I'll need you to run sudo evemu-record against your device and attach the output here. This should tell us the type of device you have and the extent of the wobbles. Just a short recording with a single touch, held for a couple of seconds is enough. see http://www.freedesktop.org/wiki/Evemu
Created attachment 122905 [details] my touchscreen evemu-record log evemu has compiled a version of Ubuntu below. https://launchpad.net/evemu (evemu-1.0.10) It has compiled a evemu. Attach the evemu-record log. (evemu-record /dev/input/event0 > mytouch.desc) Thank you.
ouch, that is one old version of evemu, what version of ubuntu is this? in that case I'll also need the output of evemu-describe for the same device, or ideally grab evemu from git so I don't need to convert the recordings: https://cgit.freedesktop.org/evemu/
Created attachment 122908 [details] evemu(git_version) compile failed.... sorry.. i'll try continue Initially, I compiled with the git version. But I failed to compile. (evemu(git_version)_compile_fail_T_T.txt) I'll continue to try to compile git version. evemu version of ubuntu to attach a log of evemu-describe.(evemu-describe_log.txt) I'm really sorry. I'll keep trying to compile the latest version of evemu.
Created attachment 122909 [details] evemu-describe log
Created attachment 122911 [details] evemu-record(evemu-2.3.1) log I fail to compile the evemu-2.4.0. But evemu-2.3.1 version was successfully compiled. Attach a log of evemu-record (evemu-2.3.1). (More information itneyo been recorded.) Thank youn.

fwiw, this is addressed now in libinput with the commit below commit fcc9a2bf187ee0e7aacf6f2f2d691337f4d471a6 Author: Peter Hutterer <peter.hutterer@who-t.net> Date: Thu Apr 14 15:21:50 2016 +1000 evdev: always defuzz absolute touchscreens No ETA on a patch for evdev yet, sorry.

first: libinput doesn't have the min/max options, we rely on the lower levels to be correct. so you'd have to fix this up with a udev rule, similar to https://github.com/systemd/systemd/blob/master/hwdb/60-evdev.hwdb same with the swapxy or invertx/y, afaiu the kernel drivers have options exposed to fix this in the kernel already. For this patch to take effect, you'll need the fuzz value set on the kernel device. Either through the kernel driver directly, or you can fix it up with a udev hwdb entry in the form of evdev:name:.... # see the other entries for the format here EVDEV_ABS_00=:::4 EVDEV_ABS_01=:::4 EVDEV_ABS_35=:::4 EVDEV_ABS_36=:::4 this would set a fuzz of 4 for ABS_X, Y, MT_POSITION_X and Y. See the 60-evdev.hwdb file for detailed docs. That fuzz is then used to stop the pointer wobbling.
Thank you Through input_set_abs_params () function from the input driver gave the Kernel set the fuzz value. I have set the fuzz value to 10 . example) input_set_abs_params (input_dev, ABS_X, 0, MAX_12BIT, 10, 0); After a shaky touch symptoms disappeared. Thank you.
