SELinux denied an operation requested by $SOURCE, a program used
to alter video hardware state.  This program is known to use
an unsafe operation on system memory but so are a number of
malware/exploit programs which masquerade as vbetool.  This tool is used to
reset video state when a machine resumes from a suspend.  If your machine
is not resuming properly your only choice is to allow this
operation and reduce your system security against such malware.
