Grub-Customizer on Slackware 14

slackd · 06-29-2013, 02:48 AM

As the title suggests. I use grub on my laptop. Being spoilt by the grub-customizer package in ubuntu, I wanted the same in Slackware.

I have made the SlackBuild and made the package and it took a lot of effort.
Major Props to Erics AST tool.

It has installed fine, but when i started it, i ran into a problem. The /etc/defaults/grub file in the grub2 slackbuild package was spitting out a "sed" error. so i had to customize the file a little bit.

Edit as follows (in line 8):

From ->

Code:

GRUB_DISTRIBUTOR="$( sed s/Slackware /Slackware-/ /etc/slackware-version )"

To ->

Code:

GRUB_DISTRIBUTOR="$( cat /etc/slackware-version 2>/dev/null || echo Slackware )"

Now run Grub-customizer!

I am uploading the package as well as the source/slackbuild .xz file. In case anyone is interested in trying it out.
If it works properly, I will think about posting it to slackbuilds.org.

here is a sample of my /etc/defaults/grub file, if anyone wants to have a look.

Code:

# If you change this file, run grub-mkconfig -o /boot/grub/grub.cfg
# afterwards to update /boot/grub/grub.cfg.

GRUB_DEFAULT="2"
#GRUB_HIDDEN_TIMEOUT="0"
GRUB_HIDDEN_TIMEOUT_QUIET="false"
GRUB_TIMEOUT="15"
GRUB_DISTRIBUTOR="$( cat /etc/slackware-version 2>/dev/null || echo Slackware )"
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL="console"

# 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_VIDEO_BACKEND="vbe"
GRUB_GFXMODE="1366x768x24"
GRUB_GFXPAYLOAD_LINUX="1366x768x24"
GRUB_TERMINAL_OUTPUT="gfxterm"

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID="true"

# Uncomment to disable generation of recovery mode menu entrys
#GRUB_DISABLE_LINUX_RECOVERY="true"

GRUB_SAVEDEFAULT="false"

GRUB_BACKGROUND="/boot/slackware.jpg"

export GRUB_COLOR_NORMAL="white/black"
export GRUB_COLOR_HIGHLIGHT="red/black"

If you want to build the the Package, you will need the following extra dependencies:

1. GTKMM

Go Ahead:

Source>
Package>

Hope I am not forgetting anything :P

Good Luck, Do report back!

Hi there,

sorry I can't help you on that one, but I just try to hang on with my own incomprehension.

What do you mean by "spoilt"? Does it work for you in Ubuntu? - I use Mint for the most part (Mint 12 and 13), which is supposed to be Ubuntu-like, and I'm being fooled by grub-customizer.

Well, I can tune the settings the way I like, and obviously they get stored somewhere, because when I run grub-customizer again at a later time, I see my previous settings again. But they're not reflected by the actual GRUB behavior.

Whether I play around with video resolution, colors, or the GRUB wallpaper, or even the items I wish to be displayed or omitted from the GRUB menu, all that has no effect on the two PCs I used to try grub-customizer. So wherever that program stores its settings - it's not GRUB's configuration file /etc/default/grub.

Maybe grub-customizer only works with GRUB legacy?

@Doc CPU: Changing options in /etc/default/grub will not change the behavior of Grub unless you notify Grub of the changes with

Code:

sudo update-grub

I would think that a program that is meant to customize Grub does this automatically, but maybe it does not.

The point is that /etc/default/grub remained totally unaffected when I tried to get somewhere with grub-customizer. Neither the file contents nor its timestamp was changed. And yes, of course grub-customizer was executed with root privileges, so it should be able to write to the config file. Obviously it saved its settings somewhere else.

Editing the grub config file manually and issuing "update-grub" after that works fine, and always has.

@Doc CPU

Sorry about the late reply but I was working on a project presentation for my summer internship

Seems like your question has been partly been answered, but to clarify your second question. Grub Customizer stores its settings in /etc/grub.d/*_*_proxy files.. see the following >

Code:

[02:50:59] root@SamBox:~ # ls -l /etc/grub.d/                
total 76
-rwxr-xr-x 1 root root  7617 Jun 28 05:03 00_header

drwxr-xr-x 2 root root  4096 Jun 30 15:44 bin
drwxr-xr-x 2 root root  4096 Jun 30 15:44 proxifiedScripts

Any changes you make in the /etc/default/grub file also remains true and is applied when you run

Code:

update-grub

.

Hope this Clarifies your doubts!

See the contents of one those files, just to make things clear!
