This is the video recording of my talk with this title, done at February 4, 2024 10:00 in the K1.105 room at FOSDEM 2024. The room can hold some 800 people but there were a few hundred seats still unoccupied. Several people I met up with later have insisted that 10 am on a Sunday is way too early for attending talks…

When I was about to start my talk, the slides would not show on the projector. Yeah, sigh. Nothing surprising maybe, but you always hope you can avoid these problems – in particular in the last moment with a huge audience waiting.

There was this separate video monitor laptop that clearly showed that my laptop would output the correct thing – in a proper resolution (1280 x 720 as per auto-negotiation), but the projector refused to play ball. The live stream could also see my output, so the problem was somehow from the video box to the projector.

Several people eventually got involved, things were rebooted multiple times, cables were yanked and replugged in again. First after I installed arandr and forced-updated the resolution of my HDMI output to 1920×1080 the projector would suddenly show my presentation. (Later on I was told that people had the same problem in this room the day before…)

That was about nine minutes of technical difficulties that is cut out from the recording. Nine minutes to test my nerves and presentation finesse as I had to adapt.
