Description of problem:
1. nvidiactl seems to generate regular X errors (I am using nvidia drivers)
type=AVC msg=audit(1198522354.106:3297): avc:  denied  { execmod } for  pid=7804
comm="ffmpeg" path="/usr/lib/libswscale.so.0.5.0" dev=sda7 ino=967679
scontext=unconfined_u:system_r:unconfined_t:s0-s0:c0.c1023
tcontext=system_u:object_r:lib_t:s0 tclass=file

2. I also get selinux X errors when running vmware server:
