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.
