Title:
  XDM does not work with IceWM

Status in xdm package in Ubuntu:
  New

Bug description:
  IceWM requires that XDG_DATA_DIRS be set so that libgdk-pixbuf2.0 can
  find the MIME cache. This is required to load images/pixmaps used for
  icons by IceWM (window decorations, minimize/maximize/close buttons).

  Setting XDG_DATA_DIRS appears to be the job of x11-common
  (/etc/X11/Xsession.d/60x11-common-xdg_path). x11-common does not set
  the XDG_DATA_DIRS environment variable to its default
  (DEFAULT_XDG_DATA_DIRS='/usr/local/share/:/usr/share/') if the
  DESKTOP_SESSION environment variable is not set by the display
  manager. XDM does not set the DESTKOP_SESSION environment variable, so
  IceWM windows and the IceWM taskbar do not display correctly since
  IceWM is unable to load the required pixmaps/images.

  The function which fails is gdk_pixbuf_new_from_file() (called in
  IceWM's yimage_gdk.cc), and provides an error message like "Couldn't
  recognize the image file format for file
  '/usr/share/icewm/themes/icedesert/closeI.xpm'". IceWM "helpfully"
  converts this error message to something like "IceWM: Warning: Out of
  memory for image /usr/share/icewm/themes/icedesert/closeI.xpm", which
  is a separate bug.

  Other display managers (GDM, lightdm) do set DESKTOP_SESSION, so IceWM
  works as expected with these display managers. Since the combination
  of XDM and IceWM does not work, it looks like XDM should be setting
  the DESKTOP_SESSION environment variable, at least when configured for
  use with IceWM.
