I've had ubuntu on my mac retina for a while now. Initially I installed it back in a 12.x release which came with quite sophisticated touch support. It had 2 and 3 button gestures, however these were unintuative for me and I followed this guide:
This enabled me to come up with some kind of hybrid between a mac and ubuntu which I was happy with. FYI - I've been using linux for far longer than a mac, but I find mac's touch support to be excellent and wanted something more similar.
At some point my mac had dead pixels and I exchanged for a new one. For time reasons I didn't repeat the above step....
Additionally I was locked out of ubuntu for a while after a somewhat annoying Mavericks update... I've just come back updated to 13.10 and the touchpad experience is terrible and I'm not able to fix:
I can't right click anywhere...
Things seem sensitive, I find myself making errors which I can't always pinpoint that seem to relate to the touch doing things sporadically.
The only gesture I can really use is two finger scrolling.
The guide I was following fails on recompile telling me that it can't find GLX, I use my machine for 3D graphics and know this is working elsewhere.
I feel like touch support should be pretty good by now with the push in to mobile in 14.x. Am I missing something?
