In the past, I had been using Ubuntu LTS releases for my main HTPC. That original install had been upgraded many times, but actually started out as an Ubuntu spin-off called Mythbuntu. Of course since Steam on Linux was first released, Ubuntu was the most well-supported distro at the time, and still technically is (Look in Steam’s .local install directory and you’ll still find ubuntu12_32, ubuntu12_64 folders which are pre-packaged dependencies & libraries for steam-runtime built against Ubuntu’s core libs for each architecture). It ran many games fine, and the added bonus of a distro focused on being an HTPC meant that I could use mythgame as a frontend for emulators, steam, or whatever else needed a launcher. Meanwhile, the main focus of MythTV was being an OSS DVR that supported TV capture cards, commercial skip, and transcoding.

It ran all those things well, except trancoding (no VAAPI, only VDPAU & not many codecs), up to a point when my original Nvidia GT240 card became deprecated by Nvidia’s binary blob drivers. Thanks to the version-pinned 340 proprietary drivers not being well supported on newer kernels, I have been forced into a hardware upgrade cycle. Decided to go with AMD this time around, but the first card has some kind of hardware issue (9 times out of 10 after a reboot, the amdgpu driver says the SMU won’t init properly… same on windows but no helpful error messages, just doesn’t work at all). The card arrived without an OEM box, and seemed suspiciously in used condition although it wasn’t sold to me as a used model. Thanks to testing in a rolling-release distro based on Arch, I was able to prove that it wasn’t due to software, but instead was a hardware issue. I’m going to send that GPU back and get another one to replace it once prices get less insane.

I tested out various Manjaro LiveCDs to check if it was a software or driver problem, and did get the GPU working about once every 10 reboots. I decided to go with a full install of Manjaro Sway edition to try and test out wayland & a more minimal window manager. I didn’t think I’d like it at first, as I’d always avoided using i3wm in the past… but actually it’s starting to grow on me and I think I’ll try this out as a daily driver for a while. After following some instructions on the Arch wiki to identify missing steam-runtime dependencies and installing them via pacman, everything works, including Proton-based games. Technically Steam is still running under Xwayland, as evidenced by xlsclients output, but it works and seems much snappier than running on Ubuntu with X11.
