OpenSUSE 11.4 will not let me edit 50-blacklist.conf !

I need to add the following line in /etc/modprobe.d/50-blacklist.conf …

blacklist acer-wmi

in order to get wlan working, but I cannot seem to edit the file .

I tried:

sudo gedit /etc/modprobe.d/50-blacklist.conf

and got:

(gedit:30088): Gtk-WARNING **: cannot open display:

I also tried manually opening the file but it is read-only . (I did not set my root folder to read-only, however .)
I even wrote a script in /home/exo/.gnome2/nautilus-scripts that should let me open files as root, but nothing works …

This is my script:

gnomesu gnome-open "$uri" &

*Please note that I am brand-new to OpenSUSE but am an intermediate Debian user .

Use ‘gnomesu gedit /etc/modprobe.d/50-blacklist.conf’ instead.
