Bug Description
I run my laptop docked with an external DVI monitor. This configuration has worked fine until 2.6.30-18, linux saw that the lid was closed, disabled the internal 1280x800 LVDS, and ran the external DVI with the full 1280x1024 resolution.
With the upgrade to 2.6.30-19, the external DVI now gets powered off during boot, and X/gdm start into an 1280x800 framebuffer which is only displayed on the internal LVDS (which is pretty pointless with the lid being closed). I have to blindly type my password to get into my session, and use xrandr to reenable the external DVI and disable LVDS.
