Submission deadline
Registration & Call for Proposals are open for XDC 2026! The deadline for submissions Friday, July 3, 2026.
The 2026 X.Org Developers Conference (XDC) is the annual technical meeting for X Window System and Free Desktop developers. Attendees gather to discuss outstanding technical issues related to the Open-Source Graphics stack (Linux kernel, Mesa, DRM, Wayland, X11, etc.) and its software ecosystem. The event is free to attend and open to the general public.
As usual, there is a defined 'hallway track' which is for time not spent in a formal presentation setting, but instead speaking in the hallway, or getting coffee. Spurring productive hallway conversations is a key goal for this conference.
The X.Org Program Committee is requesting proposals for talks, workshops and demos at XDC 2025. While any serious proposal will be gratefully considered, topics of interest to X.Org, freedesktop.org developers are encouraged. The program focus is on new development, ongoing challenges and anything else that will spark discussions among attendees in the hallway track. Additionally, while proposals for pre-recorded or virtual presentations can be submitted, as of writing, we have a strong preference for in-person talks. We are specifically looking for the following:
-
Talk (full slot) - OPEN
Technical presentation in a main conference track, with around 35 minutes of presentation plus 10 minutes of Q&A. This can be anything: a talk about work-in-progress, a proposal for change, analysis of trends, etc. -
Talk (half slot) - OPEN
Technical presentation in a main conference track, with around 15 minutes of presentation and 5 minutes of Q&A. This can be anything: a talk about work-in-progress, a proposal for change, analysis of trends, etc. -
Demo (10 minutes) - OPEN
We will try to schedule them early and have a demo place throughout the conference. -
Lightning Talk (5 minutes) - OPEN
Scheduled throughout the conference in the main track. Any hallway track discussions summaries have priority. -
Workshop, Meeting or Hacking Session - OPEN
Discussion topic for a smaller group. Ideally, two people submit a proposal, one to lead the discussion and make sure it stays on track, a second person to keep notes. Please mention relevant talk submissions for the main track that should kick off the discussion. These talks will be scheduled early in the conference program. A summary of the discussion will be presented at the end of the conference in a lightning talk.
Full/Half talk slots presenters for XDC 2026 will be selected from those who submit before the deadline: Friday, July 3, 2026. There is usually time left for late talk proposals, but do not count on it. Please do submit your proposal in a timely fashion. You can submit Workshop, Demo and Lightning Talk proposals any time, even during the conference.
X.Org has generous travel sponsoring funds with the goal of allowing anyone with an interest in attending this conference to do so. Any program proposal will be considered for a grant, please include your request in your submission. Grants are approved independently of program acceptance.
Note: You will need to log in, or create an account, to submit a proposal.
