Karmic - Can't DISable suspend or hibernate

[dnairb]

In Jaunty, and other previous releases, it was a simple exercise to disable suspend and hibernate, using the gnome configuration editor:

apps -> gnome-power-manager -> general

and unchecking can_hibernate and can_suspend options.

The "Shutdown the computer" window then only has "Shutdown" and "Restart" as the available options.


In Karmic, however, this doesn't work. Suspend and Hibernate are still options in the shutdown/restart window.

Any ideas?

Yeah I'd like to disable suspend as well, as it does weird things to my system. I haven't been able to find a workaround.

This bug is on Launchpad though. It's Confirmed and has Medium Importance, so let's hope a fix will come soon.

Thanks for the pointer Geert.

I see that the bug is as yet not allocated.

i think gnome-power manager sucks big time. In my opinion, it need a complete overhaul. Heck, i switched to KDE to escape that thing! It doesn't even have profile support! All u desktop users dont care, but for all the laptops, its a pain in the butt.

I found a way to prevent the system from suspending and/or hibernating. The suspend/hibernate options still show up in the menu but if you click on one of them it just locks the screen.

You just need to edit: /usr/share/polkit-1/actions/org.freedesktop.devicekit.power.policy

And change the

<allow_active>yes</allow_active>

entries for suspend and/or hibernate to

<allow_active>no</allow_active>

So it should look something like this:

 
  <action id="org.freedesktop.devicekit.power.suspend">
    <description>Suspend the system</description>
    <message>Authentication is required to suspend the system</message>
    <defaults>
      <allow_inactive>no</allow_inactive>
      <allow_active>no</allow_active>
    </defaults>
  </action>

  <action id="org.freedesktop.devicekit.power.hibernate">
    <description>Hibernate the system</description>
    <message>Authentication is required to hibernate the system</message>
    <defaults>
      <allow_inactive>no</allow_inactive>
      <allow_active>no</allow_active>
    </defaults>
  </action>

Then you will probably need to restart your machine for the changes to take effect.

the above-mentioned workaround works for me on a fresh install of karmic.

a little suboptimal, inasmuch as the hibernate option is still there even if 'disabled', but even so i'd rather have it lock the screen than freeze the comp, if i accidentally click on it.

thanks marshallium for posting it.

marshalium's tip is correct. Thank you.

You can only change the text as root, so the terminal command is:

gksudo gedit /usr/share/polkit-1/actions/org.freedesktop.devicekit.power.policy

--edited: removed a wrong assumption--

[nanotube]

marshalium's tip points in the right direction, but it's not entirely complete, I think.

I think you should not only change this line from "yes" into "no":
<allow_active>yes</allow_active>

but also the line above, from "no" into "yes"!
<allow_inactive>no</allow_inactive>

hmm, i only changed allow_active from 'yes' to 'no' and everything worked...

what in particular didn't work for you when you didn't set allow_inactive to yes?

[Pjotr123]

I only applied "my" version, which works fine on my machines....

I'm not sure, but it seems logical to not only forbid "active", but also allow "inactive". The one implies the other. Otherwise you forbid hibernation to be *active*, and also to be *inactive*! A logical impossibility. That feels wrong.

As I said, I'm not sure. I'm acting solely on my "Linux intuition", which may be quite wrong in this case, of course. However, "my" version works fine, so it's probably not wrong to edit the second line. Superfluous at most, but not wrong.
