Network manager in Ubuntu 10.10

Not sure which version of Ubuntu has this been implemented.


# Previously

sudo etc/init.d/NetworkManager stop

# Updated

sudo etc/init.d/network-manager stop


Enabling bash completion

Uncomment the following in /etc/bash.bashrc


if [ -f /etc/bash_completion ]; then
. /etc/bash_completion
f


Hijacked keyboard shortcut

Somehow when I upgraded to Ubuntu 10.10, my "Shift + f" launches firefox.

Apparently that keybinding was assigned to run command_1 in metacity which was assigned to launch firefox. To disable it go to,

gconf > apps > metacity > global_keybindings
