I just recently had a really weird bug with Linux and external USB-C display. Basically after reboot with lid closed, system was gone into madness, like display flickers, laptop blinks with its led and eventually it just dies (probably kernel panic). Turned out it's a dance between systemd putting system to sleep because external display is not connected and waking up because external display is connected. I might be wrong about it, but basically display takes some time to initialize and without input it'll turn off, so those events couldn't alight. What's worse it worked sometimes, so I spent some time distro-hopping, because I thought it's a bug in kernel or mesa. In the end I just disabled sleep mode in systemd. I don't like this solution, but it's Linux, what could I say... At least I was able to disable it, LoL. Probably with Mac I would have to live with it.
