I have 2 x 2 GB memory sticks in my machine, why does System Monitor report 3.8 GiB? Where is the other memory going? Even if it is being used by the kernel, it seems that the system should report 4096 MB.
There have been a number of posts from people using Fedora asking essentially the same question that I am about to ask. With that in mind, it seems unlikely that I will get an answer.
I have had my box running fedora 17 headless for some time now. I just reinstalled it with fedora 20. I modified the "default.desktop" link to point to multi-user. As long as a monitor is attached it boots fine. When I disconnect the monitor and reboot, I am never able to get into the system.
