[Bug 462765] Re: [karmic] Detaching secondary monitor causes very slow X performance

 

** Description changed:

  Binary package hint: xorg
  
  When I have a second monitor attached, and turn off that monitor in
  preferences, everything starts drawing on the screen _very_ slowly
  (though X is not frozen). I SSHd into my laptop and ran top to see if
  any processes were consuming lots of CPU power, but everything looked
  normal there. If I open up TTY1, the performance in X stays crappy, but
  if I open up TTY1 _and_ log in there, the performance returns to normal.
