centoslinuxyum
I mistaken installed centos7 minimal. But I want to install GUI for Centos 7.From this link, I try the following commands:
yum groupinstall "GNOME Desktop" "Graphical Administration Tools"
But It is asking repoid, like:
yum-config-manager --disable <repoid>.
I don't know the repoid. How to get repoid for Centos 7?
Install GNOME Desktop Environment on here.
# yum -y groups install "GNOME Desktop"
Input a command like below after finishing installation:
# startx
GNOME Desktop Environment will start. For first booting, initial setup runs and you have to configure it for first time.
GNOME Desktop Environments starts like follows.
The default GNOME Desktop of CentOS 7 starts with classic mode but if you'd like to use GNOME Shell, set like follows:
Option A: If you start GNOME with startx, set like follows.
# echo "exec gnome-session" >> ~/.xinitrc
# startx
Option B: set the system graphical login systemctl set-default graphical.target (more info) and reboot the system. After system starts
Install KDE Desktop Environment on here.
# yum -y groups install "KDE Plasma Workspaces"
Input a command like below after finishing installation:
# echo "exec startkde" >> ~/.xinitrc
# startx
Install Cinnamon Desktop Environment on here.
First Add the EPEL Repository (EPEL Repository which is provided from Fedora project.)
Extra Packages for Enterprise Linux (EPEL)
How to add EPEL Repository?
# yum -y install epel-release
# sed -i -e "s/\]$/\]\npriority=5/g" /etc/yum.repos.d/epel.repo # set [priority=5]
# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/epel.repo # for another way, change to [enabled=0] and use it only when needed
# yum --enablerepo=epel install [Package] # if [enabled=0], input a command to use the repository
And now install the Cinnamon Desktop Environment from EPEL Repository:
# yum --enablerepo=epel -y install cinnamon*
Input a command like below after finishing installation:
# echo "exec /usr/bin/cinnamon-session" >> ~/.xinitrc
# startx
Cinnamon Desktop Environment will start. For first booting, initial setup runs and you have to configure it for first time.
Cinnamon Desktop Environment starts like follows.
Install MATE Desktop Environment on here (You will need to add the EPEL Repository as explained above in advance).
# yum --enablerepo=epel -y groups install "MATE Desktop"
Input a command like below after finishing installation:
# echo "exec /usr/bin/mate-session" >> ~/.xinitrc
# startx
Install Xfce Desktop Environment on here (You will need to add the EPEL Repository as like above in "Cinnamon" installation before).
# yum -y groupinstall X11
# yum --enablerepo=epel -y groups install "Xfce"
Input a command like below after finishing installation:
# echo "exec /usr/bin/xfce4-session" >> ~/.xinitrc
# startx
I found this helpful for installing OpenCL: https://www.centos.org/forums/viewtopic.php?t=63270#p266493
Which led me to run:
$ yum install opencl-headers
$ yum provides '*/libOpenCL.so'
Loaded plugins: priorities, update-motd, upgrade-helper
epel
...
ocl-icd-devel-2.2.12-1.el6.i686 : Development files for ocl-icd
Repo : epel
Matched from:
Filename : /usr/lib/libOpenCL.so
ocl-icd-devel-2.2.12-1.el6.x86_64 : Development files for ocl-icd
Repo : epel
Matched from:
Filename : /usr/lib64/libOpenCL.so
and thus:
$ sudo yum install ocl-icd
There remains an issue in which you may need to symlink whatever libOpenCL.so you install to /usr/lib/ I think? I was able to solve my installation problem after I ran:
$ sudo ln -s /usr/lib64/libOpenCL.so.1 /usr/lib/libOpenCL.so
