[Bug 57872] Re: regression: pressing power button no longer brings up logout dialog

[Scott Bronson]

My laptop (IBM T-42p) suffers from this bug right now.  Edgy beta, gpm
v. 2.16.1-0ubuntu1.  While trying to fix it, I've just found something
rather startling...

- When I use the Ubuntu-compiled gpm, it never works.
- When I compile the Ubuntu sources myself, it works!  But there's a catch...


First, establish that Ubuntu's package never works:

0. killall gnome-power-manager
1. gnome-power-manager --no-daemon --verbose

The output demonstrates that gpm definitely sees the power button press
and calls gnome_client_request_save.  No matter how many times you push
the button, the push is noticed but nothing happens.


Now, watch a self-compiled package work but miss the first button push.

0. killall gnome-power-manager
1. apt-get source gnome-power-manager
2. cd gnome-power-manager-2.16.1
3. ./configure; make
4. cd src
5. ./gnome-power-manager --no-daemon --verbose

Push the button once.  Nothing happens.

Now push it again.  It works!  The shutdown dialog appears and
everything works hunky-dory.

Push it again.  It continues working.  After the first failure, it works
all the time.  If you kill and restart ./gnome-power-manager, it fails
once as before, then works all the time.  This is 100% reproducible on
my machine.

It doesn't appear to matter whether the self-compiled gpm is running as
a daemon or not.  Either way, it misses the first button push, then
notices every push after that.


NOTE: I have set "General -> When power button is pressed" to "Ask Me" because that's the only mode that I find useful.

NOTE2: it takes my computer a 3-count before it notices a push on the
power button.  This is disturbing because a 4-count causes it to power
off immediately.  It would be nice if gpm could provide more immediate
feedback.  I wonder if this causes some people to think that it's not
working at all -- they're just not pushing the button for long enough.

If anyone can suggest code modifications to try, I'm happy to give them
a whirl.  I'm getting somewhat familiar with this bit of code...
