Phew, relatable. I get this kind of well-rooted feeling with my Linuxes all the time.
Just this year I moved my T420 from a phenomenal Xubuntu 18.04 install that was _just_ great, to PCLOS. I'm happy with the result after a lot of work, but I know there are still a ton of things that aren't what they should be.
Hundreds of keyboard shortcuts yet to migrate, hundreds of little add-ons skipped, like "did I grab whatever the equivalent of gimp-addons is, since I couldn't use apt-clone", hundreds of little scripts un-integrated from my desktop, including genmon scripts that do valuable things, which don't even have an equivalent for porting to KDE.
Before that it was...Ubuntu Netbook Edition (UNE). Tiny screen but wow it worked amazingly well on my Linux-reseller MSI Wind Netbook. I could hardly bear the upgrades away from that, to different distros, since everything worked super well.
It's hard to feel torn between such UserLand concerns (my stuff is how I like it!) and regular ol' userland concerns (my software does what I need, with the following somewhat clever workarounds).
> Exactly why even very light-weight Linux versions like Lubuntu feels slow on my computers I do not know. Maybe they lack the drivers for hardware optimization compared to Windows.
I remember this EXACT feeling coming from Windows XP, lol. I never did figure out what the difference was, but it definitely went away for me starting around Windows 8 IIRC. Today I can't discern a difference except that occasionally it seems like Linux is faster by default.
It also felt incredibly unjust back then, to a lot of us happy Creative Labs users, to migrate to Linux and learn that our slick cards & low latency didn't work that way anymore, or at all.
Fun read! Thanks for sharing it.
