Public bug reported:
Binary package hint: gnome-power-manager
Expected:
GPM should allow my external monitor to enter DPMS suspend while the laptop lid
is closed.
Observed:
GPM doesn't allow my external monitor to suspend while the lid is closed on the
laptop. If the lid is open, it works fine.
Steps To Reproduce:
Restart Ubuntu with the laptop lid closed, log in and wait for the timeout
period. The external monitor shows the screensaver, but does not enter DPMS
suspend.
No combination of GConf options has allowed me to effectively work
around this issue. In another bug, someone wrote a perl script that
works, but only if the screensaver is enabled. I use the machine with
the screensaver both on and off. So, I started digging.
Here's some snipped GPM logs (gnome-power-manager --verbose):
(Lid down, 00:01 timeout for screensaver and dpms blanking, does not work as
expected)

I also went digging in gpm-manager.c from GPM to figure out what that
'lid is closed...' stuff meant:
8<--- snip --->8
/* Ignore back-to-NORMAL events when the lid is closed, as the DPMS is
* already off, and we don't want to re-enable the screen when the user
* moves the mouse on systems that do not support hardware blanking. */
if (gpm_button_is_lid_closed (manager->priv->button) &&
mode == GPM_IDLE_MODE_NORMAL) {
egg_debug ("lid is closed, so we are ignoring ->NORMAL state changes");
return;
}
8<--- snip --->8
... but I haven't been able to relate it directly to my problem, because
I want it to blank in the first place. It was the only big difference I
could spot in much of the logging.
Thanks!
