Happens every time when using Linux 4.3.0-2. As soon as X starts over half of the screen is messed (left side of the screen). Switching to the virtual terminal doesn't help, same area is messed in text mode. Couple of workarounds: *Booting Linux 4.2.0-22-generic *Connecting external (VGA) monitor. Now both (internal+external) are working. External can be disconnected then. *From grub boot to recovery (kernel 4.3.0-2), then resume. Now screen is working, but resolution is 640x480.
