Disclaimer: I am very new to Linux (1 week).
I have installed the Valve version of Steam on LMDE6. I have used Disks to automatically mount the NTFS drive I used with Windows (doesn’t hold bootloader, it is just for Steam library storage) at boot ( /media/[username]/Gaming ) and I made it the default library folder in Steam.
Running games works perfectly (actually, performance is surprisingly good), but I cannot install them due to a “disk write error”.
I looked for solutions and found this page, from which I understand that I need to change permissions to the mounting point, but when I do, using chown -R, I get a “Read-only filesystem” error for all files and folders.
I can see no options to fix this in Disks and I tried to edit fstab once, but it messed things up so badly I had to use the USB drive with the portable installer to fix things.
Seconded, only pain do you find. I even tried with an exfat drive on the side, but that had it’s own pile of headaches. Don’t try to. Perfectly fine dual booting, but just pick and choose on Linux until you’re reading to fully switch.
