To my understanding, when you install centos-7 with options ServerGUI or
GNOME Desktop and leave the system for long time locked, you will notice
that CentOS slips into textual interface mode and you will not be able to
get GUI which means, you can login to the system and cannot see GUI screen.
I have found the following steps on google, which helped me get through
this problem
systemctl disable gdm.service
systemctl enable lightdm.service
systemctl set-default graphical.target
First command was successful, second one error'd out. Not sure what to do,
i reverted back the first command and executed the third command and
rebooted. All worked fine !
Below is the log -
[root@buildhost ~]# systemctl disable gdm.service
Removed symlink /etc/systemd/system/display-manager.service.
[root@buildhost ~]# systemctl enable lightdm.service
Failed to execute operation: Access denied
[root@buildhost ~]# systemctl disable gdm.service
[root@buildhost ~]# systemctl enable gdm.service
Created symlink from /etc/systemd/system/display-manager.service to
/usr/lib/systemd/system/gdm.service.
[root@buildhost ~]# systemctl set-default graphical.target
Removed symlink /etc/systemd/system/default.target.
I think, the last command made sense to me.
