If you, like me, came across the issue where steam “forgets” your second/third SSD, here’s an easy way to solve it:
- Open the “Disks” app.
- Click/Select a disk having the issue.
- Click the Gear/Settings/Config icon.
- disable “User Session Default”.
- Make a folder anywhere(In my case, I did inside /home/peq42), name it something like “mounted drives”.
- Copy the folder’s address(In my case: /home/peq42/mounted drives ).
- Back on the disks app, where it says “mount point”, replace whatever is, before the final forward slash, with the address you copied before.
- Click “Ok”
- Repeat 1 through 8 for all the disks, except folder creation.
- Restart your computer
- On Steam, go to Settings > Storage
- Add those drives
The reason why steam was “forgetting” your drives was because everything mounted on /mnt/ is “temporary”, and the address name changes on restart.
I’ve done the above on Linux Mint(22.3), but should work on later versions too. Most linux distributions have a “disks” app you can use for this and follow more or less the same steps but, in case you don’t, search online “how to mount drives to a folder” and do it to the folder you make following whatever tutorial you find.
This should also fix problems with other programs having a hard time reading files/accepting drag and drop from /mnt/ mounted drives.
