'metacity' running?

Nope.

Try starting it from one of your (misplaced) terminal windows:
'metacity&' and see what happens.

metacity: error while loading shared libraries: libGL.so.1: failed to map
segment from shared object: Permission denied

/usr/lib/libGL.so.1.2 is root:root rwxr-xr-x

No further libGL related stuff in /var/log/messages

selinux-policy-targeted-2.3.3-9, mesa-libGL-6.5-13.1.fc6

I also have mesa-libGL-6.5-13.1.fc6 installed.

I tried this with SELinux off and with it on. I get the error with enforcing but not with permissive.

metacity: error while loading shared libraries: libGL.so.1: failed to map segment from shared object: Permission denied

It works with enforcing off for me.

/var/log/audit/audit.log contains denials. The execmem limitation is the problem stated from past discussions. It was stated that a program is bad if it needs execmem. That was the last discussion I heard about this error. There were no mesa-libGL package upgrades that I noted since the error started.
