The ubuntu issue making me switch with vitriol is somewhat different. I simply can't switch to another DE now under ubuntu, and I hate what ubuntu did to gnome3. Any other DE but ubuntu's simply crashes and dumps me back to login. No idea why, and oddly I can't find much about it from others. It was merely impetus to evacuate ubuntu further, but like crack I can't seem to break free.
I ran 16.04 before on my xps15. Old kernels worked ok with bumblebee, but sucked at everything else, including my dell thunderbolt/usb3 dock. I'd get random network timeouts, the usb bus would just sorta die randomly. Lovely feature, really.
Upgrading it fixed TB3, but fubar'd bumblebee/gpu interaction, and powertop just sorta said I was causing planetary doom with consumption all the time. It worked, but used power like crazy. I'd be lucky to get an hour of batter life, mostly due to the stupid intel vs. nvidia vs. bumblebee issues on it. Stable network and function vs. heat - I'll take it. I was hoping moving to arch they might have fixed some of this stupidity ubuntu could obviously never figure out.
Why do I hate 18.04? Other than above gpu issues, I upgrade to find my right click on the touchpad not working, a distinct lack of a minimize button on my windows, and various things that simply didn't work out of box I needed to find workarounds for. Upgrading out of sheer morbid curiosity to 18.10 didn't fix anything, and in fact made most worse. I just hate ubuntu now, and would really like to never deal with it again.
I need to make a decent arch linux vm image I can clone and reuse, as ubuntu is even more annoying with failed upgrades as a server. I really hate having to rebuild everything every few years, but it does keep me in practice.
