For this last objection, you can either edit your /etc/sudoers file
(using visudo) to give you permission to run the command without a
password, or use kdesu instead of sudo.  That will give you a
graphical password box.

But I think a better solution is to check out one of the low latency
kernels and see if you can just fix the responsiveness on your new
machine.  It really should not be hiccupping.
