We have a MS Flight simulator X installed on an older PC , where it was running fine, up until a few months back: after that, only splash screen will appear, but then the game will not launch.
I am using Zorin OS 16.3, Steam installed through dl.flathub.org.
When it comes to compatibility: Properties/Compatibility: Proton 5.13-6 Steam/Propereties/General/launch options: PROTON_USE_WINED3D11=1 PROTON_LOG=1 %command% -FastLaunch
Many of us have been encountering this within just the last few months. Prior to that, never had a problem with Steam.
But now, many games that used to launch have just stopped launching and several of us have started threads on it.
I recommend opening Steam App > On the menubar,s elect Help > Steam Support
Select your title and submit a help ticket describing your issue in detail, the contents of terminal output for
sudo lshw -C video
glxinfo -B
It is worth trying - though I have had no response to my submitted support tickets.
Have you done any updates on the flight simulator software recently? Some people are finding themselves locked out of their games because of new anti-cheat code that doesn't play well with Steam.
Well, I can at least rest easily knowing it´s not some botched update on our PC, but Steam problem in general.
I will do that. I don´t have a high hopes though, as they will probably reply Linux distro on an old PC is now worth their time, or something along those lines.
Nvidia dropped support for your graphics card and its last working driver (340) back in 2019.
Your issue likely is a graphics issue and you need the 340 drivers. So... You will need to add the legacy-drivers repository:
