Hi I'm new I just got this system half and hour ago and it' rocks but I have a question and a problem - where did the first few bits of my ram go to? it show's 7.77GB while i got 8.00GB and to rule out my GFX - it's a GTX nvidia 560M 2GB ver so i highly doubt a card with 2gb will take ram - but hey anything's possible and so far i'm enjoying the system and the fact that my numberpad doesn't work - the only number that does work when i do press shift is 5 so yea that's the only 2 things i see that are misbehaving / showing wrong info

Please paste your computer model, especially the graphics model number. Do you use mac computer?

Computer, RAM, and hard disc drive manufacturers use the (il)logic that 1000 MB * 1000MB=1GB. In reality, it is 1024 MB * 1024 MB =1048576 MB (or 1 GB).

I know that's hard to understand, so let me simplify: Hardware manufacturers like to overstate what they are actually selling you, so they decided that 1 does not equal 1, it equals 1.024.

So your saying that I actually have more than what I bargained for?

Yes and No. Yes because the real value of 8GB RAM is 7.45GiB RAM so theoretically you have 320 MiB RAM more.  

As C00ter already mentioned;

What is real is that manufacturers are using SI PREFIX-es (Metric prefixes) which means that GIGA = 1000³ = 10⁹ = 1000 000 000 something.
Computer world is using Binary prefix-es which means GIGA = 1024³ = 2³⁰ = 1 073 741 824 bytes. If you now calculate the exact amount of RAM on your computer:
8GB = 8 000 000 000 / 1024³ = 7.45 GiB or gibibyte.

Therefore, the computer shows "less" space than the manufacturers claim, and therefore the name GiB (in my upper example) instead of GB where i indicates binary prefix.

Never knew that ..that's some interesting info's and I have 1 other problem which I want to get working is that my keyboard backlight button's don't function is there a command to test to see if they even function under this system? I know they do in normal Ubuntu but that's about it

Yes and No. Yes because the real value of 8GB RAM is 7.45GiB RAM so theoretically you have 320 MiB RAM more.
