Hi :)

I'm Magnus, and I'd like to help. I'm not scared of working with
low-level stuff in C :) My experience is more with C++, so I will need
some getting used to C idioms.

I have successfully installed and run Wayland and Weston on my
machine, both on a dedicated virtual terminal and nested within X. I
am super excited about how great an improvement Wayland can turn out
to be!

I think it's most effective if I can help with something that's
specific to my hardware and scratches my own itch, so I'll proceed by
presenting my hardware and ideas for related things that may need
implementing:

I have a MacBook Pro Retina 13", late 2012 model:
http://support.apple.com/kb/sp658

My graphics chipset is Intel HD Graphics 4000. There are performance
issues here, especially with big textures (8kx8k) and as the video
memory gets exhausted, but I'm guessing the problems here are outside
of the scope of wayland. Maybe there is something to be done here to
support a resource constrained environment?

I have a high DPI display (227 PPI). I can help with stuff related to
high DPI support.

I have an external monitor, Dell 30" at 2560x1600 pixels resolution
(100 PPI). I can help with external monitor-support and dynamic DPI
support. I don't know what plans you have made for supporting a
hetrogenous DPI environment. I also like to close and tuck away my
laptop while using the external monitor. This doesn't appear to be
very well supported, save from configuring it explicitly in
weston.ini.

I also have an integrated touchpad which has very high resolution and
sensitivity. I don't know the low level details of programming this,
but I'd like to help with designing good support for this input
method. Ideas:

 * Support for (sub-)pixel resolution of two-finger scroll. In X.org,
two-finger scroll is mapped to button-events, which means that the
resolution of scrolling is reduced to line-level. Can we support such
smooth scrolling in wayland?

* Similar support for several-finger-gestures. In X.org, I use
touchegg to switch workspaces by a four-finger swipe. The interaction
is like this: 1. put four fingers on touchpad, 2. swipe left/right, 3.
let fingers go, 4. observe that the workspace changes. The
corresponding interaction in OS X is like this: 1. put three fingers
on touchpad, 2. as I swipe left or right, the workspaces on the screen
respond proportionately by moving right/left, 3. as I let go, one of
the workspaces snap to fill the screen.

The feedback in OS X is immediate, making the interaction feel much
better and leaves the user with a much greater feeling of control. Can
we support this in wayland?

I also have a Wacom Bamboo Pen&Touch, but I am not a graphics artist.
I can help with testing tablet-/pen-stuff.


That's probably more ideas than I can realize on my own :) Does
anybody want to help me with contributing something valuable in one of
these areas?


Thanks,
Magnus Hoff
