NTFS disk, am I right? Also it seems it is not mounted properly, what you show is the automount from file explorer, see post below and do that first, mount your disk properly on boot, so Steam always has access to it.
Ok, at first I whould suggest to create a extra directory for your steam-library on these ssd. You can do it in your file explorer if you want. If the whole ssd is your steam-library and still full of games from your windows installation I also suggest to create an extra dirctory and move the (game-)folders in it.
Your mountpoint is at /run/media/.... Which means points to a temporary mountet media. Which means for your that your system sees these “ssd” probably first after you have mount it.
If its so you need to “mount” your ssd before you start steam. You can do this easily by open it with your file explorer.
After than you can go back to steam to the “add library” point.
In the list there I suggest first to scroll up and click the “-” in front of “home” to make it more visible.
Now you should see the whole linux filesystem and also the folder “run”. Now click the “+” before “run” and you can scroll down to “media”. The “+” before “media” leads you further to your goal. I guess you will get the trick!
And he’ll lose his library and would have to do that again the day he starts steam without manually mounting his disk. The disk needs to be mounted on boot for a proper setup.
//EDIT: the disk needs to be EXT4 for proper compatibility without manually doing som tricks for everything to work properly. If you plan to keep a NTFS disk from Windows with your game files, this is a BAD idea, you’ve been warned.
I feel this pain, I really, really do. No offense to anyone, but Systemd mounts are so much easier and safer…for experienced and new users alike. I’ve converted my fstab mount(s) to Systemd even. But …
I honestly find the fstab method to be simpler, and you can test your mount before restarting if you’re not confident you did it right. I agree that the systemd method could be ‘safer’ for example if you remove you disk then you need to edit the fstab to not have issue on boot, but I guess you could also have proper mount option to not halt on failed mount. So all in all I think both are good.
Yes, Flatpak is not the recommend way to install applications on manjaro. Its better to use the software found in the repos which are prepared to work right with the system. Sometimes applications in flatpak format have problems to access the “host” filesystem.
Kisun is right, especially for Steam. Having the flatpak or snap version means that you do not use standard folder path, there are locks everywhere as the application would be contained in a closed environment, you’re not using the system libraries but the one provided there, video driver too if I’m not wrong (or something like that). Having the repository package is the best, alternatives like flatpak, snap, the AUR, are for cases when you can not have your program working the normal way in my opinion.
