Sub-surfaces. Now.

Wayland sub-surfaces is a feature that has been brewing for a long long time, and finally it has made it into Wayland core in a recent commit + the Weston commit. The design for sub-surfaces started some time in December 2012, when the task was given to me at Collabora. It went through several RFCs and was finally merged into Weston in May 2013. After that there have been only small changes if any, and sub-surfaces matured (Or was forgotten? I had other things to do.) over several months. Now it is coming out in Wayland 1.4 (plan), but what is it really?

Broken connection to DiNovo bluetooth device: a solution

I have a Logitech DiNovo Mini (combined keyboard & touchpad), which at first worked just fine on my Gentoo laptop, Asus G50V, using the laptop's built-in bluetooth adapter, Bluez major version 4 (4.101-r5 today), and manual connection. Then I tried to connect the DiNovo to other devices, both without and with the USB-bluetooth-dongle that came with the DiNovo. Then I wanted it back to my laptop. There was a time when it worked only if I temporarily removed the battery from DiNovo. In the end, after several weeks if not months, it did not work anymore, at all. Blindly poking around, I now found how to fix it.

Wayland on Android snapshot release: input

It is time to announce the android-4.0.1_r1.2-b snapshot release of the Wayland on Android project at Collabora! We give you: input support in Weston and a finger-painting demo!

Collabora will have people at GUADEC demoing this on real devices, though not me personally.

Forwarding evdev devices to Android

I'm working on adding input support for Weston's Android backend, and to test a normal keyboard and a mouse, I needed a way to get those as evdev devices on Android. I don't have any Bluetooth devices here, so I started hacking up evdev forwarding from a laptop PC. I could not find much information on anyone doing this before.
