Xfce Power Manager

Hey,

I am using an Ubuntu installation with Xfce as desktop environment on my Thinkpad E520. After installing updates (including a reboot) my power manager stopped working and I also get crash reports about the network manager on every start. I tried reinstalling (sudo apt-get remove, then install) xfce4-power-manager, but it didn't help. Here are some screenshots:

(The text says "Can't establish connection to the power manager for Xfce")

Any ideas how to fix this problem?

Hello themuCkk and welcome to the forums.

Is xfce4-power-manager running? You can check by typing in the following in a terminal window:

Code:

---

ps -ef | grep xfce4-power

---

There also might be some useful information in the ~/.xsession-errors log file.

Hello,

xfce4-power is running. The only related message in the log was this:

Quote:

---

(xfce4-power-manager-settings:3227): xfce4-power-manager-settings-CRITICAL **: Unable to get configuration information from xfce power manager: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Thanks for your fast reply :).

Try clearing out your sessions cache. Logout form Xfce, Ctrl+Alt+F1 to go to first tty, login to tty (text-based), clear the cache with:

Code:

---

rm -rf ~/.cache/sessions

---

...then go back to the GUI (Ctrl+Alt+F7) and log back in.

That solved it, thanks!

That helped me also. Thanks, Toz!

If the problem consists in thunar, right after login, waiting long time before opening home and doing it after error message (unspecified resource/directory not available), it seems solved by a small change in : /etc/nsswitch.conf.

The original line: [hosts: files dns]
when changed to: [hosts: files wins dns]

seems to solve the problem without further interventions.
Even the "Network" link in thunar works out of the box.

worked for me

This fix, although still valid, was necessary for earlier versions of Xfce. The later versions of Xfce (4.10+) including the version in 14.04 has added the ability to clear the sessions cache without the need to go to a text console. Look for it in Settings Manager >> Session and Startup >> Session tab >> "Clear saved sessions". It is much easier now to clear the saved sessions cache.
