Hi,
We've been seeing a lot of issues with ELAN touch screens caused by
the patch "Input: elants_i2c - Report resolution information for touch
major". It turns out that the resolution of 1 unit per mm was not
correct for a number of touch screens, causing touch sizes to be
reported as way too large (e.g. in https://crbug.com/1085648). We've
reverted that patch in our Kernel branches, but request that it be
reverted upstream as well until ELAN can figure out a more accurate
way to report the touch major resolution.
Thanks,
Harry Cutts
