Are you using systemd? If so, did you build sddm with USE=systemd? |
| 32 |
If not, did you build sddm with USE=consolekit and read the warning |
| 33 |
printed by portage? |
| 34 |
|
| 35 |
This display manager doesn't have native built-in ConsoleKit |
| 36 |
support. In order to use ConsoleKit pam module with this display |
| 37 |
manager, you should remove the "nox11" parameter from |
| 38 |
pm_ck_connector.so line in /etc/pam.d/system-login |
| 39 |
|

Your issue is most likely that your X session is not being treated as |
| 42 |
a login session by logind/ConsoleKit, and therefore your user is not |
| 43 |
being added to the ACLs on the various devices under /dev, including |
| 44 |
all sound devices, certain input devices, any CD/DVD/BR devices you |
| 45 |
may have, and certain video devices. |
