Even on the headless Odroid-HC1!
Pablo,
thanks for getting the Xfce group into epel!
Steps I took was:
Add epel repo per the CentOS arm web site.
yum groupinstall xfce
This should be enough for those of you with a standard video console. But the HC1 is headless, and if you also want to use vnc....
first follow the instructions to install vncserver per my instructions at
http://medon.htt-consult.com/Centos7-armv7.html
I will be updating this...
log into the user account.
run vncpasswd
You typically have to do this after installing vncserver and before starting it.
after getting a successful start of vncserver (may take a system reboot), log into the user account, and edit ~/.vnc/xstartup,
delete the last two lines and append:
exec /bin/sh /etc/xdg/xfce4/xinitrc xrdb $HOME/.Xresources startxfce4 &
restart vncserver and you can now vnc into your server. Even a headless HC1.
