I use the xf86-video-scfb driver, VESA driver doesn' coop with the resolution of my
display (called Full HD, 1980x1080 pixel). VESA complains about not know resolution when
starting.

The SCFB is unusable. The i5-4200M CPU has enough stamina to do well, but when it comes
to video/desktop/graphics under load, the graphics is rendered unusable. 


The laptop is not productive and an expensive heap of plastic, silica and metal with
FreeBSD that way.
