Last Tuesday, loads of Linux users—many running packages released as early as this year—started reporting their devices were failing to boot. Instead, they received a cryptic error message that included the phrase: “Something has gone seriously wrong.”
The cause: an update Microsoft issued as part of its monthly patch release. It was intended to close a 2-year-old vulnerability in GRUB, an open source boot loader used to start up many Linux devices. The vulnerability, with a severity rating of 8.6 out of 10, made it possible for hackers to bypass secure boot, the industry standard for ensuring that devices running Windows or other operating systems don’t load malicious firmware or software during the bootup process. CVE-2022-2601 was discovered in 2022, but for unclear reasons, Microsoft patched it only last Tuesday.

The reports indicate that multiple distributions, including Debian, Ubuntu, Linux Mint, Zorin OS, Puppy Linux, are all affected. Microsoft has yet to acknowledge the error publicly, explain how it wasn’t detected during testing, or provide technical guidance to those affected. Company representatives didn’t respond to an email seeking answers.
I thought the whole point of the Quest is that it’s a standalone device that runs games untethered?

Sadly, no, the Oculus software suite is Windows only, no exceptions. If there are a couple must-plays on your list that are Oculus Store only, you’ll have to keep Windows around. Who knows, maybe someday there will be some workaround, but that’s not the case at the moment.
The good news is, for anything that isn’t exclusive, ie on Steam or even Epic/GOG, there are options. I use a piece of software called ALVR. You install the ALVR server on your PC and the client on your Quest 2 (look into how to use Sidequest if you havent already). You launch both pieces of software, launch SteamVR on your PC, make sure the ALVR server sees it, connect the Quest client to the server, and voila, wireless PCVR on Linux. I’d say the performance is at ~85% of what you could expect on Windows natively, give or take 5 or 10% depending on your setup. By no means unplayable.
There is also OpenComposite. I know much less about this so it would be worth doing some research, but it basically bypasses SteamVR entirely. This would be especially handy for, for example, a VR game installed via Heroic Launcher (Epic, GOG, and Amazon games), where getting a game that requires SteamVR to actually see SteamVR would be a huge headache due to the separate prefixes/wine versions. There may be a way to accomplish that, but from what I can tell, OpenComposite is specifically designed to help avoid those headaches.
