Upgrade to Fedora Linux 21

I had been using Fedora version 20 for most of year 2014. Fedora 21 was a welcome change for a few reasons.

1. I didn’t need to install the Nvidia video card driver. In Fedora 20 without this driver, the GPU fan would spin at top speed and was really noisy. With the driver the spinning would slow down just moments before the login screen would pop up. But with Fedora 21, the GPU fan slows down in a few seconds just after Linux starts to boot.
2. I’m finally satisfied using the default Gnome 3 Desktop GUI. But it involved some tweaking.
• I had to manually install with Yum dconf-editor and gnome-tweak-tool
• I used dconf-editor application to change org.gnome.nautilus.preferences key and set the option to check the “sort-directories-first”” The default mixed the directories with files — something I don’t like.
• I used the gnome-tweak-tool application to enlarge certain screen fonts to make it easier for me to read. And I used this took to add startup applications I like such as calc and Deluge.
3. Using the default Gnome 3 Desktop gui gives me notification of updates. In Fedora 20 I used Mate Desktop which for some reason did not give me notification of updates. I had to update manually about once a week.
4. The system seems to be faster. The Mint menu in the Mate Desktop gui was so slow to load.
