OK, so after some time trying I can come back with the following results:
While Linux does run on the Sony Vaio Tap11, this machine is not reliable. I
had a lot of difficulties getting things to run correctly - and the (second
hand) machine ended hanging itself (battery problem seems). And as the
battery is not removable and the reset did not work...
The Microsoft Surface Pro 2, on the other hand, works better than I ever
dreamed. I have got:
- Windows 10 pro "working". I don't like the OS but it's clearly more
advanced
than Linux on the "touch" side. I keep it for some PDF editing and because
it's one of the "official" OSes at work (our IT people know nothing about
Linux so they pretend it can't work for them).
- Debian 9 with everything working except screen calibration when rotated. I
still have to work on that one. Touchscreen, active pen, suspend and
hibernate (over systemctl) working.
- To do this I had to deactivate secure boot, so I get a red "surface" screen
at boot (never mind). Debian boots from grub2 but I installed refind to have
a touch enabled boot screen and that works.
- I had problems because the Linux GUI does not let me enable palm rejection.
I found a script that does that, but the pen's xinput ID changes frequently.
I ended up writing a small tcl/tk app that lets me enable / disable the
touchscreen, so now I can annotate pdfs on the screen (unfortunately only in
landscape mode).
-Trinity work well in touch mode if you increase fonts and icons a little. Not
the most beautiful screen ever but I can live with it.
