LightDM - Sep 2017 - LightDM crashes when switching from another X session

Hi,

I'm not subscribed, so please make sure to address me directly.

I'm running latest Arch Linux. I do the following steps to reproduce the
problem.

 1. Switch to tty2
 2. login, run |startx|
 3. Switch tty7

Then I'm kicked out of my Cinnamon session back to the login manager
(LightDM). If I close |startx| before switching back, then I'm not
kicked. Sometimes I'm kicked after the 2nd or 3rd time I switch back to
tty7. This happens only with X started. If I use another tty as an
intermediary to land on, the problem is not present.

Here's the output of `journalctl -b 0` and contents Xorg.0.log:

Do you have any ideas why it happens? Should I report it in some
bugzilla? (I didn't find a LightDM component on bugs.freedesktop.org

Regards,
Marcin

Hi Marcin,

Is it LightDM crashing? Have you had a look at the contents of
/var/log/lightdm/lightdm.log?
