lightdm Installation
Add a new source repository:
# rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm # yum install lightdm-gtk |
lightdm Configuration
Configure the /etc/lightdm/lightdm.conf file as follows. If the file does not exist, create it.
[XDMCPserver] enabled=true |
Change Default Display Manager to lightdm
# systemctl disable gdm ; systemctl enable lightdm |
Though gdm is disabled, it is still running and will need to be stopped replaced by lightdm (This is unnecessary if you initiated a reboot after Step 3)
# systemctl stop gdm; sleep 3; systemctl start lightdm |
Temporarily Disable Firewall to Test Connection
# systemctl stop firewalld.service |
Open UDP port 177 from the PC to the remote host direction. Refer to your OS manual for support concerning your firewall.
Add a New Source Repository (If you already installed it above, you can skip this step)
# rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm |
Install New Desktop User Environment (Choose one or the other)
Xfce Installation
# yum groupinstall xfce (In some case --skip-broken option is needed.) |
KDE Installation(Optional)
# yum groupinstall kde-desktop |
Apply New Environment and Restart XDMCP Daemon
# systemctl restart lightdm |
