7.1. Silicon Graphics startup   

When X starts up, xdm will execute a shell script typically found in /usr/lib/X11/xdm/Xsession. On the Silicon Graphics machines it looks like:

      #!/bin/sh

      dim="`xdpyinfo | awk ' /dimensions/ {print $2}'`"

      if [ "$dim" = "1024x768" ]; then

          geom="80x40+190+102"

          font="-sgi-terminal-*-*-*--12-*"

      else

          geom="80x40+150+172"

          font="-sgi-terminal-*-*-*--17-*"

      fi
