Hi Jesse As I stated in my e-mail I've already tried the drm-intel-next branch This allows KDE to start, there isn't any corruptions at first, however when KDE's compositing manager starts this is when the screen becomes corrupted. I also tried Keith's patch: [Intel-gfx] [PATCH] drm/i915: fix transition to I915_TILING_NONE but this didn't change anything either Regards Mike ------------------------------------------------------------------------------ Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
