  Binary package hint: xorg
  
  Hello,
  
  I discovered a quiet annoying error in Ubuntu 9.10 Karmic on my Lenovo
  Thinkpad T500 notebook.
  
  From time to time (but serveral times a week) when I close and reopen
  the lid sometime later the display is not reactivated. It is totally
  dark, so maybe not a screensaver problem. I closed and reopened the lid
  several time in case of a problem with electonic contacts or so but the
  display remains black.
  
  Best regards!
