After upgrading from LMDE6 to LMDE7, the greeter screen (at VT7) is not shown automatically, but I must press Alt+F7 to switch from VT1 to VT7.
I compared /var/log/lightdm/lightdm.log with a working machine and the only difference is in this section:
[+0.02s] DEBUG: Launching process 2004: /usr/bin/X :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
[+0.02s] DEBUG: XServer 0: Waiting for ready signal from X server :0
[+0.02s] DEBUG: Acquired bus name org.freedesktop.DisplayManager
[+0.02s] DEBUG: Registering seat with bus path /org/freedesktop/DisplayManager/Seat0
[+0.02s] DEBUG: Loading users from org.freedesktop.Accounts
[+0.02s] DEBUG: User /org/freedesktop/Accounts/User1000 added
[+12.77s] DEBUG: Got signal 10 from process 2004
On a working machine, the last line happens automatically (within a second), but on my machine it only happens after I press Alt+F7.
Does anyone have any idea how to fix this ?
