# X11 framebuffer driver from Gerd Knorr.
# You have to enable CONFIG_FB (UML-specific options/Graphics support/
# Support for frabe buffer devices), disable CONFIG_VGA_CONSOLE
# (UML-specific options/Graphics support/Console display driver support/
# VGA text console), and enable Framebuffer Console support (in the same

# 'x11=<width>x<height>
