Comment 57 for bug 1241944

mh, didn't read the whole text and also just bumping in..

laptop is a thinkpad x200t.
i work with kde/kubuntu (hold in mind, that kde get a own tablet-support too, not for auto- but for rotate at all) instead of gnome, no uniquity-stuff. now, i'm on trusty and the bug is still alive. i was able to fix it for myself, may not very proper, but works.
in the end it's exactly this coordinate-matrix-transform-stuff.. i really reconize it, cause i plug out my usb-mouse (which got same effect as trackpad).

first i was filtering out trackpad and the mouse by id with if/else (if not this id!). then it worked, after restart it doesn't the first time, but after i unplugg the mouse once and plug in again it does it proper.. cause it changed the id from 10 to 11 which wasn't transformed.

now i just commented out those lines and i'm happy!

so maybe all pointer-devices are affected and this transformstuff should just go out? is it maybe a workaround? cause a lot of people seems to have inverted-mouse-problems - maybe this is just fixed proper in newer stuff.. a option, when needed a little hidden, would be great to tell, if mouseinverting should be on or off - then it shouldn't be a problem to anyone..
i mean, this is maybe a real bugfeature at same time now... and it could really drives you to madness, when you try to fix it through xinput by yourself (needed me 3-4 hours :/)

but ey, it works, so anyway, thanks for your work, thanks to make it easily fixable by using python and keep the nice work up :)

btw: Trevor, when you could push those rotate-button-changes, i will be even more happy :)
