OpenOffice.org (OOo) 2.3.0 is incompatible with the SELinux technology activated by default in Fedora 7, Fedora Core 6 (and older) and Red Hat Linux system (and, optionally, in other Linux-based systems): see http://www.openoffice.org/issues/show_bug.cgi?id=80816 for more information and current situation.
Symptoms:
If OpenOffice.org is started from the GUI, it simply doesn't start.
If OpenOffice.org is started from the command line, the error message no suitable windowing system found, exiting. is displayed and OpenOffice.org exists immediately.
The best resolution so far consists in setting the proper security context: execute (as root or with sudo privileges)
# chcon -t textrel_shlib_t libvclplug_gen680li.so.1.1
in the program directory in your OOo installation.
A more radical resolution is disabling SELinux altogether (requires root/sudo privileges):
Command line (as root): # setenforce 0
GUI: System -> Administration -> Firewall and SELinux -> set "Permissive" mode.
Note that, with the default configuration, SELinux will be restored in "Enforcing" mode upon reboot or installation of a new kernel if you change it via the command-line utility.
