Fw: console screen
Hi,
After upgrading to squeeze and Grub2 my old line:
# defoptions=vga=791
in the menu.lst file is no longer relevant and I am supposed to do something with the
/etc/default/grub file. In there it states:
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480
If I set this at 1280x1024, which I know my server supports, will that roughly give me what I had?
In the meantime after re-reading the post at
http://harrison3001.blogspot.com/2009/09/grub-2-graphical-boot-tips-to-set.html it seems that
GRUB_GFXMODE line is only for the grub menu itself and NOT for the console screen after that.
Is there a better solution in Squeeze 6.0.2, which we have reached by now, or do I indeed need to
modify the /etc/grub.d/00_header file? The instructions in the article above show a different set of
lines in the original 00_header file then what I have overhere.
------<article quote>-------------
set gfxmode=${GRUB_GFXMODE} <-- FIND THIS LINE
(as you note GRUB_GFXMODE is the variable we set before through /etc/default/grub)
set gfxpayload=keep <-- THIS IS FOR THE VGA CONSOLE!
(as you note the statement keep, obviously, keeps, what?, the resolution we set before through
GRUB_GFXMODE variable set into /etc/default/grub)
insmod gfxterm
insmod ${GRUB_VIDEO_BACKEND}
------<end quote>-------------
------<00_header quote>-------------
if loadfont `make_system_path_relative_to_its_root "${GRUB_FONT_PATH}"` ; then
set gfxmode=${GRUB_GFXMODE}
load_video
insmod gfxterm
fi
------<end quote>-------------
As you can see in Squeeze 6.0.2. there is an extra load_video line before the insmod gfxterm. It
seems the VIDEO_BACKEND lines are moved to that procedure.
However, that GRUB_VIDEO_BACKEND just seems to appear out of the blue, it is not listed in the
default /etc/default/grub, nor does it get set anywhere within the /etc/grub.d/00_header file. I
suppose I one wants to use that one simply "knows" what to do and the set it in the proper script
file.
Should the end result be something like this
------<00_header.new quote>-------------
if loadfont `make_system_path_relative_to_its_root "${GRUB_FONT_PATH}"` ; then
set gfxmode=${GRUB_GFXMODE}
set gfxpayload=keep
load_video
insmod gfxterm
fi
------<end quote>-------------
for what I want, to have a console with more and longer lines?
As I have no test servers nearby I need to know what I am doing before I start modifying things. :-(
p.s. Anybody know if the grub2 team is working on this, to have a "generic" way, maybe via the
/etc/default/grub file , to set the console resolution?
