Public bug reported: Hi, In some boots my laptop's graphic card(Intel Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx) only display a black screen, everything else seems to work, the system is able to produce sounds. Its possible to make the display go back to work after close and open the lid. After some tests and debug, it was seen that the screen wasn't entirely black the brightness seems to be setted to the minimum(almost impossible to see), and with a external monitor the brightness level was checked in `/sys/class/backlight/intel_backlight/actual_brightness` it was set to the default value, so the problem can't be the backlight. I believe is a i915 driver problem.
it was tested the following kernel's params: i915.enable_dpcd_backlight=3 i915.enable_dpcd_backlight=1 i915.enable_dpcd_backlight=0 i915.invert_brightness=1 i915.invert_brightness=-1 i915.modeset=0 i915.modeset=1 i915.register_backlight=1 Still no results.
