g-p-m postinst should use 'pmi capabilities' to seed can_suspend

Bug #47303 reported by Philipp Kern on 2006-05-29
Affects Status Importance Assigned to Milestone
gnome-power-manager (Ubuntu)

Bug Description

I just installed Dapper from scratch on an iBook through its installer. There are no menu items regarding suspend-to-RAM shown in the Gnome logout dialog. As I cannot just modify /etc/default/acpi-support due to acpi-support being !powerpc, it remains very unclear how to proceed.

Pitti suggested on IRC that a recent g-p-m upload broke it for new installs.

What happens if you go:

  System->Preferences->Power Management
  General->Sleep Button Action = Suspend.

gnome-power-manager is utterly, utterly broken in this respect:


  case "$1" in
        if [ -r /usr/share/acpi-support/device-funcs ]; then
           . /usr/share/acpi-support/device-funcs
        if [ "x$ACPI_SLEEP" = "xtrue" ]; then
            gconftool-2 --direct \
                        --config-source xml:readwrite:/var/lib/gconf/defaults \
                        --set --type bool \
                        /apps/gnome-power-manager/can_suspend true

...otherwise, it sets it as false. g-p-m doesn't even call 'pmi capabilities' to enquiry...

Changed in gnome-power-manager:
status: Unconfirmed → Needs Info
status: Needs Info → Confirmed

I did a manual edit of the can_suspend gconf key yesterday after I reported the bug. The machine did suspend and wake just fine, still a bubble is shown that "the machine failed to suspend correctly".

Changing the Sleep Button Action shows the same "Do you really want to enable Suspend" dialog like when I toggle can_suspend in gconf-editor. I do not have a sleep button, though and the power button just toggles the generic Quit dialog. Suspend on lid close doesn't yet work neither.
