Details

With multihead setup very often I use one screen specifically for running OS in virtualization in fullscreen mode. So just by hitting ctrl+i I can toggle between the host and guest. The problem in VirtualBox is that whenever guest is focused, the top and left borders show up and right and bottom goes offscreen. That means Awesome sees the guest client as a non-fullscreen window. In vmware everything works fine. I have attached both window xprop's, maybe someone can see something not right.
This task depends upon

Please tell me that you did a mistake when creating those files:

$ grep -i fullscreen vbox.xprop vmware.xprop
vbox.xprop:_NET_WM_STATE(ATOM) = _NET_WM_STATE_FULLSCREEN
vmware.xprop:TATE(ATOM) = _NET_WM_STATE_FULLSCREEN

The first one is correct, the second one is impossible.

Also, could you attach your rc.lua?

Huh, the beginning `_NET_WM_S` got cut.
   rc.lua (20.1 KiB)

So that happens because vbox becomes fullscreen before making it visible and vmware the other way around, so as the last touch when a client becomes visible Awesome applies default rules - focus, keys, buttons, and borders.
My proposed solution at first was to get rid of global rules and apply default setings at client_manage, which does xcb_create_window and sounds like a logical place for that. But since EWMH specifications are implemented in Lua, this will be overwritten. So the only option I could think of atm is to connect to the signal inside ewmh.lua which client_manage at the end emits and use that callback to apply the default settings. That sounds more flexible way which can act based on situation and EWMH specification. I attached a patch how it **could** look like (it fixes the issue for the moment). Any better ideas?
