[Mikko Rantalainen]

Should it be safe to install ligthdm package from zesty to xenial to
test if it fixes the issue? (https://packages.ubuntu.com/zesty/lightdm
version 1.22.0-0ubuntu2.1)

[Touch-packages] [Bug 997483] Re: VT_WAITACTIVE does not work well with a multiseat setup

[dino99]

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

[Touch-packages] [Bug 997483] Re: VT_WAITACTIVE does not work well with a multiseat setup

[Mikko Rantalainen]

It seems to be that the problem occurs after this:

** (lightdm:1153): WARNING **: Error using VT_WAITACTIVE 7 on /dev/tty0:
Interrupted system call

(The console number depends on luck, of course.)

I would guess that whatever code is emitting that error message is not
handling the situation correctly. In case of "Interrupted system call" I
would guess the correct way to handle the problem is to repeat the
system call. I think the code instead emits this error and proceeds
blindly forward.
