My biggest complaint with the FC2 X hangs is that the keyboard is always 
"dead" (no response, can't change VC to a text window) and *most* of the 
time the mouse is "dead" as well; though I have had a couple of hangs in 
the middle of actively using X and the mouse motion remains, mouse 
clicks are not processed; but most have occurred while the system in 
idle and running a screensaver.  Its obvious because the screensaver 
stop changing.  The rest of the sysytem continues to run normally.  My 
http server still runs, I still get email, other processes continue to 
run.  During the X hangs, I have to login remotely, and top shows that 
the "X" process is chewing all of the otherwise unused CPU time (usually 
 > 85%), but is recoverable if the "X" process is killed (usually 
requires a "kill -9").  My frequency under FC2 is 1 hang every day or two.

I'm interested in knowing how these symptoms change in FC3....
