[SOLVED] xfce4 session (permission?) problem

TKH · 02-21-2013, 02:44 PM

Hi, I finished installing XFCE4.
Everything goes well except the ACPI functions.
In the log out box, everything is grey except for the logout button.
I installed XFCE4 with all the packages.
I have ConsoleKit, GNUPG, UPower, and every single deps mentioned in the xfce4-session page.

But nothing can work it out, not even my recently installed gnupg

Can someone help me with this?
Every word will be appreciated!

This happens when starting XFCE4 from the console. If you're logging in from a graphical login manager you may need to install the xfce4-power-manager package.

Check following processes/services:

Code:

~$ ps -aef | egrep "xfce4-session|xfdesktop|xfce4-panel|xfwm4"

If any of these not running, then manually invoke start them as:

Code:

~$ xfce4-session &
~$ xfdesktop &
~$ xfwm4 &
~$ xfce4-panel &

I start it from a console by running:

Code:

startxfce4

by the way, I notice that all of them works when I run it as root
which is why i mention permission

@shivaa
all of them are running

And that is normal. The power manager needs superuser privileges. That's why it works when you start XFCE4 as root.

When you use a graphical login manager, it escalates the power manager privileges. I think it does it through PAM, but I could be wrong.

Again, this is normal when you start XFCE4 from the console. So do I, but if I start it from a graphical login manager, the other buttons are available.

Try adding yourself to the power (or equivalent) group.

Did you try cmds I suggeted above? It won't need to be root to launch xfce-session.

Second, you can add your account to /etc/sudoers to take sudo access and launch any tool/utility.

OR, just for your info. (but not recommended) add your user account to main group of super-user. But take a note that, it will also require root privilages to modify your group(s):

Code:

~$ id -a root
~$ usermod -G <group> username

none of it works

i kinda think that it is the problem with ConsoleKit
this problem start after i installed that package

i tried running ck-list-sessions but nothing come out
also, i check that the /var/run/console does not exist

How can you say that none of these worked? Did you get any error message, if yes, please share it.

I think you need polkit installed, I had a similar problem but can't remember exactly what I did to fix it but I'm pretty sure it was polkit.

either polkit or CK, but i don't know what kind of problem

Okay, I found out that all of this mess is because of a simple goofy mistake.
I accidentally flipped some options of 'system-session' and 'system-password' line (the last ones) in /etc/pam.d/login.
It turns out good after I fix it.
Sorry for the trouble!
