I am trying to get a remote screen on C7.
I did the following on C7 server:
yum install tigervnc-server
cp /lib/systemd/system/vncserver at .service
/etc/systemd/system/vncserver@:1.service
systemctl daemon-reload
edit /etc/systemd/system/vncserver@:1.service and replace
<USER> with myuser
su - myuser run vncpassword to set password
systemctl start vncserver@:1.service
systemctl enable vncserver@:1.service
Then when I use something like vncviewer from a windows laptop into the
linux desktop
I get the password prompt, but the next screen says "oh no, something went
wrong".
Did I do something wrong above?
Thanks,
Jerry

You could try it with a desktop manager other than Gnome3. -- Jonathan Billings <billings at negate.org>

If not, I'm suspicious that the file copy created a file with the wrong (default) SELinux context, which you could confirm with "ls -lZ", and fix with restorecon. Also you can run "ausearch --success no --interpret -ts today" to check the audit log for permissions issues that silently escape notice. Hope that helps, -- Charles Polisher

I am using the MATE desktop if that makes a difference. 2) selinux is disabled on this machine. Thanks, Jerry

Thanks Frank. The below in fact worked and restarting the service. Jerry To get mate to show up use the follow text in your ~.vnc/xstartup file: #!/bin/sh # Uncomment the following two lines for normal desktop: # unset SESSION_MANAGER unset DBUS_SESSION_BUS_ADDRESS # exec /etc/X11/xinit/xinitrc [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup [ -r HOME/.Xresources ] && xrdb HOME/.Xresources xsetroot -solid grey vncconfig -iconic & x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & mate-session &
