I havent had issues with Kubuntu honestly, but that's for my needs. The only thing that's gotten awful is the Nvidia driver I'm being offered up breaks my distro. I am never buying Nvidia after all the issues with them, I'm hoping AMD can push forward superrior graphics drivers for Linux, but I have had more issues with Nvidia on any OS I use (including Windows) than I ever had with AMD / ATI (only with Linux, or overclocked till it died).
I'm kind of excited about trying out Ubuntu Budgie though, it looks pretty smooth.
I switched to budgie but got bitten by Nvidia bug which prevented Ubuntu loading. None of the solutions I tried from forums worked so I threw in the towel. I haven’t touched my home computer in a few months but when I do I’ll be going to fedora.
Did you check if the "nouveau" OSS Nvidia driver was still installed? Happened to me all the time, so I got used to always checking and removing it manually before letting him reboot.
