Since a few weeks,
lsof /mount/pointshows lots of additional lines, all having /dev/pts/... and /dev/dri/... in the NAME column.
lsof +D /path/to/mount/pointhas the same effect.
When I try to umount a filesystem from the desktop, it shows me lots of processes that do not have open files on that filesystem. I'm pretty sure about that, because most times I only need to close one or some of them to be able to umount.
As this happens on 3 PC's, it's very unlikely that I made the same configuration mistake onn all of them.
