I'm trying to install steam games onto my Data partition (NTFS formatted since I use that partition as a bridge for the few times I have to use windows).

I do not want it in my home folder since it is starting to get a bit full (I only have 16 gb of space left)

I tried this solution but apparently that doesn't work anymore.

I tried setting the library folder on the Data partition but I just get the response: "New Steam library folder must be on a filesystem mounted with execute permissions."

I usually mount my Data partition using the launcher mount option unity brings with it (just click on the drive on the side bar). I don't really want to change that.

So how can I mount my drives with executive permissions using the launcher icons??
