One week into upgrading my 5th gen X1 Carbon from @ubuntu 18.04 to 20.04 and it’s darn near flawless! Thank you so much to everyone involved. I was delighted when I was able to wipe Windows 10 from this machine and I’ve never looked back.
I’ve just discovered KDE Connect. Combined with GSConnect for Gnome, it enables remote control of my phone from my Linux laptop and vice versa, and replaces Pushbullet for me. Very nice work!
