Hello, I'm not 100% sure this is the cause, but these are the last messages I have before I rebooted: --8<---------------cut here---------------start------------->8--- Nov 23 01:09:14 localhost dbus-daemon[383]: [system] Activating service name='org.freedesktop.login1' requested by ':1.17' (uid=0 pid=370 comm="/gnu/store/ximad0zvg12r4x0x80mvym8hzg0n33jl-shadow") (using servicehelper) Nov 23 01:09:14 localhost elogind[1189]: elogind is already running as PID 390 Nov 23 01:09:20 localhost shepherd[1]: Respawning term-tty1.

Nov 23 01:09:39 localhost dbus-daemon[383]: [system] Failed to activate service 'org.freedesktop.login1': timed out (service_start_timeout=25000ms) --8<---------------cut here---------------end--------------->8--- I don't remember if I saw the slim login screen; but in any case I couldn't successfully login even via a ptty. It may have to do with polkit. To be investigated. This happened on a system *not* using gdm (it uses slim) and with ratpoison as the WM, on commit f42bc604547d9ee8e35fcd66d5db7786954cfac3 of the core-updates-frozen branch. To be investigated. Thanks, Maxim
