Is SUID status for XFree86 disabled?
The XFree86 program is the X server binary in XFree86 4. For ordinary users to run X, this binary (or a world-executable wrapper) must be Set-UID root. In this system's case, the XFree86 binary is Set-UID. This program does not need to be Set-UID if you won't be using this machine as a graphical workstation at all. One specific case where you can very safely answer yes is when this system will be running without a monitor of any kind.
