Hi

I am getting following error when starting X as normal user :

Build Operating System: Linux 2.6.27.10 i686
Current Operating System: Linux host.webofunni.com 2.6.27.10 #1 SMP PREEMPT
Wed Dec 24 21:37:14 CET 2008 i686

(WW) xf86OpenConsole: chown /dev/tty0 failed: Operation not permitted
xf86EnableIOPorts: failed to set IOPL for I/O (Operation not permitted)

I am able to start X as root and using xfce as desktop interface. Please
help.

Are you running with selinux enabled?

Is Xorg setuid to root?

sudo chown root $prefix/Xorg
sudo chmod u+s $prefix/Xorg

Dan,

setuid was not set. I have set that and X is working now.

bash-3.2$ ls -l /usr/bin/Xorg
-rwsrwxrwx 1 root root 1563180 Feb 19 15:31 /usr/bin/Xorg
bash-3.2$

Thanks for the solution :-)
