XCOMM!SHELL_CMD XCOMM XCOMM This is just a sample implementation of a slightly less primitive XCOMM interface than xinit. It looks for XINITRC and XSERVERRC environment XCOMM variables, then user .xinitrc and .xserverrc files, and then system XCOMM xinitrc and xserverrc files, else lets xinit choose its default. XCOMM The system xinitrc should probably do things like check for XCOMM .Xresources files and merge them in, start up a window manager, and XCOMM pop a clock and several xterms. XCOMM XCOMM Site administrators are STRONGLY urged to write nicer versions. XCOMM unset SESSION_MANAGER #ifdef __APPLE__ XCOMM Check for /usr/bin/X11 and BINDIR in the path, if not add them. XCOMM This allows startx to be placed in a place like /usr/bin or /usr/local/bin XCOMM and people may use X without changing their PATH. XCOMM Note that we put our own bin directory at the front of the path, and XCOMM the standard system path at the back, since if you are using the Xorg XCOMM server there's a pretty good chance you want to bias the Xorg clients XCOMM over the old system's clients. XCOMM First our compiled path bindir=__bindir__ case $PATH in *:$bindir | *:$bindir:* | $bindir:*) ;; *) PATH=$bindir:$PATH ;; esac XCOMM Now the "old" compiled path oldbindir=/usr/X11R6/bin if [ -d "$oldbindir" ] ; then case $PATH in *:$oldbindir | *:$oldbindir:* | $oldbindir:*) ;; *) PATH=$PATH:$oldbindir ;; esac fi XCOMM Bourne shell does not automatically export modified environment variables XCOMM so export the new PATH just in case the user changes the shell export PATH #endif userclientrc=$HOME/.xinitrc [ -f "${XINITRC}" ] && userclientrc="${XINITRC}" sysclientrc=XINITDIR/xinitrc userserverrc=$HOME/.xserverrc [ -f "${XSERVERRC}" ] && userclientrc="${XSERVERRC}" sysserverrc=XINITDIR/xserverrc defaultclient=XTERM defaultserver=XSERVER defaultclientargs="" defaultserverargs="" defaultdisplay="" clientargs="" serverargs="" vtarg="" #ifdef __APPLE__ if [ "x$X11_PREFS_DOMAIN" = x ] ; then export X11_PREFS_DOMAIN=BUNDLE_ID_PREFIX".X11" fi XCOMM Initialize defaults (this will cut down on "safe" error messages) if ! defaults read $X11_PREFS_DOMAIN cache_fonts > /dev/null 2>&1 ; then defaults write $X11_PREFS_DOMAIN cache_fonts -bool true fi if ! defaults read $X11_PREFS_DOMAIN no_auth > /dev/null 2>&1 ; then defaults write $X11_PREFS_DOMAIN no_auth -bool false fi if ! defaults read $X11_PREFS_DOMAIN nolisten_tcp > /dev/null 2>&1 ; then defaults write $X11_PREFS_DOMAIN nolisten_tcp -bool true fi if ! defaults read $X11_PREFS_DOMAIN enable_iglx > /dev/null 2>&1 ; then defaults write $X11_PREFS_DOMAIN enable_iglx -bool false fi XCOMM First, start caching fonts if [ x`defaults read $X11_PREFS_DOMAIN cache_fonts` = x1 ] ; then if [ -x $bindir/font_cache ] ; then $bindir/font_cache elif [ -x $bindir/font_cache.sh ] ; then $bindir/font_cache.sh elif [ -x $bindir/fc-cache ] ; then $bindir/fc-cache fi fi if [ -x __libexecdir__/privileged_startx ] ; then XCOMM Don't push this into the background because it can cause XCOMM a race to create /tmp/.X11-unix __libexecdir__/privileged_startx fi if [ x`defaults read $X11_PREFS_DOMAIN no_auth` = x0 ] ; then enable_xauth=1 else enable_xauth=0 fi if [ x`defaults read $X11_PREFS_DOMAIN nolisten_tcp` = x1 ] ; then defaultserverargs="$defaultserverargs -nolisten tcp" else defaultserverargs="$defaultserverargs -listen tcp" fi if [ x`defaults read $X11_PREFS_DOMAIN enable_iglx` = x1 ] ; then defaultserverargs="$defaultserverargs +iglx +extension GLX" else defaultserverargs="$defaultserverargs -iglx" fi XCOMM The second check is the real one.
