I have configured Xubuntu 12.04 to login to terminal without any GUI/DisplayManager. I could see no process running related to XFCE in ps -eaf|grep -i xf*

But my memory consumption in top command does not show any significant improvements. In GUI mode, the system was taking up 340-350MB of RAM. In Terminal mode also it taking up the same RAM.

I thought of saving good amount of memory because of No GUI mode;but in vain. What could be the issue?

Please provide inputs.

Thanks, Harish Pathangay

why are you worried about the ram usage? is your PC abnormally slow? Linux will try to use all of your memory every time --- unused RAM is wasted RAM. –  Rmano Nov 16 '13 at 23:01
    
Which particular value of top are you using for the comparison? What do you see with top -b - n 1? You could put up the data with top -b -n 1 | pastebinit (but you need to sudo apt-get install pastebinit if you don't have pastebinit installed.) –  user25656 Nov 17 '13 at 6:17

You best bet is probably to install Ubuntu Server. It is designed to use software and hardware resources in a different way, resulting in less overall RAM and CPU usage for those who need a terminal-only or bare bones setup.

The Ubuntu Sever Edition is good. I misconstrued the output of TOP command. TOP command Used section reports the total allocated inclusive of caches and buffers which might not be actively used in a running process. I used free -m command to see the memory minus cached minus beffered. It is around 30-40MB only.

Thanks Again, Harish Pathangay
