Description Jeff Bastian 2018-07-20 21:03:46 UTC

Description of problem:
The gdm login screen is blank (or black) with the RHEL-7.6-20180720.2 compose. I'm testing in a kvm virtual machine with spice graphics:

virt-install \
  --name=rhel-7.6 \
  --vcpus=2 \
  --memory=2048 \
  --os-variant=rhel7 \
  --disk=format=qcow2,size=20,bus=virtio \
  --network=network=default,model=virtio \
  --graphics=spice \
  --noautoconsole \
  --location=http://download.devel.redhat.com/rel-eng/RHEL-7.6-20180720.2/compose/Workstation/x86_64/os/


I verified gdm is actually running:

[root@localhost ~]# pgrep -laf gdm
1215 /usr/sbin/gdm
1265 /usr/bin/X :0 -background none -noreset -audit 4 -verbose -logverbose 7 -core -auth /run/gdm/auth-for-gdm-6kPDf3/database -seat seat0 vt1
1422 gdm-session-worker [pam/gdm-launch-environment]
1518 /usr/libexec/gnome-session-binary --autostart /usr/share/gdm/greeter/autostart --debug
1553 dbus-launch --exit-with-session /usr/libexec/gnome-session-binary --autostart /usr/share/gdm/greeter/autostart --debug


Version-Release number of selected component (if applicable):
gdm-3.28.2-5.el7.x86_64

How reproducible:
always ?

Steps to Reproduce:
1. install RHEL-7.6-20180720.2 Workstation x86_64 in a KVM virtual machine

Actual results:
virtual machine's monitor stays blank long after boot
use virt-manager or virt-viewer to Send Key -> CTRL-ALT-F2 to get a shell

Expected results:
usual gdm login screen appears
