[Bug 1290832] [NEW] No console display on D2xxx/N2xxx integrated graphics with raring enablement stack
Public bug reported:
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

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
