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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1290832 Title: No console display on D2xxx/N2xxx integrated graphics with raring enablement stack Status in “linux” package in Ubuntu: Incomplete 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 ...
