    Command line only skin/mode?

    I recently installed ubuntu 12.04 and kubuntu-desktop on a macbook pro and although I am enjoying them, I am getting horrendous battery life using them.

    Since I am mainly using terminal only, I was wondering if there was an interface or something I could download where I could log out and log into a shell only environment? I will occasionally need to look something up on the internet, so I would want to be able to switch back to something where I can use a browser.

    I am aware I can boot into text mode by altering the kernel boot line; however, I have problems when exiting it, the ubuntu/kubuntu dektop does not appear (just by background image), and I can't get back to the text mode easily.

    I am mainly interested in doing this so I can choose to save some battery power by using the shell only mode when I know I will be working in it for a long time, so I don't waste power displaying all the openGL graphics.

    I don't know how to set it to log in terminal by default, but you can log in a terminal-only desktop by pressing Ctrl + Alt + F1 at logon.

    I can get it to boot into text mode ok, it's just from there it's not really practical if I want to use a webrowser occasionally and then jump back etc. I was wanting to install something that could maybe be on the ubuntu login drop down menu of interfaces that I can log into (like I have KDA Plasma Workspace, Ubuntu, and Ubuntu 2D at the moment), and then I could simply log out and log back in to ubuntu or kubuntu etc.

    Ctrl + Alt + F1 doesn't seem to work for me, do you mean on the logon screen?

    I may have missed the point here but if your aim is to conserve resources I'm not sure that simply switching away to a virtual terminal (while leaving the X session and all the trimmings running in VT7) is really going to do anything for you.

    You could boot into console mode and then startx manually as/when required OR (I have never tried it) in principle you could do something like this

    http://askubuntu.com/questions/77191...fined-sessions

    and then create a simple xinitrc file that loads a lightweight wm and an xterm

    Or you could simply make the jump to a less resource hungry desktop like xfce or openbox.

    If you use top to look at CPU/MEM as a measure of resource consumption, using the tty consoles takes almost no resources. The X server requires some resources...but it's the applications that use X that really hog all the cycles (and increase power consumption).

    So you can use a tty, and the unused X server will be a trivial drain. But if you start loading up X with firefox and empathy and other stuff, you will consume a lot more.

    The 'powertop' package is a great resource for discovering settings on your system that can be changed to increase battery life.
