How to un-break graphical Java apps under Ratpoison

Many graphical Java apps will hang with a blank grey screen when started under Ratpoison and other non-reparenting window managers.

The workaround for this appalling brokenness is a very simple one, yet it took me three days of frustrated search – so I ought to post it:

  1. Install wmname.
  2. Spoof your window manager’s name string:
    wmname LG3D
  3. Use Java app, which now works.
