 v11 How does that work? When you start root in your build directory, it reads .rootrc in your build directory. This file points to rootlogon.C in your build directory. This macro is executed when on root startup and loads the shared object lib/libmars.so. As all this uses absoluet paths, you could even move .rootrc into your home directory and get the Mars environment no matter where you start root. As this works only with absolute paths, you might not change or rename the build directory without changing those files. == Tipp == Lately, on modern screens, the default GUI fonts of root (10 and 12) are exceptionally small. They can be changed by adding the following lines to your .rootrc. As root is always using the one in your home directory additonally, it is advisable to add these lines to your global .rootrc. {{{ Gui.DefaultFont:            -*-helvetica-*-r-*-*-18-*-*-*-*-*-iso8859-1 Gui.MenuFont:               -*-helvetica-*-r-*-*-18-*-*-*-*-*-iso8859-1 Gui.MenuHiFont:             -*-helvetica-bold-r-*-*-18-*-*-*-*-*-iso8859-1 Gui.DocFixedFont:           -*-courier-*-r-*-*-18-*-*-*-*-*-iso8859-1 Gui.DocPropFont:            -*-helvetica-*-r-*-*-18-*-*-*-*-*-iso8859-1 Gui.IconFont:               -*-helvetica-*-r-*-*-16-*-*-*-*-*-iso8859-1 Gui.StatusFont:             -*-helvetica-*-r-*-*-16-*-*-*-*-*-iso8859-1 }}}
