Hello @Dainted, this reads like a duplicate of https://github.com/ValveSoftware/steam-for-linux/issues/8179. Can you check if Steam was completely closed before you tried to run it from a terminal? If steam detects that it's already running, then it'll hand off to the existing instance and exit early. It's also worth testing the workaround in that issue report.
Disabling the Steam runtime is unsupportable.
Your system information
When I launch Steam after changing my Nvidia settings from [On-Demand] to [Performance Mode], Steam refuses to open, when trying to launch using Integrated and then Dedicated from the right-click menu it will still refuse to launch.
The only output from Steam when entering
steaminto a terminal window is:steam.sh[29217]: Running Steam on ubuntu 22.04 64-bitsteam.sh[29217]: STEAM_RUNTIME is enabled automaticallysetup.sh[29355]: Steam runtime environment up-to-date!steam.sh[29217]: Steam client's requirements are satisfieddainted@Charcoal:~$When launching as Steam Native using
env STEAM_RUNTIME=0 steam, I get the following result:steam.sh[29753]: Running Steam on ubuntu 22.04 64-bitsteam.sh[29753]: STEAM_RUNTIME is disabled by the usersteam.sh[29753]: Can't find 'steam-runtime-check-requirements', continuing anywaydainted@Charcoal:~$Uninstalling Steam, deleting all files from
/home/dainted/.steam/and reinstalling only works temporarily and once steam is fully closed, it goes back to the same issue (Remember password was also disabled after reinstalling).I hope to get some support and have this issue fixed.
