The investigation was not easy…
Here is my way to proceed…
On a selection site, I checked off the essential features I was looking for.
The list gave me the choice of HP EliteBook computers and Lenovo ThinkPad X1 Yoga.
So I looked for the best matches with the long list you offer, but never found an exact match.
This method allowed me to find, in your long list, the few computers that would be the most similar to what I’m looking for: they are the “ThinkPad X1 Yoga”:
Lenovo ThinkPad X1 Yoga (20FRS2BP00) i7-6600U Skylake Integrated Graphics (HD 520)
Lenovo ThinkPad X1 Yoga (20JES15D01) i5-7300U Kaby Lake Integrated Graphics (HD 620)
I see that the other “Lenovo ThinkPad X1 Yoga” had problems.
The problem is that the 2 computers above only have 8GB of RAM, and they are no longer available commercially (in Europe).
In one of your comments above, it seems to say that Linux can’t support a graphic display? That’s weird since the ThinkPad X1 Yoga are touchscreens.
I did a second investigation: I turned to the community-recommended list, and selected the following 3 computers:
ThinkPad X1 Carbon Gen 5 (unavailable in Europe)
ThinkPad T480 (unavailable in Europe)
ThinkPad T480s (in the big list) (unavailable in Europe)
When I say “unavailable in Europe”, it means that if I want to find a computer of this kind, I’ll have to dig around, and maybe settle for a used one.
If I choose a Lenovo ThinkPad X1 Yoga roughly similar to the one on your list, I’ll easily buy a computer that suits me well and is new … however, I’d have to be pretty sure that I can install Qubes-OS without any problem.
If this is not certain, I will have to search for an (old) ThinkPad T480 or T480s.
What do you think about it?
