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@.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

That sounds like the desktop environment (Gnome3) is failing, probably because its a compositing desktop environment and fails because it can't use GL.
You could try it with a desktop manager other than Gnome3.

Hi Jerry,
Hope that works. 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,

Two things:
1) I am not using just Gnome3... I am using the MATE desktop if that makes a difference.
2) selinux is disabled on this machine.
Thanks,

Here are my notes for getting vnc to work on Centos 7 with mate:
VNCSERVER SETUP
To start vncserver: systemctl start vncserver@1:service
to kill and restart the vnc server as a user: vncserver -kill :1 vncserver :1
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 &
Thanks Frank.
The below in fact worked and restarting the service.

Hi Jerry,
I done a lot of search in google. Than I find your post, but without success for my problem.
I have add your xstartup file. But I can't get it working with this startupfile. One problem is, that I can't find the x-terminal-emulator on my machine.
Which package must I install for x-terminal-emulator in CentOS7 ?
Maybe you can have a look at my logfile and my configuration for additional hints.
I am happy for any kind of feedback.

Do you mean 'xterm' (executable in package with the same name).
The symlink called 'x-terminal-emulator' is a debianism.

Hi Jonathan,
it works with the xterm option. Many Thanks!
