Package: gdm3 Followup-For: Bug #801749 After upgrading to current testing/stretch, the problem disappeared.
The versions for gdm3 and gnome-shell did not change from my previous mail. There are 2 messages left in dmesg, but they appear only once: <log src="dmesg"> [ 53.168027] systemd-logind[2456]: Failed to start user service, ignoring: Unknown unit: user@107.service [ 53.181329] systemd-logind[2456]: New session c1 of user Debian-gdm. [ 86.052490] systemd-logind[2456]: Failed to start user service, ignoring: Unknown unit: user@1000.service [ 86.058723] systemd-logind[2456]: New session 2 of user r3vlibre. </log> So, there is something that must have been fixed, but I don't know what was broken, since I didn't change the configuration before it started to fail.
