Hello,
I have the same problem again today with CentOS-7.
I re-installed with GNOME Desktop and also configured two VMs in it, all
was working fine and i left the system locked overnight. When i tried to
unlock the next day morning, screen only shows up black. Again, i cannot
see the GUI. I can login to the system though.
Any help would be appreciated here.
Thanks,
VB
