I have been running Linux on a X1 based laptop for the last 12 - 18 months, as my personal laptop . This was mainly as a learning experience but I do use it for real work (code, PCB design, web stuff). Originally with the Ubuntu concept and then Arch Linux ARM. While the out of the box experience is rough (varies make / model), with some work (patching, compiling kernels, pulling firmware from exe's) the experience for me is usable. Most stuff works, no encoders, no AV1 decode, no camera or AI accelerator. If you monitor the patches going into the kernel, things are going from strength to strength (I am excited for 6.18). My real hope is that allot of the software work carries over to the X2, and better thermals, it gets hot far too easily. Aside, ARM in the workspace (including Apple) is all fun and games up until you need to build out a Windows VM image for a 20 year old delphi project.
