Created attachment 140651 [details] Output from lspci Hello, I have a T61 notebook with an integrated Intel graphics card. When using the 3.15 kernel the screen gets corrupted during modesetting. Reverting to 3.14 resolves the problem. Bisecting the kernel shows that the error was introduced in [1ad292b51e358c8b6e9b8966889c21f1fe705489] drm/i915: get_plane_config for i9xx v13. The internal notebook monitor is connected via LVDS and the external monitor is connected via a DVI connector on the docking station.

I think this could be as possible duplicate of bug 78681.
