Hello, fairly new to Fedora and I can’t get Steam to launch, I tried the flathub, and now the one from “Fedora Linux”. I recently reinstalled Fedora after a mistake that screwed up my system. Ever since then, it has not launched once. An error pops up for the flathub version, when I try to launch it.
And for the other version, which I assume is RPMFusion, it doesnt seem to launch even when putting all of these suggestions from the research I have done.
__GL_CONSTANT_FRAME_RATE_HINT=3, DRI_PRIME=1, PrefersNonDefaultGPU=false Even disabling “Run using dedicated graphics card” did not help. I am on KDE Plasma. Here is the log for when I run it in the terminal:
steam.sh[8663]: Running Steam on fedora 42 64-bit

I have also noticed my display having trouble waking up from whenever I put the computer in sleep mode, I have to press Display Port on the monitor to get it to wake up, aswell as the display settings rounding up refresh rates, Example: 143.97 Hz, when it should be 144 Hz.
