SP4 i5 experience

[mkassner]

I m running the pre-build Kernel found the the g-drive.

I found two issues:

• Touchscreen is not working (neither single, nor multitouch or Pen)
• the SP4 type cover can not be removed and re-attached. It only works when its connected on boot and stays connected.

I have tested this Mint Live CD and here the touchscreen does not work wither but the typecover is hot-pluggable.

Everything else (I have not tested suspend) works perfectly so far. Fantastic Job!

Any Ideas on the two issues mentioned above?

SP4 with kernel 4.2 and 4.3, the issues you mentioned I do have, and bluetooth can find my TVbox but not pen. Side buttons not working. Close typecover lead to a system halt. Camera not working. Hot plugging of typecover is supported on kernel 4.3, ubuntu 15.10 where I used the script build_linux.sh. Suspend can't waken in kernel 4.3, either.(rather than the bug of win10: can't light the screen after suspend but system is awake)

Try the newest kernel 4.4 is a good ideal? @mkassner @neoreeps

My devices recognized are exact the same, even I tried others patches.
