Steam Refuses to Launch in Linux anymore

[miaurye]

So, ever since I reinstalled my installation of Linux Mint, Steam has been broken. It used to work fine, but now all it does is open and close. I went ahead and ran it through a terminal, and here is the output.

Looks like steam didn't shutdown cleanly, scheduling immediate update check

The flatpak version runs fine, though it is limited in the sense that I can only use a single drive to store my games, and cannot make desktop entries. If anyone else has had this issue, do let me know.

I had the same problem. for whatever reason the MINT driver utitility offered the nvidia driver-BLÖB "nvidia-driver-440-server Version 440.95.01-0ubuntu0.18.04.1" as recommended. Which I selected foolishly.

Further down in the list is "nvidia-driver-440 Version 440.100-0ubuntu0.18.04.1". Do note the actually slightly higher version number and the lack of "-server". Selecting this version of the nvidia blob and rebooting solved the error message. Unsurprisngly a server version does not play well with Steam. ;-)
