According to these new numbers from Valve, the Linux customer base is up to 1.96%, or a 0.52% jump over June! That’s a huge jump with normally just moving 0.1% or so in either direction most months… It’s also near an all-time high on a percentage basis going back to the early days of Steam on Linux when it had around a 2% marketshare but at that time the Steam customer size in absolute numbers was much smaller a decade ago than it is now. So if the percentage numbers are accurate, this is likely the largest in absolute terms that the Linux gaming marketshare has ever been.

That’s so odd, maybe there is an issue with your specific distribution.
As mentioned in another comment I had the same problem over 3 wildly different distros I also never fiddle with any system files or anything
