Hi Sebastian,
I can propose a way to automatically suspend/unsuspend application
when it loses/regains its focus.
Please take a look at this snippet.
local signal = require("posix.signal")
....
awful.rules.rules = {
{ rule = { class = "Firefox" },
callback = function(c)
c:connect_signal("unfocus", function () signal.kill(c.pid,
signal.SIGSTOP); end);
c:connect_signal("focus", function () signal.kill(c.pid,
signal.SIGCONT); end);
end}
}
I'm not sure that automatic process suspension will play nicely with
all applications, but you could try and see for yourself.
