** Changed in: linux (Ubuntu)
   Importance: Undecided => Medium
       Status: Confirmed => Triaged

** Description changed:

  When I close the lid, its state as reported by
  /proc/acpi/button/lid/C1E5/state changes to "closed"; however, when I
  open it again, it stays at "closed", which keeps ACPI executing lid
  events which blank the screen every few minutes (I suspect that whenever
  a thermal event is received) and make it impossible to work. I have to
  reboot to reset the lid state back to open.
  
  I am using an up-to-date Kubuntu Hardy beta, but have observed this
  behavior since Gutsy (linux-source-2.6.22) on both Ubuntu and Kubuntu.
  The computer is an HP-Compaq nc6120, with an Intel Centrino 2GHz CPU.
  
  Attached find the output of dmesg in my system.
+ 
+ 
+ possible WORKAROUND (from http://tinyurl.com/38frty):
+ echo 1 | sudo tee /proc/acpi/video/*/DOS
