Colin Watson 8fc4fa45c5 Preferred resolution detection for VBE. 
* grub-core/video/video.c (grub_video_edid_checksum): New function.
(grub_video_edid_preferred_mode): Likewise.  Try EDID followed by
the Flat Panel extension, in line with the X.org VESA driver.
* grub-core/video/i386/pc/vbe.c (grub_vbe_bios_get_flat_panel_info):
New function.
(grub_vbe_bios_get_ddc_capabilities): Likewise.
(grub_vbe_bios_read_edid): Likewise.
(grub_vbe_get_preferred_mode): Likewise.
(grub_video_vbe_setup): When the mode is "auto", try to get the
preferred mode from VBE, and use the largest mode that is no larger
than the preferred mode (some BIOSes expose a preferred mode that is
not in their mode list!).  If this fails, fall back to 640x480 as a
safe conservative choice.
(grub_video_vbe_get_edid): New function.
(grub_video_vbe_adapter): Add get_edid.
* include/grub/video.h (struct grub_vbe_edid_info): New structure.
(struct grub_video_adapter): Add get_edid.
(grub_video_edid_checksum): Add prototype.
(grub_video_edid_preferred_mode): Likewise.
* include/grub/i386/pc/vbe.h (struct grub_vbe_flat_panel_info): New
structure.

* grub-core/commands/videoinfo.c (print_edid): New function.
(grub_cmd_videoinfo): Print EDID if available.

* util/grub.d/00_header.in (GRUB_GFXMODE): Default to "auto".  This
is more appropriate on a wider range of platforms than 640x480.
* docs/grub.texi (Simple configuration): Update GRUB_GFXMODE
documentation.

README 

This is GRUB 2, the second version of the GRand Unified Bootloader.
GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more
robust, more powerful, and more portable.

See the file NEWS for a description of recent changes to GRUB 2.

See the file INSTALL for instructions on how to build and install the
GRUB 2 data and program files.

Please visit the official web page of GRUB 2, for more information.
The URL is <http://www.gnu.org/software/grub/grub.html>.

More extensive documentation is available in the Info manual,
accessible using 'info grub' after building and installing GRUB 2.
Please look at the GRUB Wiki <http://grub.enbug.org> for testing
procedures.

There are a number of important user-visible differences from the
first version of GRUB, now known as GRUB Legacy. For a summary, please
see:
