Xstartup Permission Denied | Fixed

Did you set up a VNC server and are now not sure about using it via the terminal?

Our experts are here to help.

1. To begin with, install a GUI on the Ubuntu server. This is done by connecting to the server via SSH. Then log in as root, and finally install the `ubuntu-desktop` package:

   apt-get install ubuntu-desktopCopy Code
2. Then, we have to install the GNOME Display Manager to manage our graphical sessions:

   apt-get install gdmCopy Code
3. Next, reconfigure the X server to ensure everything is set up correctly:

   dpkg-reconfigure xserver-xorgCopy Code
4. Then, start the GDM service to launch the GUI as seen here:

   /etc/init.d/gdm startCopy Code
5. Now, it is time to install the TightVNC Server. This lets us connect to our Ubuntu machine remotely:

   apt-get install tightvncserverCopy Code
6. After that, open the `~/.vnc/xstartup` file and add the following configuration:

   unset SESSION_MANAGER
   exec /etc/X11/xinit/xinitrc
   xsetroot -solid grey
   vncconfig -iconic &
   xterm -geometry 1024x768 -ls -title "$VNCDESKTOP Desktop" &
   exec gnome-session
   Copy Code
7. Then, we have to set the correct permissions for the `xstartup` and `xinitrc` files:

   chmod +x ~/.vnc/xstartup
   chmod +x /etc/X11/xinit/xinitrc
   Copy Code
8. Reboot the server to apply the changes.
9. Now, start the VNC server with the display number we want to use:

   For example:

   vncserver :2Copy Code
10. Then, we have to download the VNC Viewer and connect to our server using the address `serveraddress:5902` (590 + the display number).
11. If we want to stop the VNC server, we can use this command:

    vncserver -kill :2Copy Code

Alternative Method

Alternatively, we can link the `xstartup` file with the `xinitrc` file using the `ln -s` command and set the correct permissions to resolve any permission-related issues:

ln -s /etc/X11/xinit/xinitrc /root/.vnc/xstartup
chmod 755 /root/.vnc/xstartup
Copy Code

With these steps, we can set up a VNC server on our Ubuntu machine with a GUI for remote access.
