Moving mouse while laptop lid is closed turns on screen

[Ben Maurer]

On a laptop, I closed the lid of my computer and them moved the mouse. The
screen quite obviously lit up. It should stay dark, as there is no way anyone
could see it when the lid is closed.

Noticed this because I have an optical mouse and I bumped my desk and saw the
light go on.

I'm going to upload 0.0.15 - could you test with this one?

Didn't help as far as I could tell...

I have the same issue on the Dell Latitude X1.

i think gnome-power-manager must be taught to make the system ignore events while the lid is shut, marking as whishlist and cross-assigning to gnome-power-manager

ogra: you are bang on, g-p-m has to be taught to ingore DPMS control events when the lid is shut. This is quite easy to do in the current framework.
src/gpm-manager.c (idle_changed_cb): needs patching. I'll have to test this on another laptop, as my toshiba supports hardware blanking, and so does not wake-up when I move my mouse.
Give me a few days, and I'll attach a patch -- Ben, are you able to test a patch against CVS or do I need to test this locally first?
Thanks.

Should be fixed in CVS:

2006-03-02 Richard Hughes <email address hidden>
 * src/gpm-manager.c: Ignore timeout events when the lid is closed, as the DPMS is already off, and we don't want to perform policy actions or re-enable the screen when the user moves the mouse (on systems that do not support hardware blanking).

Thinking about this more, the screensaver may come on when the lid is closed, but this wasn't the problem of the original bugreport. I guess g-p-m should inhibit the screensaver when the lid id closed.

[Richard Hughes (richard-hughes)]

I've just committed this:

2006-03-02 Richard Hughes <email address hidden>
 * src/gpm-screensaver.{c|h}: Add the functions: gpm_screensaver_inhibit_activation() and gpm_screensaver_allow_activation ().
 * src/gpm-manager.c (lid_button_pressed): Inhibit activation of the screensaver when the lid is closed, and allow activation when the lid is opened. This prevents the screensaver starting when the panel is closed.

You guys owe me a beer :-)

Richard.

granted :) thanks so much

should be fixed in 2.13.92+CVS20060302-0ubuntu1

Just want to point out that this fix causes troubles for everyone using docking stations or the like. Using your laptop with external monitor and keyb/mouse while having lid closed.

Caused by this "fix", the scenario just described will not allow external monitors to get blanked or "screensaved" when lid closed!
