This guide explains how to set the nomodeset parameter in the boot process. This is very useful for the AMT servers and will allow the server to display the screen correctly on the VNC viewer plus.

1. Install the O/S. In Debian, choose the normal installer without graphics. In Ubuntu just run through the installer like normal.

2. After completion, reboot the server as normal, but interrupt the default boot in GRUB by hitting the arrow keys.

3. Highlight the very first, top option and hit ‘e’

4. Scroll down on the editor and look for the line that starts with ‘linux’. Once found, append to the end of the line with ‘nomodeset’

5. Press F10 to boot. The server should boot and not disconnect if done correctly.

6. Login as ‘customer’ and switch to ‘root’ either by executing ‘su’ or ‘sudo su’ in Ubuntu

7. Execute

'nano /etc/default/grub'

8. Look for the line

'GRUB_CMDLINE_LINUX_DEFAULT=""' and change it to GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"

9. Press ctrl-x to save and exit

10. Execute “update-grub” and wait for it to finish.

11. Reboot the server. If done correctly, the server should boot into the O/S and should not disconnect.
