The default installation settings of xdm match those used for most platforms in the previous X.Org releases: Scripts & modules: $(libdir)/X11/xdm (aka $(prefix)/lib/X11/xdm) Configuration files: $(libdir)/X11/xdm Pixmap files: $(libdir)/X11/xdm/pixmaps Log files: /var/log Process id/lock files: /var/run xauth cookie files: /var/lib/xdm These may be overridden with the following options to configure: Loadable modules: --with-xdmlibdir Scripts: --with-xdmscriptdir (or --with-xdmlibdir) Configuration files: --with-xdmconfigdir (or --with-xdmlibdir) Pixmap files: --with-xdmpixmapdir (or --with-xdmlibdir) Log files: --with-logdir Process id/lock files: --with-piddir xauth cookie files: --with-authdir For instance, some packagers/sites may prefer: --with-xdmconfigdir=/etc/X11/xdm --with-xdmlibdir=$(prefix)/lib/xdm --with-xdmscriptdir=/etc/X11/xdm The handling of --with-utmp-file & --with-wtmp-file have also changed slightly since previous versions of xdm: --with-{u,w}tmp-file [default] write records to utmp/wtmp files, but allow sessreg to use its builtin default paths. Omits -u/-w flag entirely from sessreg command in Xstartup & Xreset files. --with-{u,w}tmp-file= write records to utmp/wtmp files at specified filename. Passes filename as argument to sessreg -u/-w flag in Xstartup/Xreset. --without-{u,w}tmp-file or --with-{u,w}tmp-file=none Do not write records to utmp/wtmp files at all. Passes "none" as argument to sessreg -u/-w flag in Xstartup/Xreset. ------------------------------------------------------------------------ All questions regarding this software should be directed at the Xorg mailing list: https://lists.x.org/mailman/listinfo/xorg The master development code repository can be found at: https://gitlab.freedesktop.org/xorg/app/xdm Please submit bug reports and requests to merge patches there.
