I am using Linux Mint Debian Edition 2 with MATE desktop, and I upgraded it to Debian testing repository.

When I press Shutdown or Restart from within MATE desktop, it only logs out, and goes back to MDM (mate display manager) login screen

I tried replacing mdm with slim, but that did not make any difference.

I checked /var/log/messages but there was no errors or any particular log at that time. Only something like this:

Oct 13 19:27:16 saeedgnu-lenovo ag[3076]: mdm-superinit Starting...
Oct 13 19:27:16 saeedgnu-lenovo ag[3077]: mdm-superinit Finished

I also added acpi=force to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and ran update-grub, still no difference.

My machine is a Lenovo Flex 2 laptop (core i7)

My kernel:

$ uname -a
Linux saeedgnu-lenovo 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt7-1 (2015-03-01) x86_64 GNU/Linux11

Is there anything else I can check?

Thanks in advance

  • @FrankThomas yes, it is – saeedgnu Oct 13 '15 at 21:08

Problem solved by running this command

sudo ln -s /usr/lib/x86_64-linux-gnu /usr/lib/polkit-mate

I copy my home directory after each Linux installation, even though my old system was Linux Mint too, I think the command for policykit was changed after upgrading the system (from /usr/lib/polkit-mate/polkit-mate-authentication-agent-1 to /usr/lib/x86_64-linux-gnu/polkit-mate-authentication-agent-1). So the policykit deamon was not starting after login.
