[Bug 1387711] Re: Unity doesn't respect NET_WM_ALLOWED_ACTIONS

 

In that case, I have no idea how I'm supposed to remove allowed actions using this atom.
Reading the specification makes me think that passing a list that doesn't include _NET_WM_ACTION_RESIZE should cause it to be removed from the list: 'Atoms present in the list indicate allowed actions, atoms not present in the list indicate actions that are not supported for this window. The Window Manager MUST keep this property updated to reflect the actions which are currently "active" or "sensitive" for a window.'

If the property change isn't reflected, maybe it's an xorg bug instead?
Or maybe the properties are getting (re-)initialized by the decorator
when the window is mapped?

Title:
  Unity doesn't respect NET_WM_ALLOWED_ACTIONS

Status in Unity:
  Incomplete
Status in “unity” package in Ubuntu:
  Incomplete

Bug description:
  According to http://standards.freedesktop.org/wm-spec/latest/ar01s05.html :
  Atoms present in the list indicate allowed actions, atoms not present in the list indicate actions that are not supported for this window. The Window Manager MUST keep this property updated to reflect the actions which are currently "active" or "sensitive" for a window.

  However, if I set NET_WM_ALLOWED_ACTIONS to a list not containing
  NET_WM_ACTION_RESIZE (along with the MAXIMIZE atoms), I can still
  resize/maximize the window using the mouse. Only by forcing min and
  max size in the WM normal hints can I achieve the desired behavior.
