I am unable to get any output to my external monitor on 12.10. The monitor is recognized and shows the native res (1920x1080, correct) but enabling has no effect. Graphics chipset is Intel Ironlake (Arrandale).

I have tried:

Full system update after installing
Oibaf PPA updated drivers (https://launchpad.net/~oibaf/+archive/graphics-drivers)
Enabling SNA
Kubuntu 12.10 (in addition to Ubuntu 12.10) Both were fresh installs.

Nothing works, any troubleshooting ideas? Everything is fine on 11.10.

UPDATE 1: Also tried using Intel drivers from Xorg-Edgers PPA (https://launchpad.net/~xorg-edgers/+archive/ppa) Still no output on HDMI.

Looking at https://wiki.ubuntu.com/Releases 13.04 will reach EOL in January 2014, while 12.10 will reach EOL in April 2014, therefore if a 12.10 user hasn't upgraded to 13.04 and subsequently to 13.10, there will be a 3 month period where a 12.10 user has a supported version of Ubuntu, but will be… >>> More
