No problem with this PC. I did have a matlab issue using lots of cpu with java machine which is why I rebooted, that was a minor irritant. > > Is the reboot hang related to the xorg update issue? As I can't access this PC remotely (I can't ping it), any suggestions on how I fix this? This sounds like the problem I'm having with my laptop, which seems subtly different from the xorg issue. I can boot to runlevel 3 (or for me better level 1) as zxq9 describes, Pat's sugggestion of dropping " rhgb quiet" at the end of the boot command helps too, but I seem to get stuck when I bring the network up - NetworkManager is a suspect. -- Dr. Andrew C.
