** 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
