Hello,

This is my first post here so please do point me to other places if
this is not the mailing list to follow. I've tried IRC #debian and
#linux which pointed to ask here. So here I am.

I'm trying to make an aigo-like machine (frenchy thing: an SFR M! PC
Pocket) live "again"[1] (do not belive the posting dates, I've
migrated this "blog" in 2016 and didn't consider relevent to update
the postings to the original ones ; these are more like in the 2012
ones).

Although I've got a lot of questions, my first one is on the gma500
linux device driver. I'd like to make the touchscreen be recognized.

Is this anything doable[2] in the current state of the kernel? I'm
using 4.9.0-4-686-pae, but can switch to any other brach if prefered,
like linux-4.14-rc4.

TIH,
