intel-graphics

I'm running a copy of Ubuntu 13.10 on an i7-4771 w/ Intel HD4600 Graphics using a Dell Ultrasharp 1440p monitor via Displayport.

Up until today this configuration has been working perfectly, however the latest update appears to have broken my graphics configuration, and xorg is now refusing to go above 1280p resolution.

Running xrandr it appears the driver incorrectly thinks my monitor is plugged into the HDMI port and is detecting a max resolution of 1920x1200 instead of 2560x1440. (It's actually plugged in via Displayport).

Based on the apt history.log, the latest update was for the kernel. I'm presuming the issue is that the official Intel driver hasn't been updated to support this version?

Is there any way to resolve this, or will I need to upgrade to 14.10 to get the latest driver from Intel?
