I don’t know why HiDPI support is still so flakey, especially so with multi-monitor setups. Sometimes apps just work, and other times the UI is comically small or oversized. The only *nix adjacent OS I’ve ever seen address this ChromeOS and MacOS.
Sleeping, hibernation, deep snoozing or whatever the term is — I can’t trust a single Linux distro to not drain a laptop battery dry while the lid is closed. I’ve tried all the tricks and there’s always a catch, usually me opening the laptop to a kernel panic, ironically with 1% battery left and the processor underclocked to Celeron speeds.
Lastly and most certainly not least, the trackpad support. “Synaptics” is a synonym for unpleasant, bumbling, and janky. Granted, Windows laptops usually don’t do much better, but these clueless drivers make large trackpads basically unusable. True palm rejection seems to remain illusive, partially fixed with like dead zones, keypress timeouts, and other bandaids. And please don’t bring up Bill Harding. He’s doing his best, but the fact is that one single person carrying this responsibility speaks volumes for how much the community values this experience.
And yes, I’m aware that these things don’t just happen. I’m just saying what’s wrong. I can only send so many pull requests before giving up and buying a MacBook.
Edit:Two more things. Distros need to pick some better branding. Names like Ubuntu, Pop_OS, Elementary… It’s impossible for regular people to understand these things. And get rid of Tux on the boot screen. A penguin with a gut is unpleasant to look at and makes the whole OS seem like a niche interest for computer nerd tropes of the 90s.
