FYI, relevant patches can be found here: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=35305 The problem is that the service is unable to start a session. After login, lightdm just black screen and restart. Looking at logs, the only relevant problem I was able to find is from pam. It says something like: `pam_elogind[...] Failed to release session: No session 'cN' known` Also, an issue was posted recently upstream about window managers not being able to find Xauthority if XAUTHORITY environment variable is set. See https://github.com/CanonicalLtd/lightdm/issues/68 . But I'm not sure it's relevant her. So if anyone has a lead, please share it! :) Have a nice day, L p R n d n
