Intermediate update: the machine boots with the linux- image-3.14.0-031400rc6-generic kernel, it still reports EDID errors, dmesg info below.
Unfortunately the machine is now in data centre so I can't tell if it is generating a VGA output or not! I'll update this when I'm next able to get a console on it.

But after rebooting, after the grub screen the display was completely blank. This is using a VGA connection to an external monitor (the board also has a DVI output which I have not tried). The machine was however running fine, e.g. I was able to ssh to it after I had worked out what IP address it had picked up. Attempts to resolve the problem: * Add "nomodeset" to kernel command line (both with ctrl-e and in /etc/defaults/grub). No change. * Uncomment GRUB_GFXMODE=640x480 in /etc/defaults/grub. This made the GRUB menu text appear larger, but still completely blank after that point. * Upgrade BIOS to latest version 0076 (it was on 0067). No change. The only way I have been able to get the console to work is to remove the enablement stack and go to 3.2.0-60 kernel # apt-get remove --purge linux-generic-lts-raring linux-headers-generic-lts-raring linux-image-generic-lts-raring # apt-get install linux-generic linux-headers-generic linux-image linux-image-generic linux-libc-dev linux-tools # dpkg-query -l | grep -i '3\.8\.0' # then remove these packages too Note: this is not an X11 issue - this is a server install and I don't have X11 at all. Additional info: when booting the 3.8.0 kernel I got a bunch of messages in dmesg about drm and EDID. These do not appear at all when booting with the 3.2.0 kernel ...
