bootconf [options...]



is a small utility that provides a convenient way to set or inspect some common Linux kernel boot options. bootconf updates the GRUB configuration file (/boot/grub/grub.conf in most cases). The changes will take effect, naturally, at the next reboot.

The following parameters may be specified:


This parameter must be specified by itself, alone. bootconf displays a formatted list of available boot partitions and kernels.


The default boot kernel or partition is lqnrq, where lqnrq is the boot partition number from the list produced by the -titles parameter.

quiet or quiet=1

Suppress most diagnostic messages when the Linux kernel initializes.

noquiet or quiet=0

Display diagnostic messages when the Linux kernel initializes.

gui or gui=1

Show the status of the system boot process graphically (the lqrhgbrq boot option).

nogui or gui=0

Show the status of the system boot process as text.


Use a VESA framebuffer for the system display (see below).


Do not use the VESA framebuffer for the system display.

Running bootconf without specifying any parameters displays the current settings. Run bootconf from X to show a small window where the individual settings can be adjusted graphically.

The current settings are parsed from the first kernel listed in GRUB's configuration file, but new settings are saved for every configured kernel.

VESA framebuffer

Many modern video cards are capable of providing a standard, vendor-independent access mechanism to the display memory. Linux can use this framebuffer for the system console, as opposed to the traditional text display.

The lqvesa=moderq option configures the Linux kernel to set the video card framebuffer to mode. The possible values for mode are:

640x480x8 640x480x15 640x480x16 640x480x24 800x600x8 800x600x15 800x600x16 800x600x24 1024x768x8 1024x768x15 1024x768x16 1024x768x24 1280x1024x8 1280x1024x15 1280x1024x16 1280x1024x24 1600x1200x8 1600x1200x15 1600x1200x16 1600x1200x24


Your video card may not support all of the above video modes. Check your video card's documentation. If you select an invalid video mode, the Linux kernel may not be able to boot. When that happens, press E to edit the kernel command line, in GRUB, remove the lqvga=NNNrq parameter, press Enter then B to boot without the framebuffer.
