How-to Setup a VNC Remote Connection to a Raspberry Pi

I don’t have a Raspberry Pi board, yet I’m using one right now remotely thanks to the VNC (Virtual Network Computing) protocol.

The Raspberry Pi I use runs the latest Debian-13-04-2012 image.

Here’s how to do to access the Raspberry Pi desktop in Windows XP. These instructions could  also be followed to connect to any remote networked Linux device with minor modifications.

  1. Connect to the Raspberry Pi via SSH
  2. Install a VNC server (e.g. tightvncserver):

    # sudo apt-get install tightvncserver

  3. Run startx in the background

    # startx &

  4. Start the VNC server (it will ask a password of your choice):

    # tightvncserver

    New ‘X’ desktop is raspberrypi:1

    Starting applications specified in /home/cnxsoft/.vnc/xstartup
    Log file is /home/cnxsoft/.vnc/raspberrypi:1.log

  5. Back to your computer. Install a VNC client such as  TightVNC for Windows. You only need to select “TightVNC Viewer” during installation.
  6. Start TightVNC Viewer (In Windows XP, Start->All Programs->TightVNC->TightVNC Viewer)
  7. Enter the Raspberry Pi IP address and display number in “TightVNC Server:” field , e.g., select your connection profile and click on Connect.

  8. It should now ask for the password you chose in step 4 and you should see LXDE desktop as shown below. The color depth of the display is 8-bit, since I chose “Low-bandwidth connection” connection profile because I access the board via Internet and to make the system more responsive.

  1. It would not work on my PI as user pi

    pi@raspberrypi:~$ startx &
    [1] 1281
    pi@raspberrypi:~$ xauth: (stdin):2: unknown command “c2d7e44cbb17978f166b1e4127

    X: user not authorized to run the X server, aborting.
    giving up.
    xinit: No such file or directory (errno 2): unable to connect to X server
    xinit: No such process (errno 3): Server error.

    [1]+ Exit 1 startx

    it works fine as root !

    pi@raspberrypi:~$ sudo startx &

    pi@raspberrypi:~$ sudo tightvncserver

    You will require a password to access your desktops.

    Would you like to enter a view-only password (y/n)? n

    New ‘X’ desktop is raspberrypi:1

    Creating default startup script /root/.vnc/xstartup
    Starting applications specified in /root/.vnc/xstartup
    Log file is /root/.vnc/raspberrypi:1.log

  2. @ MrF
    Maybe there is something to change to make it work as normal user, but I can’t remember what.
    Installing gdm may solve the issue. It will start startx automatically, and you should be able to login as user Pi and run tightvncserver

  3. Works for me. I just have to use ipv4::5901.
    If I don’t specify the “::5901” after the ip address, it won’t work.

  4. Starting applications specified in /home/pi/.vnc/xstartup
    Log file is /home/pi/.vnc/raspberrypi:4.log

    getting this message when entering the input as ‘ # tightvncserver’ and thus not getting the login and verify block .
    so what to do for this thing ??
