Hi, I've just found a regression. The backlight adjustment doesn't work on my ivybridge mobile laptop (Lenovo X230) after the dri update. I've added debugging. It's making it all the way to the pch backlight panel update routine in intel_panel.c, but it's not changing the backlight appearance itself. The "intel_backlight" program from intel-gpu-tools" also no longer changes the backlight value. I'm going to finish rebuilding -HEAD on the sandy bridge laptop here and try it out. Thanks, -adrian
