Setting Environment variables without autologin/user-session@.service

If you're not using auto-login, specifically the user-session@service, the environment variable DBUS_SESSION_BUS_ADDRESS needs to exported to something like export DBUS_SESSION_BUS_ADDRESS=/run/user/$(id -u)/dbus/user_bus_socket before systemd --user. Otherwise, an error shows up in journalctl : "systemd[3975]: Failed to open private bus connection: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11." Are there any other environment variables that need to be added to that section? Feynman (talk) 23:57, 5 February 2013 (UTC)

Not really. I'm not using auto-login and I'm not using any DE or login manager. It was a bug I believe on older versions on systemd. Since 198 it's not longer necessary. I still get that error on the start but it actually works without hassle. --Pabloxcl (talk) 16:21, 7 April 2013 (UTC)

Increasing priority of user services

How can I increase priority for user services? When I try to use CPUShares=2048, I get Failed to create cgroup cpu:/user/1000.user/2.session/systemd-536/xorg.service: Permission denied, when I try to use Nice=-15, I get Failed at step NICE spawning /usr/bin/xorg-launch-helper: Permission denied.
