My Thinkpad X201 has never caused an issue when installing any version of Linux or, more specifically, Ubuntu.
Indeed, it has a fully functioning Arch install on it right now. I installed this last night to see whether the issues I am experiencing with Ubuntu 22.04 were replicated in another distro. I also tested a full Slackware 15 install and had no issues.
When I boot from USB and try Ubuntu, the system freezes. Totally. I can't access an alternative tty. The .iso is fine (I checked) and will boot in safe graphics mode.
I installed Ubuntu from my successful boot but the system freezes at GDM, or, on the occasions that I can log in, it quickly freezes. Total freeze.
edit
I am using Xorg and not Wayland
I was warned by the installation process that I don't have an EFI partition but I don't think I need one with my Thinkpad X201. Again, Arch and Slackware (with Lilo) work perfectly.
I don't particularly want to keep Arch (I will if I have to) and I want to stay with Ubuntu on this laptop.
Am I not seeing something?
