You should use a recent version from Debian sid, for example. Do you mean the ts_read_mt() tslib samples data? You might mainly use the linear plugin with ts_calibrate, but it's actually a special case. > > The problem I am facing is that I'm on X11, stuck with an old kernel (pre > of_touchscreen.c), and a Debian installation that does not package > xf86-input-tslib.

Have you read the README.md documentation, specifically https://github.com/kergoth/tslib#use-the-filtered-result-in-your-system-ts_uinput-method ? But xf86-input-tslib can also be installed seperately. It's indeed not yet packaged for Debian, but available here: https://github.com/merge/xf86-input-tslib > > Looking around I could not find any EVIOCSABS user.

Actually I don't know how common or useful it would be to edit the real device' values with EVIOCSABS. I always went the uinput way, creating a new device, until now. I'll think about it.

Both X and Y are reported x2 at the X11 level. I have used this driver too. But it shouldn't matter at all. > > Thanks, > baruch >
