I have laptop Asus N53SV with 4 GB of RAM, i7 with integrated card and dedicated GPU. My problem on Fedora is that system reports only 2.6 GB RAM. I know that I should use kernel with PAE but even after I install it, I have only 2.6 GB RAM avaiable. Now I use 3.0.0 rc6 kernel, but still nothing. Is it possible that the integrated GPU uses almost 1GB of RAM ? Can I check it somehow?
