Subject: [PATCH 6/7] daemon: ensure is-initial bit is transferred to new login
|
|
|
795d2c |
screen at logout
|
|
|
795d2c |
|
|
|
795d2c |
At the moment, when a user logs out we call sync_seats to restart the
|
|
|
795d2c |
login screen. sync_seats doesn't know whether or not vt1 is occupied.
|
|
|
795d2c |
|
|
|
795d2c |
This commit changes the code to call the more targeted `create_display`
|
|
|
795d2c |
function, which we can inform of vt1's availability by the is_initial
|
|
|
795d2c |
flag.
