Fedora 25 Tigervnc displays Black screen

Question

The system is Fedora 25. The issue is vncviewer is displaying a black screen. By comparison the vnc package list is the same as those in a Fedora 24 system where vnc viewer is displaying correctly.The same client system is used to access the server.

Other threads with this issue have been reviewed and tried, specifically vnc package requirements, $HOME//.vnc/xstartup permissions, and suggestions for the xstartup script.

Below is the xstartup script:

#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec gnome-session 
# --session=gnome-fallback
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic & 
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
startx &

Below is the output from systemctl status vncserver:

There were several threads a few years back. Those have been reviewed and tried. They do not seem applicable to this situation.

Answer 1

You can find an answer here: https://www.server-world.info/en/note?os=Fedora_25&p=desktop&f=6 - on my case the replacement at /home/USER/.vnc/xstartup

...
# end line: comment out and add like follows
#exec /etc/X11/xinit/xinitrc
#exec /usr/bin/mate-session
exec /usr/bin/gnome-session

so I used gnome-session instead of mate-session as I am using gnome-desktop. No more blank screen (wait some time until transmitted).
