Configure console menu colors
As of DebianWheezy, there is no support for easily modifying the colors of the console menu. /etc/default/grub does not have any variables that can set the colors for this video mode.
The easiest way to modify the console menu colors is to create a new file /boot/grub/custom.cfg and put your configurations there:
The variables that control the console menu colors are the following:
color_normal - the “normal” foreground and background terminal colors
color_highlight - the “highlight” foreground and background terminal colors
menu_color_normal - the foreground and background colors to be used for non-highlighted menu entries
menu_color_highlight - the foreground and background colors to be used for the highlighted menu entry
If you configured /boot/grub/custom.cfg, there is no need to run update-grub; the file will be automatically loaded by /boot/grub/grub.conf at boot.
Configure graphical splashimage
install the grub2-splashimages package: aptitude install grub2-splashimages
- choose one of the nice images to use as the splashimage. You can look at the images with any image viewer (Ex: display)
configure/add the GRUB_BACKGROUND variable in /etc/default/grub. Ex: GRUB_BACKGROUND="/usr/share/images/grub/Lake_mapourika_NZ.tga"
make sure that GRUB_TERMINAL=console is commented out. The graphical mode will not be enabled if this is uncommented. By default it's commented, so you shouldn't worry too much.
the graphical resolution can be changed via the variable GRUB_GFXMODE
- reboot to observe the change
