Try running 'dmesg | grep -in Memory' in a console; one of the lines will read something like "Memory: 1029372k/1048512k available (...)". In this example, 1048512k would be the total amount detected and usable by the kernel.
Some of it is reserved and therefore doesn't show up as available/installed memory to the rest of the system (including applications such as 'free' or system monitors). -- Ubuntu Does Not See All My Memory https://launchpad.net/bugs/87957 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
