GIMP is a great program, but I always found it was a bit annoying to use on OS X (Leopard). First of all, whenever X11 starts, a new xterm window along with it. Besides that, when switching windows you need two clicks before GIMP (or any other program, really) registers the click and actually does something - the first click just switches the active window. Seeing as GIMP has it's tool palette in a separate window, this quickly became extremely irritating.
After a quick google, I found many sources saying that to disable xterm, I needed to copy /private/etc/X11/xinit/xinitrc to ~/.xinitrc and edit out the "xterm &" line inside. That's easy enough, but the only problem is that on Leopard with the latest X11 from XQuartz (22.214.171.124 at the time of writing) installed, /private/etc/X11/xinit/xinitrc doesn't exist! Although /usr/X11/lib/X11/xinit/xinitrc does, editing out all references to xterm doesn't work anyways. Instead, the app_to_run preference needs to be modified:
defaults write org.x.X11 app_to_run /usr/bin/true
/usr/bin/true is a command that does nothing (literally), so this essentially tells X11 to autostart nothing. I moved onto my next problem and found that to solve the two-clicks problem, the solution was to enable the "focus follows mouse" option like this:
defaults write org.x.x11 FocusFollowsMouse -string YES
I've been using that for a few months and I find it's still pretty annoying, but it's still less annoying than having to click twice on everything. Fortunately, I recently discovered the "wm_click_through" preference which is exactly what I had been looking for all along:
defaults write org.x.x11 FocusFollowsMouse -string NO
defaults write org.x.X11 wm_click_through -bool true
Now X11's window focus is back to normal, and clicking on inactive windows works as expected; it switches the window and activates the widget you clicked on. Problems solved!
Thanks for your post. However
Thanks for your post. However you can accomplish the same going to X11 preferences pane (I've got OSX 10.6 Snow Leopard)
