Boot laptop, when the boot process finishes I get a white screen until I hit a mouse button, after that the normal login screen appears and I can login as normal.

Also having the problem, in 64-bit 15.04 Beta 1. Haven't tried logging out though.

I haven't been able to reproduce this on Ubuntu MATE, but I just updated my Arch Linux box and got lightdm-gtk-greeter 2.0.0 and experienced the same "white" screen. Clicking anywhere made the screen repaint.

Bugs and wiki from Arch Linux.

  * https://wiki.archlinux.org/index.php/LightDM#White_screen_after_upgrading_the_GTK_greeter_to_2.0.0

Question, does everyone use multiple monitors who has experienced this issue? I do.

[Martin Wimpress  (flexiondotorg)]

The 2.0.0 greeter may display only a white screen with specific configurations. Clicking the white screen may get rid of it. A fix is pending for the next release, in the meantime you can set active-monitor=0 (or the appropriate number) in /etc/lightdm/lightdm-gtk-greeter.conf.

Reproduced on my dual screen workstation running Ubuntu MATE 15.04.

[Nils Fenner (nilsfenner)]

Having this issue as well. Running Lubuntu 15.04 with custom LXQt installation - two screens. Seems like this behaviour is caused by lightdm.

[Jakub Liput (kliput)]

The same issue in Xubuntu 15.04 - using two screens. Will this fix be available for lightdm-gtk-greeter for 15.04 as well?

Same issue in Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=785055

2 monitors, white screen, 100% CPU usage.

This seems to be the same bug as bug #1410406 (though this one says that the screen is black).

[Mohammad Anwar Shah (mohammadanwarshah)]

Where is the fix. I still experience it in 16.04. Using 2.0.1* version.

2 monitors, black screen, 100% CPU Usage.
