I remember one time I installed a lot of themes for my session and I broke something and the themes changed my icon files forever and I had to reinstall Ubuntu!!
Should I just stick to changing my wallpaper and other small tweaks? I don’t really like using vanilla Ubuntu anymore, it doesn’t feel like me. Thank you very much!!
Use what distro you like, but most distros are very easy to install (some even easier than Ubuntu I would argue). KDE Neon would be a good starting point in that regard. What exactly is hard to understand about Plasma? I have heard this sometimes now but I really don’t get it, I find it to be very easy to understand as it integrates for example theming
Kvantum?
