Hacking HY300 Pro+ Projector (720p)

Hello manufacturer. Good device. But software we want to customize. If you allow, we will buy more.

Despite being advertised as "4K 1080P", it really downscales those to 720P.

Liberate desktops from ugly fonts

Blocking unwanted fonts

X11 has been, and still is, a vital piece of technology at the core of professional Unix-like workstations since decades. It has a proven track record of supporting enterprise-grade applications with long-term protocol stability and platform compatibility. It has matured over decades.

An incompatible alternative, Wayland, is being aggressively pushed by IBM = Red Hat = Gnome = Fedora = freedesktop.org. However, it is not ready to succeed X11 as it its governance model leads to never-ending discussions and prevents even the most essential functionality from existing. Think twice before abandoning Xorg. Wayland breaks everything!

It is time that the open source community reclaims what was ours to begin with. This page lists distrib

It would be so much more valuable if the firmware would be open source for the community to modify and improve.
