Cinnamon 2.8.8 64-bit, Linux Mint 17.3 'Rosa'
Menu > Preferences > Display
The dialog allows to enable and disable (multiple) monitors, and position them relative to each other with drag and drop.
I don't know if this dialog is specific to Cinnamon. I think I have seen the same dialog in other desktops, such as Gnome or XFCE.
I would like to report a bug for this dialog.
Which project "owns" it and where I would find the issue queue? Thanks :)
(I was first going to post the problem itself here on stackexchange, but I realize this is a bug, and should be reported in an issue queue)
