Why does Ubuntu only show 3GB of RAM?
I recently upgraded my system from 2 to 4 GB of memory. When I booted into Ubuntu, it's only recognizing 3 GB.
I followed some instructions on adding the PAE; now when I boot up my kernel has switched from generic to PAE but I'm still only showing 3 GB. How do I get it to read all 4 GB?
I went to the Software Center and found the PAE, then when I clicked "More info" it shows a few more packages with it but they aren't checked. Should I check them to be added also? Will this make Ubuntu recognize my 4 GB?
