Red Hat Bugzilla – Bug 1276327
graphical login screen prompt appears on closed monitor
Last modified: 2016-07-19 15:58:32 EDT
Description of problem:
When I uses the laptop with the external monitor, the lid, i.e., built-in monitor, is closed. The boot, prompt for the encrypted disk password get shown on the external monitor, but the graphical login screen goes to the built-in monitor, and the external monitor extends the built-in monitor. Therefore, I cannot see the graphical login screen. After login, the external monitor can be used normally.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Plug in an external monitor via Display Port
2. Power on the external monitor
3. Power on the laptop and close its lid
4. Enter the password for the disk when prompted on the external monitor
The monitor shows the gdm wallpaper without login prompt.
The gdm login screen is on the external monitor.
$ lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GK208GLM [Quadro K610M] (rev a1)
# the proprietary NVIDIA driver from rpmfusion
laptop: HP ZBook 17 Mobile Workstation
external monitor: HP EliteDisplay E241i
OS installed with
https://bugzilla.redhat.com/show_bug.cgi?id=691620 (But I have one built-in monitor that is always connected, although closed)
https://bugzilla.redhat.com/show_bug.cgi?id=702760 (But I connect the external monitor directly on the Display Port)
This same h/w set-up worked as expected with Fedora 20.
At first, I attempted to work around with scripts in /etc/gdm/Init, following https://bugzilla.redhat.com/show_bug.cgi?id=691620#c22. This had no effect though. Enabling
# Uncomment the line below to turn on debugging
I see that no scripts from /etc/gdm/Init are executed by gdm.
Currently, I work around the problem with
$ cat /etc/X11/xorg.conf.d/99-nvidia-display-order.conf
# xrandr reports:
# the laptop built-in monitor as DP-3 (DFP-3)
# the external monitor conneted on DisplayPort as DP-4 (DFP-4)
# Make NVIDIA X driver provide nvidiaXineramaInfo
# reporting DFP-4 first, if enabled
Option "nvidiaXineramaInfoOrder" "DFP-4, DFP-3"
