Bug Description

Binary package hint: gnome-power-manager

My laptop (a Dell Inspiron 6000) has multimedia buttons on the front that can be used when the lid is closed. My g-p-m settings are to blank the screen when the lid is closed.

However, when I press the button (e.g. the volume) with the lid closed, I can see the screen turn back on inside the laptop. What's worse is that it never turns back off after that, even after the customary screensaver delay.

Duplicate bug #107399 reports the same behavior when moving an external mouse.

Steps to reproduce:
1. Set g-p-m to blank the screen with the lid closed.
2. Close the lid.
3. Press a multimedia button, move an external mouse, etc.
4. Wait for the screensaver to turn on and/or the screen to turn off; no response.

gnome-screensaver should query the lid status before disabling itself

bug still relevant in 7.04 Feisty Fawn

don't think this is a screensaver problem as much as a power-management problem. When I look at the Power History it shows that closing the lid initiates DPMS Off but when pressing the multimedia buttons the computer changes to DPMS On, turning on screen. only later when i open my laptop lid does it show that the laptop lid is opened. unlike the original post though, my screen eventually goes black as set to do, although not sure about timing.

basically,
DPMS should not be set On when lid is down on laptop and multimedia buttons are pressed.

different behavior may be desired on desktop such that the screen does come on when keys are pressed, but on a laptop as long as the lid is closed the screen should not be initiated until opened

I can confirm this with an Apple MacBook and remote control. Closing the lid initiates DPMS Off, pressing buttons on the remote (mapped to XF86Media* multimedia keys) causes DPMS on.

I agree it seems to be g-p-m, not gnome-screensaver, that's doing this. All I could do to mitigate it is to set the time-out for blank screen on gnome-screensaver to a lower value, doesn't exactly solve the problem though.

Just a note for the reproduction steps, this is best observed when g-p-m is not set to lock the screen on lid close.

This is happening for me running Kubuntu gutsy (with Feisty kernel) on a Dell Inspiron 1521. This seems related to Bug #107399. I think it's more likely an X, or X-driver problem. I'm using fglrx

Confirmed on two bugs with a variety of video hardware (thus ruling that out). I'm taking Matthew's word for it that it's a gnome-screensaver problem and reporting it upstream. (Thanks for the direction, Matthew.)

I filed bug #107399 and I use Kubuntu and KDE, so my issue at least is definitely not Gnome related.

This also happens within kubuntu 7.10.

Perhaps, or it simply affects the same packages on both sides (e.g. gnome-screensaver and kde-screensaver). I don't know enough off the top of my head to say, but I'm going off of Matthew Garrett's word, who changed the affected package, as to the source of the problem.

I have exactly the same problem on a Dell Inspiron 1525. I use Ubuntu Hardy with every package up to date.

Still is current on kubuntu intrepid. Using the media buttons on a Dell Inspiron 1521 turns the screen on.
