Description of problem:

Connecting to a VNC session to Fedora 26 leads to a black screen (worked with F25)

Version-Release number of selected component (if applicable):

26

How reproducible:

Always


Steps to Reproduce:

Configure a vncserver@\:X.service  in /etc/systemd/system:
[code]
[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target

[Service]
Type=forking
User=charlie
Environment=XDG_SESSION_TYPE=x11

# Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=-/usr/bin/vncserver -kill %i
ExecStart=-/usr/bin/vncserver %i
PIDFile=/home/charlie/.vnc/%H%i.pid
ExecStop=-/usr/bin/vncserver -kill %i

[Install]
WantedBy=multi-user.target
[/code]

Configure .vnc/config
[code]
geometry=2880x1800
depth=32
[/code]

Connect with a vnc client (in my case vncviewer from my mac)

Actual results:

Black screen but with the pointer

Expected results:

My Shiny new Fedora 26 desktop

Additional info:

* The systemd service does not work the first time, could it be fixed too?
* Does the X11 configuration line mandatory? It could be nice to use Wayland, but the 'known bugs' page said that remote handling is at 50%.
* Is there a better way to remote connect to Fedora? I'm kind of a linux noob and do not really understand all that x11-server, Vnc, Wayland, Etc. stuff...
