[Bug 439476] Re: After switching from external to laptop screen, graphics are very slow

 

** Description changed:

  Binary package hint: xorg
  
  I sometimes boot my laptop with the lid closed and a monitor plugged in.
  X correctly identifies this setup and uses only the external monitor. If
  I unplug the external monitor, and then open the laptop, the resolution
  seems to be set correctly, but everything moves at about 0.2 fps. The
  mouse moves fine, but the screen only redraws every few seconds. It
  seems like everything is running fine... the effects work, music plays.
  But the screen only updates itself every few seconds. Restarting compiz
  did nothing. I have to log out and back in.
