Hi All,

I would like to bring to your attention this:
I recently wanted to switch from XFCE to MATE.
I installed task-mate-desktop, but I noticed that suspend and shutdown were
missing and generally the system is not in the best state (i.e. no system
tray and other quirks).

I installed elogind and seemed to have solved some problems (suspend etc)
but when I try to install:

# apt-get install libpolkit-backend-elogind-1-0

Ok, so I tried:

# apt-get install libpolkit-backend-elogind-1-0 task-mate-desktop slim

slim is already the newest version (1.3.6-5.1+devuan2).
task-mate-desktop is already the newest version (3.39+devuan1.9).
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
slim : Depends: consolekit but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

and if I try:

# apt-get install libpolkit-backend-elogind-1-0 task-mate-desktop

How I can solve this? I am asking because I have other installation of mate
working with slim and elogind.
Sorry for the length of this email ant thanks in advance.
