run in command line:

1. sudo fdisk -l to find the drive’s location e.g. /dev/sdf

3. sudo mkfs.ntfs -f /dev/sdf1

To manually start the cups service:

sudo service cups start

do solve this, remove kmod*

install akmod instead, problem solved,

configure nvidia using 

sudo nvidia-settings

download the themes

mkdir ~/.themes/ is it’s not there

unpack the themes to the above dir

now new themes should appear in configuration list

To install xfce:

sudo yum groupinstall XFCE

To install kde:

sudo yum install @kde-desktop

To remove kde:

sudo yum erase @kde-desktop

but this will remove gnome shell too, to get gnome back:

sudo yum install @gnome-desktop

1. get the source from http://cran.case.edu/

2. create a dir to unpack to

3. /build/dir/configure, in my case f77 and readline-devel are missing, get f77 complier by installing gcc-gfortran, get realine-devel by simply installing it

4. make, the executables are in /R/home/dir/bin, cp the “R” to $PATH, e.g. /usr/local/bin

5. run R in terminal by typing “R”

6. The x11-fonts in the plots do not display on my F15. To solve this, 

install xorg-x11-fonts-100dpi

install xorg-x11-fonts-75dpi

install xorg-x11-fonts-ISO8859-1-100dpi

install xorg-x11-fonts-ISO8859-1-75dpi

install kernel-devel
