Moving the mouse handling code into a separate thread

(In a puny attempt to write my SoC project progress to my mentor, I decided to expand it and share my thoughts with you) Today, we have two methods to register the pointer devices on Xorg server: (1) under SIGIO and (2) put they fd on EnableDevices set. There is also the silken mouse concept, which means updates fired during sigio handler (in the case of hw cursor). We always try to prioritize silken - i.

multiseat input hotplug

This week I spent a good time trying to understand the new input hotplug of devices on X and liked a lot. With this new subsystem the multiseat’s life will becomes easier. I’ll briefly explain here to you. Before the hotplug sweetness, to add a new mouse/keyboad on X was only possibly on initialization time. Both of Xorg drivers, “evdev” and “mouse”, made a hack to try initializations “on the run”.

Google Summer of Code 2007

Certainly, my great new is that I was accepted as a student of X.Org Foundation sponsored by Google, on Summer of Code 2007. The project’s name is Moving the mouse handling code into a separate thread and in this link you can see what does this mean specifically. Possibly, for some time this blog will be filled with a lot of posts regarding this subject :D :D :D


Here is the presentation I’ve given on 8th International Free Software Forum, at Porto Alegre. My first (really) public talk was really cool and I’ll show to you the video/photos when the organizers get it done.

Strangely, it really give me a good perspective and motivation to keep the work :) – cut here –
