New Revision: 268772
URL: http://svnweb.freebsd.org/changeset/base/268772
Log:
Allow efifb to be used with xf86-video-scfb. This is important for EFI
systems without either a CSM or real graphics drivers, such as my Lenovo
Haswell laptop.
This provides working X with the small complication of a console cursor
permanently overlaid on the upper-left corner of the screen that will be
dealt with later.
Also remove some redundant screen clearing.
