RGBMatrixEmulator VS OpenRGB

https://github.com/ty-porter/RGBMatrixEmulator

One of the side projects I work on is a scoreboard that displays MLB scores. It's highly configurable -- you buy the size panel you want and a Raspberry Pi, install the software, and you can configure it to display games, standings, and news headlines for your favorite team or division.

The problem is that the hardware is purchased by the end user, so it can come in many different sizes. I think we officially support 6 or 7 sizes right now, and each panel can be a chunk of change if you get a nice one. If we wanted to test on every device that means I need to shell out 50 bucks x 7 sizes, plus Raspberry Pi and wiring adapter, so not insignificant for a hobby project. Instead, I wrote a drop-in replacement emulator that makes it super simple to emulate any size panel across a variety of display types.

The most advanced display adapter spins up a minimal webserver and serves emulated images over a websocket, meaning you can display your panel over the network on pretty much any device with a web browser.

I write about it quite a bit, if further interested: https://blog.ty-porter.dev/categories.html#emulation-ref

Hi guys, I'm the developer behind RGBMatrixEmulator, a Python library to emulate LED matrices that run on Raspberry Pi via rpi-rgb-led-matrix driver library by Henner Zeller.

I maintain RGBMatrixEmulator, a Raspberry Pi LED matrix emulator written in Python. It emulates the Python bindings provided by rpi-rgb-led-matrix, the most common LED matrix driver beginners choose when writing code for LED displays.

kernel patched with cherry-picked zen patches (also used in TKG kernel on Arch https://github.com/Frogging-Family/linux-tkg/blob/master/linux-tkg-patches/6.1/0003-glitched-base.patch) kernel patched with OpenRGB (https://gitlab.com/CalcProgrammer1/OpenRGB/-/wikis/OpenRGB-Kernel-Patch) kernel patched to enable amdgpu for pre-polaris cards by default instead of radeon kernel patched with steam deck support kernel patched with microsoft surface support (https://github.com/linux-surface/linux-surface/tree/master/patches/6.1) kernel patched with asus-linux patches for better asus laptop compatibility. (https://gitlab.com/asus-linux) kernel patched with simpledrm fix/workaround for nvidia (see: https://gitlab.com/cki-project/kernel-ark/-/merge_requests/1788 ) kernel patched with ACS override IOMMU patch for better vfio iommu group control (https://aur.archlinux.org/cgit/aur.git/tree/add-acs-overrides.patch?h=linux-vfio) kernel patched with Lenovo Legion Linux support (https://github.com/johnfanv2/LenovoLegionLinux) kernel patched with customizable USB polling rate support (https://github.com/KarsMulder/Linux-Pollrate-Patch + https://github.com/GloriousEggroll/Linux-Pollrate-Patch) kernel configured with ashmem, binder, and android support for Waydroid QSG_RENDER_LOOP=”basic” set for nvidia cards — fixes nouveau Wayland freezes. The nvidia proprietary driver sets this anyway after installation. This fixes the issue of KDE Wayland often times freezing on first login before nvidia proprietary drivers are installed. latest mesa release version provided for AMD/Intel desktop/GL drivers, mesa-git vulkan drivers provided for latest vulkan fixes/updates, built and updated regularly (every few weeks to a month on average) glibc patched with clone3 disabled (fixes CEF compatibility in applications using outdated CEF such as Discord, Steam beta) glibc patched with broken commits reverted to allow EasyAntiCheat to work for Rogue Company dnf max parallel downloads increased to 6 gst-editing-services disabled — causes WINE to hang when creating new prefixes lspci symlink from /usr/sbin/lspci to /usr/bin/lspci for Dying Light: https://www.gamingonlinux.com/forum/topic/2766/post_id=17381 ‘nobara-controller-config’ package provided for easy installation of xone and xpadneo drivers and firmware. gnome variable refresh rate patches added for mutter: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1154 gnome mutter check-alive-timeout increased from 5 seconds to 30 seconds. This is the amount of time gnome waits before trying to determine if an application is not responding. At 5 seconds it almost immediately triggers for league of legends (and some other applications) if those applications are still in the loading phase. We feel 30 seconds is a much more reasonable wait time. gnome mutter patched with x11 fractional scaling: https://salsa.debian.org/gnome-team/mutter/-/raw/ubuntu/master/debian/patches/ubuntu/x11-Add-support-for-fractional-scaling-using-Randr.patch gnome mutter wayland and x11 fractional scaling enabled by default: https://wiki.archlinux.org/title/HiDPI#Fractional_scaling gnome shell patched with https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2358 to allow gnome-extension-manager to auto-update without needing gnome-extension-app installed. (They both function the same but gnome-extension-manager allows management of extensions without a browser). gamescope version regularly updated goverlay version regularly updated mangohud version regularly updated vkbasalt version regularly updated vm.max_map_count = 16777216 set by default for Star Citizen xwayland patched with fix for locked fps on some systems: https://build.opensuse.org/package/view_file/home:hwsnemo:xwayland/xwayland/xwayland-vsync.diff?expand=1 supergfxctl and gnome extension + kde plasmoid enabled for laptops. Vendor agnostic and works with any combination of intel/amd/nvidia gpus.

I have a 30 series ASUS card, and Armory Crate didn't even detect my Strix 3080. Took me awhile to remove all of their bs software from my system (big thanks to Autoruns and BCUinstaller). Now I use OpenRGB to control everything.

Have you created an issue here?

OpenRGB doesn't see my Steelseries Apex 9 keyboard - is there any way to fix this? I saw adding Apex 9 recognition was requested here and a GitLab branch that adds the Apex 9 recognition was even linked but I don't know how to add this user-submitted update to OpenRGB. Any tips?

I'd much rather we had some convergence on a common standard so we could all just use something like OpenRGB, except knowing the monkey's paw that is modern tech we'd just end up in relevant XKCD territory.

OpenRGB is my current choice, open source is always a plus.

Before upgrading myself to a Keychron Q3 i used OpenRGB to control RGB on Logitech trash hardware : https://i.imgur.com/mkzcQDU.png
