My CentOS-6 based workstation is dying a slow death due to bit rot and
so I decided to swap out the existing disc drive for another. Given
that I had to reinstall anyway I decided that now was the time to try
out FreeBSD-11 as a desktop.
This Intel based system had UEFI enabled. Apparently this may have a
surprising, to me, effect on the video display used for the system
console in text mode. For whatever reason the boot process insists on
treating a 480x640 60Hz display as 800 x 480 at some other refresh
rate, probably 75Hz. This produces a difficult to read flickering
display and oddball presentation artifacts such as typing at a cursor
presented mid way from the top over existing text and displaying the
output at the bottom of the screen.
Is this a known phenomenon? Is there something that I am supposed to
do to get this to work properly or do I just disable UEFI?
