So out of curiosity I tried today with the two finger scrolling, and trying to scroll a document in gedit is jumpy as in not very smooth. See though that I am currently using the package from here: http://koji.fedoraproject.org/koji/taskinfo?taskID=10152166 See https://bugs.freedesktop.org/show_bug.cgi?id=90990 for reference.

this is a semi-mt touchpad where the resolution just isn't there when two fingers are on the touchpad. I'm almost tempted to disable two-finger scrolling on those pads. have a look at the value jumps between the various ABS_MT_POSITION_X/Y coordinates, they are huge.
I wonder if it is a bug in the driver since on windows two finger scrolling is also the default way. Though I always preferred the edge one.
does the two-finger scrolling work fine in Windows?
yeah, on windows the two finger one seems to work fine. See also that for linux the driver was reverse engineered
judging by Hans' comments this should be fixed with recent kernels, any chance you can try that? looks like v4.2-rc1 has all the changes.
ping?
Peter, sorry for not replying. It seems f22 still has 4.1 so I'd rather wait for the update before messing up with the kernel.
ok, thanks. I'll close the bug for now, otherwise I keep clicking on it wondering why it's still open :) As I said in Comment 6, the patches to fix this should've gone into v4.2-rc1, so if it the problem still occurs with that kernel, please reopen this bug.
