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. В Втр, 27/12/2011 в 15:05 -0600, Chris Bagwell пишет: > Hi Alexey, > > Welcome and thanks for sending in the patches.
