[Bug 1394639] Re: lightdm fails to start with 3 connected displays but works 2 displays

 

Can't confirm for for ArchLinux (Gtk 3.14) with 2 monitors. Questions:
0. proposed branch has been updated today - is bug still here?
If "yes":
1. Greeter config
2. Is it works with one or three monitors?
3. Just to confirm - password entry do not have focus (blinking cursor) until you select "Users" combobox. Right?
4. Is it works if you first focus other UI controls (panel menu)?
5. Is it works with old version?

Add this option to greeter config and describe the results:
active-monitor=0

Title:
  lightdm fails to start with 3 connected displays but works 2 displays

Status in lightdm-gtk-greeter package in Ubuntu:
  New

Bug description:
  lightdm fails to start with 3 connected displays but works with 2
  displays.

  Once lightdm has started and displays the Greeter I can connect the third display without a hitch.
  After logging in I can enable the third display

  #!/bin/sh
  xrandr --output VGA-0 --off --output DP-6 --off --output DP-5 --off --output DP-4 --mode 3200x1800 --pos 0x0 --rotate normal --output DP-3 --scale 1.5x1.5 --mode 1920x1200 --pos 3200x0 --rotate normal --output DP-2 --scale 1.5x1.5 --mode 1920x1080 --pos 6080x0 --rotate normal --output DP-1 --off --output DP-0 --off

  When lightdm is started with all three displays connected, it will
  terminate and force the Xserver to go down as well, triggering a cycle
  of Xserver/lightdm restarts. Disconnecting the 3rd display will bring
  up lightdm immediately without a glitch.
