Lokasi dari file konfigurasi untuk X tergantung pada keluaran (release) tertentu dan distributi yang anda punyai. Lokasinya mungkin adalah /etc/Xconfig, /etc/XF86Config atau /usr/X11/lib/XF86Config. Anda seharusnya bisa melihatnya pada saat memulai X -- hal tersebut akan ditampilkan pada screen sebelum seluruh pilihan ditayangkan. Syntax antara file-file XF86Config dan Xconfig sedikit berbeda, sehingga keduanya dimasukkan pada distribusi.
