RAM not shown right

[nitewalker]

I have a Acer Aspire 5100 with AMD Turion 64x2 processor, came with 1 gb RAM, I just updated RAM to 4 gb but when I check it doesn't show it? What do I need to do.....I am running Kubuntu 8.10.....below are results of runing "free -m" and "free".

Re: RAM not shown right

Look in /var/log/syslog and you will see a line something like this
