Ah ok, thanks for the clarification. I was suspicious of FBC since it rescans the framebuffer every 15 seconds or so, but if you had EXA off, it should have been disabled (you would see messages in your log about it if it was still on for some reason).

Can you build the intel_reg_dumper tool (src/reg_dumper in the git tree) and try to get register dumps from while things are working and then after the screen blanks? If we're lucky, something will have changed and that might give us a clue. Otherwise it might just be a bad mode that the LCD rejects after awhile?

Adding Hong to the cc list since he's been looking at LCD mode programming lately.

Hong, any ideas?
