I have a cross-platform game on a Windows partition. Ubuntu 10.04 and 10.10 do not allow executing files on a NTFS partition when automatically mounted through Nautilus. I would like to know what I need to change to make my system automatically mount NTFS ( and possibly VFAT ) partitions so that the exec bits are set, at least for my user.

I tried
gconftool-2 -t list --list-type string -s /system/storage/default_options/ntfs-3g/mount_options "[defaults, exec]"
with no luck.

Any ideas?
