SteamOS for All receives new cell processing and HDR support

ChimeraOS is a custom gaming distro based on SteamOS that brings Valve's Linux operating system from the Steam Deck to everyone's desktops. In the latest version 45, ChimeraOS has received a very comprehensive makeover with a new kernel and the latest graphics suite. The modifications are primarily aimed at classic desktops, but also take into account a large number of current laptops.

ChimeraOS 45 with Linux 6.6 and Mesa 23.3 offers HDR support

The new basis for ChimeraOS 45, which like SteamOS is based on Arch Linux, is the current operating system kernel Linux 6.6.10 (“linux-chimeraos 6.6.10-chos1”), which is supported by the updated Mesa 23.3 graphics stack. 3 and one version 0.28.0-3 updated OpenGamePadUI is supported. For the first time ever, HDR support can now be found directly in the kernel, a fact that owes at least as much to the huge success of the Steam Deck OLED. the Release notes From the development team read the following on the GitHib project page:
