Thank you eselarm for that very detailed explanation of your use case with the Rockchip SBC.
We seem to have very different needs, I am looking to replace my laptops with this OP5+ and at the same time see if ARM/RISC is the direction I want to go in. Before there was Linux/x86 there was UNIX and it almost always ran on RISC CPUs, I have been around long enough to have experienced those days.
I am looking for a stable desktop environment that can run LaTeX, Blender, LibreOffice, a handful of CAE applications and some Arduino development day in and day out, I am not looking to tinker on a new SBC every week. Once I install an OS I will keep it for a while, until I upgrade to the next release.
I have decided to settle on Joshua Riek's Ubuntu 24.04 with the 6.1.0 kernel as it meets all 3 of my requirements stated above. Unfortunately Armbian is not ready for the OP5+ quite yet and I'll check back to see if a new release with 6.13 or 6.14 will work for me, until then I will use Joshua's Ubuntu release: ubuntu-24.04-preinstalled-desktop-arm64-orangepi-5-plus.img.xz
