Details

Description: I needed to use a virtualized Archlinux Gnome session. I noticed gdm was not fully loading until I uncomment WaylandEnable=false in /etc/gdm/custom.conf file.


Additional info:
Wayland 1.12.0
GDM 3.20.1-2


Steps to reproduce: Install Archlinux with Gnome in VirtualBox.
Try to launch gdm using sudo systemctl start gdm as a simple user.

You'll get a black screen. I had to tweak /etc/gdm/custom.conf to be able to log in.
This task depends upon

I thought there was a workaround like pressing enter, typing your password, enter again.

But on log out, gdm is still broken :(

There is a screenshot of the bug. With nouveau driver for my GeForce GT210 card.

I tried to see if I can reproduce the bug with Nvidia driver. I can. A screenshot to prove it.

You can see on both screenshot that VirtualBox preview window is displaying correctly gdm... But not in the VirtualBox window. Any idea?

Found this ticket on virtualbox bug tracker : https://www.virtualbox.org/ticket/13471

I'll try to see if I can reproduce this bug with Qemu or not.

There is a "workaround" I find.

Press enter. Type your password. Press enter again. Normally Gnome will be loaded. Wait a few seconds. Log out. GDM display is correct. Why?

GDM is working ok in Qemu using virtio vga display. Looks like something is broken in VirtualBox.

I tried gnome-unstable and Gnome with wayland is loading... Ouch :(

Things are better now. I launched successfully Gnome 3.22.1 with wayland in VirtualBox 5.1.8. But I can't say if the bug it completely "dead" or not.
