Off the top of my head:
- Waking from sleep with the lid closed while using an external monitor straight-up doesn’t work. Not with keyboard and mouse input, not even by hitting the power button.
- Thunderbolt hotplugging JUST started working in 22.04, and it still flakes out quite a bit. I think my laptop would normally maintain days to weeks of uptime if it weren’t for Thunderbolt-related issues.
- Battery life in-use is like three hours, max. I’ve never used anything but Linux in this machine so I don’t know how battery life stacks up in Windows, but I know that I was using a MacBook Air at work over a decade ago that did 6+ hours.
I strongly prefer to run Linux and I’ve used it as my primary desktop OS since 2001, but I can’t think of a single Linux laptop in the past 22 years that hasn’t presented me with significant problems that I had to either work around or accept.
There are also weird audio/mic UX issues. Not sure if this is the same across all platforms, but - I usually have my laptop hooked up to an external monitor, audio output set to the external monitor, and my headphones plugged into the monitor. Yesterday, I locked my desktop and stepped away from my desk with the music still playing. When I came back, music was playing out loud from the laptop speaker. That's because the monitor went to sleep, so the HDMI audio sink went away, and the OS "helpfully" switched audio output to the laptop speaker which was set to full volume.
Logically, it makes sense that would happen. Clearly, I am to blame.
