Would obviously be beneficial to be generic. After failing to build my own window manager (using Python), I am currently modifying Openbox to support the original idea in this thread: changing desktops on a per monitor basis. I've been wanting this feature for so long, and since I added a third monitor to my setup, I've found it to be nearly essential. It's going to be a bit more than a post-move hookAs Mikael mentioned, this violates the EWMH spec and is essentially incompatible with all existing pagers. (I need to make one of those too.) I'm adding a new property called _NET_VISIBLE_DESKTOPS that should provide all the information an outside application (like a pager) needs. (Maybe I'll submit it to the EWMH people, but they haven't updated the spec in a long time...) The _NET_CURRENT_DESKTOP property is still relevant, I think. Ideally, this should only change behavior on multi-head setups using Xinerama. Hopefully I'll make a public branch of Openbox available soon; I plan on keeping it up to date with Dana's master branch. The only window managers I know of that exhibit this feature are Xmonad and i3; except the latter ties each desktop to a specific monitor that can't be used on other monitors. That is, only Xmonad gets this right in my opinion. > > >> >>> As an aside, what do other xinerama users do about setting background >>> images? I wanted to set two images, one for each monitor.
