One of the console driver patches for Esix 4.0.3A causes the XFree86
server's default keymap to be corrupted. If you are being affected by
this problem it will be obvious because few (if any) of the keys will be
mapped correctly. There are two solutions to this. One is to remove the
console driver patch which introduced the problem. The second is to use
xmodmap(1) to reset the default mapping after server startup. The default
mapping is provided in the file
/usr/X11R6/lib/X11/etc/xmodmap.std, and can
be installed automatically by adding the line:
xmodmap /usr/X11R6/lib/X11/etc/xmodmap.std
.xinitrc file (or your Xsetup file if using xdm).
