For those who want to get a glimpse in how the machine works under the hood: The XDC2021 (“XOrg Developers conference 2021”) virtual conference has just started. The [X.Org](http://X.Org) Developers Conference (XDC) is the event for developers working on all things Open graphics (Linux kernel, Mesa, DRM, Wayland, X11, etc.). Iow. all the things that make Psychtoolbox so much better on Linux than on other operating systems. > **[X.Org Developer Conference 2021](https://indico.freedesktop.org/event/1/)** > > The X.Org Developers Conference 2020 is the event for developers working on all things Open graphics (Linux kernel, Mesa, DRM, Wayland, X11, etc.). Live streams of the main talks and main workshops are on Youtube: > **[X.Org Developer Conference 2021](https://indico.freedesktop.org/event/1/page/3-attending-xdc-2021)** > > The X.Org Developers Conference 2020 is the event for developers working on all things Open graphics (Linux kernel, Mesa, DRM, Wayland, X11, etc.).

All of it is recorded - at least the main track and workshops, so available on YouTube afterwards under the same links. All slides also on the XDC site. Not the IRC chat logs though, which represent all the hallway chatter ofc., or the virtual meeting rooms etc.
