 |
|
Hi,
For several years, I use my own script to Inhibit/UnInhibit power management by ssh, to disable automatic suspend during update process. All work fine (initiated here viewtopic.php?f=66&t=118646)
Now, I'm installing a new laptop, always with gentoo.
Locally, I can do :
| Code: | | inhibit_cookie=$(qdbus org.freedesktop.PowerManagement.Inhibit /org/freedesktop/PowerManagement/Inhibit Inhibit "suspend" "need") |
to Inhibit.
Then | Code: | | qdbus org.freedesktop.PowerManagement.Inhibit /org/freedesktop/PowerManagement/Inhibit UnInhibit $inhibit_cookie |
to UnInhibit.
But, if I do it by ssh, I get | Code: | Cannot find '.Inhibit' in object /org/freedesktop/PowerManagement/Inhibit at org.freedesktop.PowerManagement.Inhibit
Service 'org.freedesktop.PowerManagement.Inhibit' does not exist. |
My simple code to test is :
| Code: | christophe@svs15 ~ $ cat /home/christophe/tmp/test.sh
#!/bin/bash
export DISPLAY=":0"
echo "$USER"
inhibit_cookie=$(qdbus org.freedesktop.PowerManagement.Inhibit /org/freedesktop/PowerManagement/Inhibit Inhibit "suspend" "need")
echo $inhibit_cookie
qdbus org.freedesktop.PowerManagement.Inhibit /org/freedesktop/PowerManagement/Inhibit UnInhibit $inhibit_cookie |
And I call it from another PC with :
| Code: | | ssh -x christophe@svs15 /home/christophe/tmp/test.sh |
That's not a problem with the USER, the command, or the script because all of this work on others PC, and /home is a nfs mount.
So that's a problem with my new install, and I can't find what I've forgot. Surely something very stupid.
consolekit and dbus services running (And inhibit *works* locally in my plasma session)
May be can you help me to find what is not normal with dbus.
Thanks for you help.
[EDIT] Another thing not working, surely about dbus too :
| Code: | christophe@svs15 ~ $ notify-send "text"
christophe@svs15 |
works fine, immediately
| Code: | root@svs15 ~ # su - christophe -c "notify-send text"
root@svs15 ~ # |
waits 35 secondes and doesn't notify anything. With or without DISPLAY=:0.0 |

Another thing I can note, maybe not important, is that on each PC where all is fine, I have same print-pid and print-adress for each dbus-daemon process :
| Code: | root@cored ~ # ps axfu | grep print-pid | grep -v grep
sddm 3026 0.0 0.0 35100 2372 ? Ss mars26 0:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
chris 3190 0.0 0.1 36324 4092 ? Ss mars26 0:02 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
root 18567 0.0 0.0 34960 2508 ? Ss 14:43 0:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session |
| Code: | root@medion ~ # ps axfu | grep print-pid | grep -v grep
sddm 1669 0.0 0.0 35100 2356 ? Ss mars22 0:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
regine 1697 0.0 0.1 36364 4312 ? Ss mars22 0:01 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session |
and on this one, they are different :
| Code: | root@svs15 ~ # ps axfu | grep print-pid | grep -v grep
sddm 1731 0.0 0.0 35264 2676 ? Ss 17:19 0:00 /usr/bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session
christo+ 1803 0.0 0.0 35232 2780 ? Ss 17:20 0:00 /usr/bin/dbus-daemon --fork --print-pid 6 --print-address 8 --session
christo+ 1827 0.0 0.0 35488 3076 ? Ss 17:20 0:00 /usr/bin/dbus-daemon --fork --print-pid 6 --print-address 8 --session |
Is it normal ? |

More simple, X session opened each time, /home is a nfs mount, centralized authentication with ldap :
| Code: | $ ssh regine@medion "qdbus org.freedesktop.PowerManagement"

/MainApplication
/local
/local/org_kde_powerdevil

/org/kde/Solid/PowerManagement/Actions/SuspendSession
/org/kde/Solid/PowerManagement/PolicyAgent |
| Code: | $ ssh regine@svs15 "qdbus org.freedesktop.PowerManagement"
Service 'org.freedesktop.PowerManagement' does not exist. |
diff medion://etc and svs15://etc doesn't show anything really different to explain that. |
