Uninstall and reinstall the GUI using yum removeВ / yum group remove and yum groupinstall again.

Be sure to watch out for any issue during the install phase that could prevent them from installing/updating properly.

Perform a yum update to install the newest versions of TigerVNC and the GUI itself.The best things you can try to fix such odd behaviour are:

Black screen with mouse -> YUM update or GUI reinstall: if you see a black screen with the mouse pointer working, that probably means that your VNC connection is working fine but there is something that prevents Desktop Environment GUI from starting properly.

Connection issues -> Firewall configuration: if you see pop-up errors saying that the client cannot connect to the remote host, you need to check your network & firewall configuration to be sure that there arenвЂ™t blocking issues that could prevent the client from connecting to server port TCP 5901.

In case your client is unable to establish a working VNC connection, you need to checkup the following: Just remember to specify the port TCP 5901 (if youвЂ™ve followed our guide). Now that everything has been setup properly, we can try to connect to our VNC service using a VNC client such as TightVNC, UltraVNC, RealVNC and so on and see what happens. The first thing to do is to install the tigervnc-server software package by opening a terminal session and issuing the following command with root privileges: Now that we know what are we talking about, letвЂ™s see how we can setup and configure TigerVNC under our CentOS environment. ThatвЂ™s why weвЂ™re chosing TigerVNC, which works exactly like that byВ starting parallel sessions of the machine desktop environment ( Gnome, KDE or other GUI)В on the connecting client VNC desktop: this basically means that a standalone virtual desktop will be created for each separate connection вЂ“ which is precisely what we want. The software was originally developed by the Olivetti & Oracle Research Labin Cambridge, UK as an open-sourceВ initiative and its source code is still available, as of today, under the GNU General Public License.Дepending on the VNC server software, the client will connect to the currently active runtime desktop (such as some вЂњmodernвЂќ softwares like TeamviewerВ or AnyDesk) or to a stand-alone virtual desktop, just like the Windows Remote Desktop RDP protocol: the latter behaviour is arguably more powerful and secure, especially if we need to control a server machine, because each session will be a unique environment configured with the permissions and grants of the connected user. The acronym VNC stands for Virtual Network ComputingВ and is a server-client protocol that allows a client machine (running a VNC client) to connect to and control a remote computer (powered by a VNC server). More specifically, weвЂ™ll do that using the tigervnc-serverВ software, a free tool that allows to do just that.Д«efore proceeding, letвЂ™s briefly recap what VNC is about.

In this post weвЂ™ll see how to setup and configure a VNC ServerВ on a Linux CentOS 7.x server machine to allow remote connections from any VNC client вЂ“ such as TightVNC, RealVNC and the likes.
