put this in /etc/bash.bashrc for monodevelop to work:

export MOZILLA_FIVE_HOME=/usr/bin/mozilla

If your laptop takes too long to configure network interfaces, especially when you are not on an network, you can stop it from waiting by hitting Ctrl+C. This will cause this step to be skipped.

On a more permanent basis, you can modify the amount of time your computer waits for network configuration as follows:

Edit /etc/dhcp3/dhclient.conf

Edit the line that says:
#timeout 60
to read
timeout 20

Now your laptop will only try for 20 seconds to configure the network interfaces. 20 seconds is ample time for my laptop’s network interfaces to get configured. (I actually use nm-applet, but that is another story…)

If you want to disable the configuration of the ethernet network interface (eth0) at startup, edit “/etc/network/interfaces” and comment out the line “auto eth0“. You will have to bring up eth0 manually later, by doing $sudo ifup eth0 whenever you are plugged into the network.
