If I try to terminate X while I'm in it, it just "hangs" -- I have to switch to the vty, ctrl-c it, wait, then blindly key in a reboot to get my system back up. IIRC, this started happening after I upgraded to Xorg 7.4. I thought that Mattia might be doing the same thing as a work-around for the freezing intel-driven display thing, thus the X-to-vty switch "fix" of disabling msi... -Brandon
