Changed focus behaviour to no-click-to-focus by executing:
defaults write com.apple.x11 wm_ffm true in an
xterm or terminal (see the associated X11
FAQ). The X11.app needs to be restarted for the change
to take effect.
Created my own ~/.xinitrc by copying the
standard /etc/X11/xinit/xinitrc (see FAQ)
and adding the two lines:
right before the quartz windows manager is started with
The former line to switch the middle and the right mouse
button (so middle will paste) and the latter line to allow
various machines to display X11 applications on my mac.
Disabled key equivalents under X11 in the X11.app
Preferences (Input tab) so that Command modifier can be
used as Meta modifier in X11 applications (emacs in particular).
