Forum Ubuntu-it

Salve a tutti ho appena installato ubuntu 7.10 e volevo installare gli ultimi driver x la mia ati x1600 mobility
ho seguito passo passo la guida : http://forum.ubuntu-it.org/viewtopic.php?t=132600
ho installato i driver e tutto ok
arrivato al punto che dice:  "Prima di riavviare una piccola nota dedicata a tutti coloro che prima di questi driver utilizzavano quelli presenti nei repository ufficiali è necessario disabilitare i vecchi sostituendo all'interno del file"
quando do il comando mi esce

# This file is sourced from the linux-restricted-modules-common init
# script and is used to disable the link-on-boot feature, one module
# at a time.  This can be useful if you want to use hand-compiled
# versions of one or more modules, but keep linux-restricted-modules
# installed on your system, or just to disable modules you don't use
# and speed up your boot process by a second or two.
#
# Use a space-separated list of modules you wish to not have linked
# on boot.  The following example shows a (condensed) list of all
# modules shipped in the linux-restricted-modules packages:
#
# DISABLED_MODULES="ath_hal fc fglrx ltm nv"
#
# Note that disabling "fc" disables all fcdsl drivers, "ltm" disables
# ltmodem and ltserial, and "nv" disables the three nvidia drivers.
# You can also name each module individually, if you prefer a subset.

DISABLED_MODULES=""

come faccio a modificare la stringa  DISABLED_MODULES=""  in  DISABLED_MODULES="fglrx"  ??
giustamente ora se do il comando fglrxinfo mi esce:
fglrxinfo: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

ma penso sia dovuto al fatto che nn riesco  amodificare la rifa di prima..
help! tnx a tutti

al posto di nano digita sudo gedit /etc/default/linux-restricted-modules-common 
cosi potrai modificare il file a tuo piacere, ciao

niente da fare ho digitato e ho modificato il file in questo modo:

DISABLED_MODULES="fglrx"

ho sbagliato o ho fatto bene?
cmq quando do mi esce sempre :

fabrizio@Toshiba:~$ fglrxinfo
fglrxinfo: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory

che significa?
