LXDE can't shutdown or reboot

qrange · 11-29-2013, 06:11 AM

I can't shutdown LXDE using 'logout' button. (nothing happens)
/var/log doesn't seem to contain any errors.

~/.cache/lxsession/LXDE contains this error:

Code:

(lxsession-logout:10421): GLib-GIO-CRITICAL **: g_dbus_proxy_call_sync_internal: assertion `error == NULL || *error == NULL' failed

(lxsession-logout:10421): GLib-CRITICAL **: g_variant_unref: assertion `value != NULL' failed

using latest Debian testing amd64.
thanks.

Have you tried to do this from terminal as root?

Code:

halt

Did this just occur recently?
I ask because I had a similar issue (though it may be unrelated) and I worked around it by using gdm3 as my display manager rather than lightdm. I'd prefer lightdm in some ways but I like the way gdm3 looks in Debian now so I'll leave it as it is.

Apologies if it is unrelated.

sorry I forgot to mention that poweroff and similar work.

Well that means the involved files are correct anyway.

As Lxde is Open Box based you should be able to check the file for the shutdown menu (logout or what ever). I believe that would be where your problem is.

I can't remember where OB stores that file let alone Lxde. One option would be to write a little script and put it in your menu with the options you want on it.

Does Lxde use the obmenu package? If so you should be able to check the man page for that and get some info.

I haven't had a Debian Lxde install on here for a while and the OB install I have is on here is not what I am using normally. I have a calculation running right now that will not finish until morning. If you haven't solved this by then I will pop over there and see what I can find that may help.

I really need to look into this further. I know I had a script you could add to the OB menu, would think you could do the same for whatever Lxde uses.

But turns out that my menu in Debian OB Sid (because it is Sid OB I can use the label SOB - I may be a grumpy geezer but that doesn't mean I ever grew up) only has "Exit" in it and it just logs you out. This works out because you do have the option of shutting down or rebooting from the Login screen but seems rather strange.

Lxde probably uses the OB menu or one of their own. Should be in a similar location. The obmenu that I edited is located;
/home/tom/.config/openbox/menu.xml

I added 2 entries below the Exit entry;

Code:

		<item label="Exit">
			<action name="Exit"/>
		</item>
                <item label="Reboot">
			<action name="Execute">
				<execute>gksu /sbin/reboot</execute>
			</action>
		</item>
                <item label="Shut Down">
			<action name="Execute">
				<execute>gksu /sbin/halt</execute>
			</action>
		</item>

Problem with that is that I am using gksu to run the command so am asked for my root password.

They both work though very well.

Never noticed that before. This is not an old install. It is on an external I formated with a GPT partition system to try it out (love it) and have mainly been doing things in terminal on here so just type reboot when I am ready to leave.
