Possibly fixed, and may need an SRU for older releases
lightdm (1.21.4-0ubuntu1) zesty; urgency=medium
* New upstream release:
- Use power management functions from ConsoleKit2 if available.
- Correctly pass return value from sessions to LightDM.
- Retry VT_WAITACTIVE if we get EINTR.
- Ignore SIGHUP by default.
- Use SA_RESTART with SIGPIPE.
- liblightdm-qt: Use liblightdm-gobject power methods instead of
re-implementing in Qt.
* debian/liblightdm-qt-3-0.symbols:
* debian/liblightdm-qt5-3-0.symbols:
- Add symbols files for C++ libraries

Title:
VT_WAITACTIVE does not work well with a multiseat setup
Status in Light Display Manager:
Incomplete
Status in lightdm package in Ubuntu:
Incomplete
Bug description:
Related to the fix introduced in bug #851612 .
Saw this in lightdm.log (system call interrupted because of ctrl-alt-del
pressed):
[+2.97s] DEBUG: New display ready, switching to it
[+2.97s] DEBUG: Activating VT 8
[+77.56s] WARNING: Error using VT_WAITACTIVE 8 on /dev/console: Interrupted
system call
[+77.56s] DEBUG: Got signal 15 from process 1
[+77.56s] DEBUG: Caught Terminated signal, shutting down
And in x-1-greeter.log:
[+0.48s] DEBUG: Loading users from org.freedesktop.Accounts
[+0.48s] DEBUG: Loading user /org/freedesktop/Accounts/User1001
[+0.50s] DEBUG: Loading user /org/freedesktop/Accounts/User1000
[+50.56s] WARNING: Error getting session list from
org.freedesktop.DisplayManager: Timeout was reached
On vt7, unity-greeter would get stuck after password input.
On vt8, unity-greeter appears after that "getting session list timeout",
which is about a minute later than vt7, and does not have a password input
field.
lightdm blocked by VT_WAITACTIVE may be the cause...
Tested with lightdm 1.2.0-0ubuntu2 in precise.
