I am experiencing a problem with remote X seesions. I have installed the NX client and server; I have no problem opening up a remote xsession on my server. However, there are a number of applications (firefox for one) that will not start on my remote terminal unless I launch them as a super user. I've experienced this before - in that case it was a matter of editing seLinux settings (it was under Fedora I think). The problem had to do with execute permissions for remote clients - I can see how to affect these settings for apparmor. Any help would be greatly appreciated.
