Additionally, with some video switches, changes in resolution 
cause problems.  I add the following to the right end of the 
'kernel' line as well:
	nomodeset vga=769

to force a TUI console which is not rendered in whatever font 
the system and video card think they can do, but rather a 
historically familiar: 
	80 x 24

grub [older RHEL derived] will pick this up by default; grub2 
[RHEL 7 derived] needs an edit in:
	/etc/sysconfig/grub

thus:
	GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap 
		vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root 
		crashkernel=auto  vconsole.keymap=us nomodeset vga=769 "

and ** then ** an express bootloader fixup:
	grub2-mkconfig -o /boot/grub2/grub.cfg
