I have a Raspberry Pi running Raspbian. Towards the end of the startup log, I see this error. I believe it has been there a while, and I'm not sure what it may imply. kernel: bcm2708_fb soc:fb: Unknown ioctl 0x40187a22It is included around the launch of lightdm. Here is the log section:Nov 27 13:20:30 raspberrypi lightdm[619]: ** (lightdm:619): WARNING **: Error getting user list from org.freedesktop.Accounts: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktNov 27 13:20:30 raspberrypi systemd[1]: Started Light Display Manager.Nov 27 13:20:31 raspberrypi kernel: bcm2708_fb soc:fb: Unknown ioctl 0x40187a22Nov 27 13:20:31 raspberrypi kernel: cfg80211: Calling CRDA to update world regulatory domainNov 27 13:20:32 raspberrypi lightdm[619]: ** (process:670): WARNING **: Error getting user list from org.freedesktop.Accounts: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktNov 27 13:20:32 raspberrypi lightdm[670]: pam_unix(lightdm-autologin:session): session opened for user XX by (uid=0)I should perhaps note that the default user pi doesn't exist anymore, why lightdm may be complaining about doing stuff for uid=0.
