Honest answer from someone who's used Linux as a daily driver for years:
Actually annoying:
- Fractional scaling on mixed DPI monitors is still painful (getting better with Wayland but not there yet)
- Bluetooth audio can be flaky, especially with multi-device switching
- Some professional software simply doesn't exist (looking at you, Lightroom/Premiere)
Annoying but solvable:
- Printer setup — CUPS works great once configured, but that first setup can be rough
- Gaming anti-cheat — some competitive games flat-out refuse to work
Not actually problems, just different:
- The "too many choices" complaint — you pick one distro and move on, same as picking iOS vs Android
- The terminal — you can absolutely avoid it in 2026, but it's genuinely faster once you learn the basics
