Hi,
On my Zorin OS core 16, Steam was working fine and now it tries to launch (steam launch video) and then just crashes. (Maybe it is caused by the issue I just had with the Nvidia driver I tried to install ( Oh no! something has gone wrong after installing nvidia-34 driver - #2 by nonobio ), I don't know).
What should I do? Is it possible to repair Steam or something like that?
Thanks 
Are you using wayland or X11? How did you install steam .deb or flatpak. Did you revert back to Open Source driver for your card?
In the About screen, I can see X11.
I installed Steam following this guide: Play Games - Zorin Help (so it was the "Steam installer" in the Software app).
I think the Open Source driver is back, isn't it? I just did:
- Esc on boot: grub menu
- Advanced options
- Enable networking
- apt-get update && sudo apt-get dist-upgrade
- apt-get clean && sudo apt-get autoremove
- apt-get remove nvidia-340
- Reboot
then I checked in Software and updates: additional drivers: I can see "an alternative driver is used", like before:
Thanks
Okay, so you you installed the flatpak version of Steam, let's try the .deb instead.
First uninstall flatpak version of Steam
flatpak uninstall com.valvesoftware.Steam
Then install the .deb
sudo apt install steam
If Steam continue to crash, start Steam via the terminal and let's look at the output.
steamWill I loose my installed games?
Yes, as flatpak is an entire different system. So backup/clouding save games first.
But first let's see what this says;
com.valvesoftware.SteamThin. Is it not recommended to install Steam Installer, Flatpak therefore, despite what the Zorin guide says?
I type this on the terminal?
The problem with flatpak is it have difficulties to see outside itself as it runs in sandbox, also it uses more resources to run.
yes. type
com.valvesoftware.Steam
in terminal
Ok, so I should not use it because I have a very low ressources PC.
Is this the same for all Flatpak applications? (difficulties to see outside itself and uses more resources to run?)
It says command not found
Sorry, typos I forgot to add
flatpak run com.valvesoftware.Steam
May be a good idea. This go also for other flatpak or snap apps.
Says "not installed"
Exactly:
error: app/com.valvesoftware.steam/x86_64/master not installed
If I'm right, when I installed "Steam installer" following the guide, I checked this, and there wasn't source choice.
Is it installed at all?
flatpak listI just checked in Software app:
For Steam installer, there isn't source choice (it is how I installed Steam):
and for Steam, it is listed as installed, and the source is Zorin:
I think it is, yes:
