  Laptop monitor does not initially display

Status in linux package in Ubuntu:

Bug description:
  When booting my laptop from a cold boot, my monitor is black and shows
  nothing. It's as if it's defaulting to an external monitor that isn't
  there. Hotkeys like for wireless work and hitting certain keys I can
  get alert beeps. If I close my lid after a certain time, let the
  laptop sleep, then open it back up, my laptop display works. I have to
  do this on every boot though. I tried adding 'nomodeset' to grub and
  that fixes the issue, however suspend no longer works, trying to
  suspend my laptop will always result in a crash and having to reboot
  every time.
