From May 29 to May 31, 2026, the Linux Display Next Hackfest convened in the vibrant city of Nice, France, just after Embedded Recipes 2026. This time the event was hosted by Collabora. This annual gathering has established itself as a cornerstone event for the Linux Graphics community, bringing together a dynamic mix of kernel developers, compositor maintainers and hardware vendor to push the boundaries of Linux Graphics innovation.
For the third consecutive year, Bootlin was proud to participate, this time with a team of three: Köry Maincent, Luca Ceresoli, and Louis Chauvet. Our involvement in this event is more than just attendance, that’s a way to build a bridge between our customers needs and the Linux community.
This year’s Hackfest was particularly rich in discussions, covering a broad spectrum of topics such as MST bandwidth allocation, Native DisplayID, tiled monitors, color operations, Variable Refresh Rate, and High Dynamic Range. We presented four critical areas for which we aim at bringing improved upstream support, to meet the needs of our customers:
- Link training and firmware update issues on DisplayPort
- DRM bridge hotplug support
- Backlight configuration
- DisplayPort status properties
