I am planning to customize Ubuntu 13.04 live cd. How is it possible to customize Ubuntu live cd plymouth theme in ubuntu 13.04 ?
Is it possible to replace the pink purple colour of Ubuntu's default plymouth theme with an image?
I am using ubuntu-builder_2.4.1-gb3-1_all.deb Version 2.4.1 Debian package (Gambas 3) in my host machine which runs Ubuntu 13.04. I am using the same version 64-bit iso to customize it using the ubuntu-builder.gambas. Everything works fine, and I created the iso file. But when I run it in qemu or virtualbox, it shows a popup message box saying /casper/vmlinuz.efi: file not found. The screenshot shown below is from VirtualBox:
In the casper directory of the iso made by the builder there is no file named vmlinuz.efi
I recently updated 13.04, and upgraded the kernel. After that, the software center seems not to be working. when I click on the icon, the logo just blinks and nothing happens. Is it possible to correct this, or how do I remove the software center.
When I issue the command
sudo apt-get remove software-center
it, asks to remove ubuntu-desktop too. What is ubuntu-desktop, and is it very important for the system ?
I am not a noob to Ubuntu. I have been here for a while. The question I am going to ask is basically requiring an explanatory answer, possible with examples. My question is simple. It is as below:-
Everyone says, Ubuntu was developed from Debian, by tripping down so many thing, adding something else, giving custom displays, branding, images or backgrounds, etc. My question is how do they do it. Was it by just installing a minimal Debian distro in a computer system, adding and making changes to that system, adding Ubiquity installer to the installed distro, and then creating an iso file ?
Consider the two scenarios.
Scenario 1
They mount a CD ISO image
Remove unwanted packages
Add branding
Make customizations
repack the ISO
-OR-
Scenario 2
Install a Debian distro in the PC
Remove unwanted packages, and install new ones to the installed OS
Apply custom brandings to the installed OS
Make customizations in the installed machine
Add an installer to the installed OS
repack the ISO
What is actually happening ?

I have a few question related to customizng Ubuntu 12.04 Live CD using the tutorial given at https://help.ubuntu.com/community/LiveCDCustomization .
For me it was possible to modify till the section where we install new softwares ( section 6.1.2) to the live cd. After that I directly jump to Advanced Customization (section 6.7) located at https://help.ubuntu.com/community/LiveCDCustomization#Advanced_Customizations . My questions are:-
1) When I run the following command to mount the live cd, it shows a warning that the iso is mounted as read only. Is it ok, or should it be writable?
2) There are three folders created in the folder livecdtmp. They are edit, extract-cd and mnt. My questions are, which folder should I edit so that the change happens to the "customized live cd", and which folder to edit to have the customized Ubuntu installation ?
3) What is the use of extract-cd, edit and mnt folders ?
4) The tutorial says, to have a custom background for GNOME, I have to edit /usr/share/gnome-background-properties/ubuntu-wallpapers.xml . Which file, or the file in which folder should I edit for the change to happen both in Live cd and the customized installation.
5) Then, coming to the Advanced Customiation --> Kernel Updation, once inside the chroot, I cannot issue the following commands :-
sudo cp edit/boot/vmlinuz-2.6.15-26-k7 extract-cd/casper/vmlinuz
sudo cp edit/boot/initrd.img-2.6.15-26-k7 extract-cd/casper/initrd.lz
It says, folder dosn't exist. Should this be done from inside the chroot environment ?
6) The tutorial says that, in order to edit the inird.lz file, I have to perform the following steps.
# cd extract-cd/casper
# mkdir lztempdir
# cd lztempdir
# lzma -dc -S .lz ../initrd.lz | cpio -imvd --no-absolute-filenames
Should this be done in chroot environment that we initially prepared ? Does editing this file alone make changes to both the customized live cd as well as to the installation made from that live cd ?
When I run the last command, I get the error, that there is a premature end of archive, or no file found ?
From the # symbol, it means that I should run it within the chroot environment. But the problem is that, whenever I run the command cd extract-cd/casper , it says, there is no such directory which is actually true, because, what is mounted is the 'edit' folder. So, what should be done ?
7) There are initrd.lz file in /casper folder in both 'extracr-cd' and 'mnt'. Should I copy the Kernel file to both these folders? Which one should I need to edit inorder to have updated kernel, new plymouth theme, etc ?
8) I wish to set gnome-classic to have in the live cd? What should be done in order to have the gnome-classic in both the live cd and in the installation made with that cd ?

Update:- When I ran the following command outside chroot, I get the following error.
roshan@roshan-Studio-1558:~/initrd$ lzma -dc -S .lz ../livecdtmp/extract-cd/casper/initrd.lz | cpio -imvd --no-absolute-filenames
lzma: ../livecdtmp/extract-cd/casper/initrd.lz: File format not recognized
cpio: premature end of archive
I am using Ubuntu 11.10 ( I reverted back from 12.04 to 11.10 because of stability issues). I would like to know is it possible to change the location of the password field in the login screen ?
I am facing these weird problems after updating Ubuntu 12.04 with apt-get update && apt-get upgrade:
It takes too much time to come to the Plymouth theme after selecting Ubuntu from the grub menu. Is it possible to correct this?
On the login screen, before entering the password, whenever I move the mouse, it is kind of lagging/stuck. Only after entering the password and pressing Enter, it works normally.
I think this may be because of the updated kernel.
If so, is it possible to downgrade the kernel to the previous one ? If that is not the reason, what can be the problem?
I am making a custom distribution, and have a question about the Ubuntu Logo with 5 dots displayed when booting up.
The Ubuntu-Logo-Script in the /lib/plymouth/themes/ubuntutext folder has the word Ubuntu and beneath that 5 progressing 'dots'. Is it possible to remove the progress bar dots, and instead replace it with a faded Ubuntu logo, that gradually colors up to full?
I am using Ubuntu 12.04 as host, and I plan to compile a new kernel. I downloaded the Linux-Libre kernel. When compiling the kernel, I would like to "Load alternate configuration".

I would like to build a custom Ubuntu from the minimal Ubuntu version. I plan to use the 11.10 version.
