[ubuntu] proxy settings for multiple locations ?

http://ubuntuforums.org – Hi, just upgraded fron 10.04 LTS to 12.04.1 LTS and I have a problem with the (minimalistic) approach for setting the system wide proxy settings. I travel a lot and work in different environments each requiring different proxy settings with and without authenticitation as well as at home where I have no proxy. In 10.04 LTS, I used to be able to save the configurations in the proxy-setting GUI and just select the one I needed and apply it system wide. For sure, some things were not fully integrated (apt-get, synaptic, IDLE (pyhton), ...) for which I then manually had to set it right (o (Hardware)
