Commen= t # 4 on bug 10488= 8 from Alex Deucher 
I believe setterm uses vesa vbi calls (i.e., calls into the le=
gacy vesa real
mode vbi interface) to blank the screen which only works on boards with a
legacy vbi interface (i.e., won't work UEFI systems).  Doing that goes behi=
nd
the driver's back and touches the hw directly.  Additionally, vbi support f=
or
multiple displays is pretty much non existent so even if your board supports
vbi, it's not likely to work if you have multiple displays or are using a
display configuration different from what came up at boot.
