We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
Multithreaded performance is awful. The system becomes completely unresponsive if a single process uses a lot of CPU despite another core being available. Copying a file in the background slows everything down to a crawl.
That and laptops. Will hibernation work this time? Will it wake up or do I need to forcefully restart it? Will my second monitor work after hot-plugging it? Will the battery last 2 or 6 hours this time?
