I have been using devilspie for years to place windows on Xubuntu 12.04. On Xubuntu 14.04 the first thing I noticed is that it is not getting notifications about most windows.
I tried xprop on a few windows and discovered that it exits without any output. I'm not sure if they are in any way related. If I install and switch to the Kubuntu 14.04 desktop xprop does work.
Anyone seen this behavior or know of an existing bug (I could not find one).
I don't remember for sure if devilspie or xprop worked on Unity or Gnome desktops, when I tried them it was the wee hours of the morning. I think devillspie worked with Unity. Neither of those handle multi-monitor (two separate screens) well so I gave up on them.
