[CentOS] Need help

Mon Mar 20 20:59:41 UTC 2017

Try another console like ALT-F2.  See if you have a black screen login prompt.  I opened a bug with RedHat for a system that when I went from 6.7 to 6.8 booted but would not start the X server.  Problem was in the MACH64 driver.  It is missing an external symbol that the X server requires.

This is a wild guess since the problem I had occurred on Ubuntu 16.04 LTS but the symptoms are identical.  Try 'systemctl enable console-getty.service' then 'systemctl start console-getty.service' or, if it is headless (serial console only), 'systemctl enable serial-getty at ttyS0.service' then 'systemctl start serial-getty at ttyS0.service' assuming it's ttyS0).  For VMs (specifically kvm/qemu) neither of these "solutions" worked.

I figured out that the system boots OK and it is possible
to login remotely. However the monitor does not start up.

Do you know how to fix it?
