Re: [Linuxwacom-devel] [PATCH 0/4] xf86-input-wacom touchpad improvements for Bamboo Pen Touch
Hi, Chris. Okay, I agree that I didn't done enough investigation on the case. Now I see that I reinvent Device Accel Constant Deceleration property. So, I remove my fourth patch from the patchset. Right now I'm not interested in providing a good default value working in xf86-input-wacom, but maybe somewhen later I will. Thank you for pointing me to x.org wiki. Alexey.
