Description Anton Anikin 2010-04-01 17:00:57 UTC

Wacom ISDv4 E3 touchscreen (that works with stylus and finger touch and represents in the system as 3 devices: Wacom ISDv4 E3 Finger, Pen and Pen Eraser) worked fine with 2.6.34-rc1 kernel, but since 2.6.34-rc2 only stylus works. When touch by finger, the cursor accidentally jumps to the left or top edges of the screen (with the (X,0) or (0,Y) coordinates of the touch point), and only sometimes reacts right in the point of touch (X,Y)

Comment 1 Anton Anikin 2010-04-01 21:31:02 UTC

I have found that the reason of this problem is the patch commit 776943fd6f104a6e8457dc95a17282e69e963666
I have reverted the changes of this patch, recompiled the kernel and the finger touch works again...
So this patch should be reverted or fixed to support the Wacom finger touch...
