I just upgraded from FC3 to FC4 via yum. Followed some instructions etc... Install was fine no problems. Before the install I disabled SeLinux. Once the install was complete and I booted FC4 I then enabled SeLinux and then rebooted. After boot ( by the way it booted just fine.) I logged into the system and received an error. It told me X could not be started. I tried as root with the same result. I tried ssh and the kitched sink. I then rebooted and modified grub (selinux=0) and all is fine. What just happened here? Do I need to re-install? Is something broken ? Thanks in advance.
