Heres my biggest complaints so far:

it takes like 45 seconds for my OS to wake from sleep

sometimes my login screen is on my left monitor, sometimes on my right, sometimes on both!

It took me 3 hours to get wallpaper engine running

My package manager keeps telling me I am missing dependencies that I have verified exist.

video games dont perform as well on Linux as they do on windows (even baby games like Risk of Rain Returns which should run on pretty much anything perfectly)

half the time I reboot my computer I get some weird nvidia error, other times I dont at all. Generally when I reboot my computer it just stalls for like 45 seconds before actually rebooting.

it was very unclear what I needed to install to get the latest nvidia drivers installed. Got it working after a few hours of trial and error.

theres some more complaints but those are the ones off the top of my head.

oh also applying themes seems very broken. Every time I apply a theme it grabs icons from a completely different theme. For instance I applied a theme called dracula, didnt like it so I switched back to the opensuse default theme, after a while I found a different theme and applied it but suddenly all of my icons were dracula theme again... also its very hit or miss whether all of the theme actually applies.

Steam market share is honestly probably a decent metric for adoption rate of Linux as a whole.

id like to think this is because I alone decided to install opensuse (its been an awful experience)
