It costs me several hours to debug why systemd user session fail to start. Even I created these cgroups and chmod their files to 777, it less permission to write, so the "systemd --user" fail with "Permission denied". The workaround so far is add kernel cmdline option "security=none". -- Thanks, Chengwei > Failed to allocate manager object: Permission denied > Failed to allocate manager object: Permission denied > dbus[178]: [system] Rejected send message, 2 matched rules; > type="method_call", > sender=":1.5" (uid=5000 pid=220 comm="(sd-pam) ") > interface="org.freedesktop.l > ogin1.Manager" member="ReleaseSession" error name="(unset)" > requested_reply="0" > destination="org.freedesktop.login1" (uid=0 pid=180 > comm="/usr/lib/systemd/syste > md-logind ") > [system] Rejected send message, 2 matched rules; type="method_call", > sender=":1. > 5" (uid=5000 pid=220 comm="(sd-pam) ") > interface="org.freedesktop.login1.Manag > er" member="ReleaseSession" error name="(unset)" requested_reply="0" > destination > ="org.freedesktop.login1" (uid=0 pid=180 > comm="/usr/lib/systemd/systemd-logind " > ) > pam_systemd(login:session): Failed to release session: Access denied > pam_unix(login:session): session closed for user app > Started User Manager for app. > Started User Manager for 5000. > Stopped Collect Read-Ahead Data. > Started Load Kernel Modules. > Mounted Configuration File System. > Started Set Up Additional Binary Formats. > Stopping Session c1 of user app. > Stopped Session c1 of user app. > ======================================= > > Version info: > tizen-mobile-session (provides [email protected]) version: 1-3.1, commit > number is 9e1de416dfc4c6e0a3ff110b70722b6e9cfef450, tag is > submit/tizen/20131213.101720 > systemd version: 208, commit number is > 6b31acecb8f412f7843951e6f3bacc7d8b516f42, tag is submit/tizen/20131218.205849 > > I am not familiar with systemd mechanism, any comments and hints are > appreciated. > > Thanks > > > > > > _______________________________________________ > Dev mailing list > [email protected] > https://lists.tizen.org/listinfo/dev
