Although DaDesktop maintains a number of popular Linux distros, there may be an occasion when a specific distro that is not available is required. DaDesktop are happy to support this for most mainline Linux distros. Please tell us where to download the ISO file and which server you want to publish the Custom OS template. 

Important:

About Disk Partition
1. Customized template requires only one disk partition or two partitions: one EFI/Boot partition and the other system and data partition.
2. LVM partition is not supported, please do not use LVM
3. The wrong partition scheme will cause disk auto resize and other functions to fail.

Linux Template

After we download the ISO file to the server, you will be able to see it under Admin Menu->OS IMAGES->ISO FILES under your account. 

Then you can prepare the template under Admin Menu->OS IMAGES->CUSTOM OS TEMPLATES

Please follow this guide carefully, and complete all the steps as otherwise full DaDesktop operation is likely not to work.

  1. Install OS
  2. Set default username to "dadesktop"; Password to "dadesktop"
  3. Set "dadesktop" account to be Auto Login
  4. Use DaDesktop or your own brand wallpaper
  5. Install spice-vdagent, using your package manager is usually the best approach.
    •  After the correct installation, restart the machine, and you should see the two running processes, spice-vdagent and spice-vdagentd
  6. Install qemu-guest-agent, using your package manager is usually the best approach
  7. Install X11VNC, using your package manager is usually the best approach
  8. Configure X11VNC
    • make sure X11VNC installed
    • run command sudo -i to open root shell
    • run below command which allows X11VNC to auto-start on reboot
      cat > /etc/xdg/autostart/x11vnc.desktop <<EOF 
      [Desktop Entry] 
      Type=Application 
      Exec=/usr/bin/x11vnc -N -no6 -rfbportv6 -1 -allow 10.0.3.1 -nopw -shared -alwaysshared -forever -repeat -nowireframe -noscr -nocursorshape -skip_lockkeys -cursor_drag -grab_buster -deferupdate 10 -speeds 6000,5000,20 -afteraccept announce-vnc-users.sh -gone announce-vnc-users.sh 
      Hidden=false 
      X-MATE-Autostart-enabled=true 
      X-MATE-AutoRestart=true 
      Name[en_US]=X11VNC 
      Name=X11VNC 
      Comment[en_US]=Share desktop over VNC 
      Comment=Share desktop over VNC 
      EOF
      
  9. Create desktop notify script  by running below commands
    cat > /usr/local/bin/announce-vnc-users.sh </dev/null
    notify-send -a x11vnc "VNC users connected: $RFB_CLIENT_COUNT"
    EOF
    chmod +x /usr/local/bin/announce-vnc-users.sh
     
  10. Check firewall setting, make sure TCP port 5900 is open
  11. Disable sudo password ( recommended )
  12. reboot
  13. Verify success

    When connect, the URL, if changed to a new URL with token query parameter, then you are good to go. This means X11VNC is working. And the text box at the bottom left of the screen, which is used for copy/paste between your own desktop and virtual desktop should now be working.
