I've also tried floating `gnome-terminal`, just for testing with for_window [class="gnome-terminal"] floating enable to no effect. Interestingly, the example in the user's guide with `xterm` works. Is it a GNOME-related issue? I'm running i3 4.7.2 on Ubuntu 13.10, installed via the repo listed on the site (`deb http//debian.sur5r.net/i3/ saucy universe`) (I can't publish links so I left the ':' out of the source here).Fri, 28 Mar 2014 16:05:02 +0000https://faq.i3wm.org/question/3586/floating-windows-with-for_window/https://faq.i3wm.org/question/3586/floating-windows-with-for_window/?answer=3590#post-id-3590The userguide says: > The first part of the WM_CLASS is the > instance ("irssi" in this example), > the second part is the class ("URxvt" > in this example). > > Should you have any problems with > assignments, make sure to check the i3 > logfile first (see > http://i3wm.org/docs/debugging.html). > It includes more details about the > matching process and the window’s > actual class, instance and title when > starting up. So, try this as a matcher: ``"Gnome-control-center"``. Sat, 29 Mar 2014 08:47:38 +0000https://faq.i3wm.org/question/3586/floating-windows-with-for_window/?answer=3590#post-id-3590
