First do numbers 1 and 2 above. Then unpack the required archives:
# cd /usr/X11R6
# for i in bin fnts lib xicf; do
# gnutar -xzpPf X33$i.tgz
# done
Then unpack a server archive corresponding to your vga card. The
server man pages, X11R6/man/man1/XF86_*
, list the vga chip
sets supported by each server. For example, if you have an ET4000
based card you will use the XF86_SVGA server:
# gnutar -xzpPf X33SVGA.tgz
# cd /usr/X11R6/bin; rm -f X; ln -s XF86_SVGA X
