It just might be that the login manager is doing some weird thing the new Xorg can't allow anymore. I get the same kind of error when using bumblebee: bumblebeed[529]: [19535.167046] [ERROR][XORG] (EE) systemd-logind: failed to get session: PID 10552 does not belong to any known session I can use the Xorg server without any problems though. Any other useful log? Also, are you checking the system journal instead of only the user one? -- Mateus Rodrigues Costa
