Help in setting up LXDE or XFCE on CentOS 7 coupled with tiger-vnc

Question

Hello everyone,

I’m struggling in setting up a desktop environment on CentOS 7. I have tried following multiple guides but with no luck.

I have followed these guides with no luck.

I have followed a guide for LXDE with no luck either.

At some point I got it working through DO remote console following a guide for Gnome 3 for CentOS 7 but the whole desktop environment was about 2 GB on disk.

Any way I haven’t managed to have tiger-vnc working.

I tried to set it up at every attempt (7-8 times) and I managed to connect for a short time when I had installed Gnome 3. But after a reboot it failed to start hence I was not able to connect.

Is there anyone able to suggest a guide to get a light desktop environment for CentOS 7 as well as one for having constantly working a VNC server?

Thank you.

To use XFCE do yum groupinstall "X Windows System" -y yum groupinstall "Xfce4" -y and apply Step 3, 4, 5 and 6 this tutorialhttps://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-remote-access-for-the-gnome-desktop-on-centos-7 after that if you want to keep security apply the firewall and selinux settings. here is the tricky part. before you run systemctl start vncserver@:4.service edit /etc/X11/xinit/Xclients file and add if [ -x /bin/xfce4-terminal ] ; then exec /bin/xfce4-terminal fi before last curly brackets. you can start VNC server with systemctl start vncserver@:4.service I think xfce will show up in your vnc client.

The instructions below are not terribly detailed, but should get you moving in the right direction. ################################################# ## These first several can be run directly as root ## or via SUDO ## Make sure all of the packages are up to date sudo yum -y update ## This provides extra packages not included in the base sudo yum -y install epel-release ## This is optional, but is a sanity-saver sudo yum -y install bash-completion ## This installs the XFCE desktop environment sudo yum -y groups install Xfce ## This installs your VNC Server sudo yum -y install tigervnc-server ## This puts the VNC server under management by systemd sudo cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service ################################################# ## This next one should be run from the user as ## whom you will log-in using VNC. This should ## NOT be root ## ## If the user is not able to issue commands as ## root using SUDO, you will need to manually edit ## the file /etc/systemd/system/vncserver@:1.service ## as root and put in that user's name instead ## This puts the VNC user's information into the startup file sudo sed -i -e 's![<]USER[>]!'"${LOGNAME}"'!g' /etc/systemd/system/vncserver@:1.service ################################################# ## This next one should be run from the user as ## whom you will log-in using VNC. This should ## NOT be root ## ## Set the VNC password and configuration for VNC user vncserver ################################################# ## These next ones can be run directly as root ## or via SUDO ## Make sure VNC Server starts at boot time sudo systemctl enable vncserver@:1.service ## Make sure systemd has picked up the new configs sudo systemctl daemon-reload ################################################# ## This next one is only needed if you are running ## FirewallD ## Allow VNC Server traffic through the firewall #sudo firewall-cmd --permanent --zone=public --add-service vnc-server At this point, you should be able to access your server via VNC (the connection address would be the server’s IP, followed by a “:1”, so if your server’s IP address were 10.253.126.17, the connection address would be “10.253.126.17:1 ”). Note, you will likely need to configure XFCE to do anything useful, like start a window-manager (xfwm4) and a terminal (xterm) when you log in, but that’s another story, for another time (and you can probably figure it out from http://docs.xfce.org/ )
