[Pkg-xfce-devel] Bug#786373: lightdm switches back to tty1 after auth, manual switch back to VT7 required

[Robert Waldner]

Package: lightdm
Version: 1.10.3-3
Severity: normal

Dear Maintainer,

I have the following situation: after cold-booting lightdm comes up as
expected, I authenticate and then get a blank screen (no signal to the
monitor). I then have to manually switch to VT1, stop/start lightdm,
authenticate again and am auto-switched to VT1 again. If I then switch
to VT7, I finally get to my normal X session with Enlightenment.

   * What led up to the situation?

Switching from GDM3 to lightdm (after upgrade to Jessie).

lightdm.log after getting the no-signal blank screen:

Since this didn't happen with GDM3, I don't think (ICBW, of course) this is
a problem with Enlightenment. I also get the same behaviour on my box at
work, same setup, so I can reproduce this.

Any hints very much appreciated - this is somewhat annoying.

Kind regards,
robert
