After running 'xset dpms force off' with lid closed on a laptop to disable the backlight, moving the mouse or touching the keyboard will cause the backlight to turn back on. The backlight should never turn on under any circumstances when the lid is closed, unless maybe in the case that the user runs 'xset dpms force on' explicitly.

[Ubuntu-x-swat] [Bug 41994] Re: closed Laptop Lid to reliably keep Backlight off
Ah, sorry, done a little more testing. It stays off indefinitely (without input) if the lid is open. But, if I run it after closing the lid, it still wakes randomly. This means that it must be receiving some imaginary input when the lid is closed to wake it. My biggest problem is that some imaginary input wakes the laptop. Ignoring all input while the lid is closed would solve the problem. However, without a mouse connected I can't provide any input with the lid closed anyway, so this doesn't bother me as much as not waking on imaginary inputs. I remember trying to debug this before, and the input is non-existent. The screen wakes because the X server is no longer idle, but using xev reports no input being received. It is interesting that this only happens when the lid is closed. Perhaps this bug should be split into two parts. Firstly, a bug, that imaginary input is received randomly when the lid is closed. Secondly, a wishlist, that the screen should not wake on input while the lid is closed. Fixing either of these would satisfy me. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to x11-xserver-utils in Ubuntu. https://bugs.launchpad.net/bugs/41994 Title: closed Laptop Lid to reliably keep Backlight off To manage notifications about this bug go to: https://bugs.launchpad.net/dell/+bug/41994/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I can blank the screen using the command "xset dpms force off", and it doesn't turn back on.

I have found a gnome-shell extension which adds a menu item to blank the screen. This seems to work perfectly, perhaps the code used in there can be used when the laptop lid is closed?
