Bug Description

Installed Ubuntu 12.04.4 Server 64-bit on Intel D2700MUD motherboard (Atom D2700), 4GB RAM

Installation process went fine. 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

You can also see a bunch of mtrr errors/warnings with both 3.2.0 and 3.8.0. On the system with 3.2.0 I get:

Forgot to add: in the things I tried, I also did a full "apt-get update; apt-get dist-upgrade", so I was on the latest 3.8.0 kernel version.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

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.

I got access the the boxes in the data centre (there are two).

The one which was on 3.13 kernel: VGA output was fine
The one which was on 3.2 kernel: VGA output was fine
However when I upgraded the 3.2 to 3.8, the VGA output was still fine :-(

This was using a different VGA monitor than I had tried before. It's possible that the 3.8 kernel had enabled a video mode which the original monitor didn't like. That was AOC I2269V, also labelled model no 215LM00040. That monitor *should* be pretty modern, it has a "Windows 8 Compatible" sticker.

Anyway, sorry for the noise. This can be closed as I was unable to reproduce it with a different monitor.
