Description: Whenever we install a new kernel or a driver, etc GRUB automatically generates a configuration file "grub.cfg" It makes a lot of output and can repeat itself. We can simplify it greatly. There is an example of a modified file for a Multi OS booting list included in the package. Screenshot 1 shows a cleaned up menu. Screenshot 2 shows a machine generated list Screenshot 3 a modified file showing a background image.
This app will reset grub to the grub menu file modified by the user Unless one wants to run the previous kernel this modified file will never have to be changed The reset script creates a backup with a time-stamp of the new machine generated grub.cfg file Then it overwrites grub.cfg with our modified file grub.cfg.mod Then it shows a simulation of the boot menu as proof of the reset
Prerequisites are that 'zenity' and 'grub-emu' are installed and that the user saves the original file: /boot/grub/grub.cfg to /boot/grub/grub.cfg.orig that the user modifies the original file and saves it to: /boot/grub/grub.cfg.mod There is instructions on the modification included in the package
Installing the app is just a matter of copying via a terminal: For Ubuntu 18.04 and later do this first: sudo mkdir /usr/share/images For earlier Ubuntus, including 4 CLIX 9 or Ubuntu-16.04, which already have this folder, we can start at this step > Extract downloaded file: Reset-Grub.tar.gz Open a terminal inside newly extracted folder 'Reset-Grub' and type one at a time: sudo cp -R desktop-base /usr/share/images/ sudo cp grub-logo.png /usr/share/icons/ sudo cp Reset-Grub.desktop /usr/share/applications/ sudo cp reset-grub /usr/bin/ sudo chmod a+x /usr/bin/reset-grub
The app: Reset-Grub will appear in Menu > System Tools > AdministrationLast changelog:
Suggestion
A suggestion to the user: On installed system in /boot/grub/grub.cfg Changed lines 121 to 132 or whatever it is in your file, the section that is enclosed in 05_debian_theme, to: ...... ...... ### BEGIN /etc/grub.d/05_debian_theme ### set menu_color_highlight=yellow/blue insmod png background_image -m stretch /boot/grub.png if background_image /boot/grub.png; then true else set menu_color_normal=white/black set menu_color_highlight=black/light-gray fi ### END /etc/grub.d/05_debian_theme ### ...... ......
This will show the background image grub.png 640 x 480 px placed in folder: /boot/ The highlighted line has yellow text on blue highlight bg The background for the other lines is transparent
