Modify three images of ubuntu

I. usplash screen (BOOT/startup screen)
It is equivalent to Windows boot/boot screen, Because ubuntu 6.0.6 (dapper) uses the usplash software as the boot screen, so we call it a usplash screen.
Modifying this screen is the most difficult of the Three. If you use splashy, it will be much easier. The default boot screen here is/usr/lib/usplash/usplash-default.so, which is a compiled. So file, so it cannot be modified directly. For details about how to create a usplash image, see here. The following describes how to replace the usplash image in Ubuntu 6.0.6 (dapper.
1. Copy a prepared XXX. So file to your favorite directory, for example,/usr/local/usplash/xxx. So.
2. Then
Sudo Update-alternatives-install/usr/lib/usplash/usplash-artwork.so/usr/local/usplash/xxx. So 55
Sudo Update-alternatives-config usplash-artwork.so
Select the digit before XXX. So.
3. reconfigure the core
Sudo dpkg-reconfigure Linux-image-$ (uname-R)
4. Modify the usplash image resolution (as needed)
Sudo gedit/boot/GRUB/menu. lst
Find
Kernel/boot/vmlinuz-2.6.15-23-386 root =/dev/hdxx Ro quiet splash
Add VGA = 792 at the end
* VGA reference table
Depth -- 640 × 480 -- 800 × 600 -- 1024 × 768 -- 1280 × 1024
8bit ---- 769----771---773-----775
15bit ---- 784----787---790-----793
16bit ---- 785----788-----791-----794
24bit ---- 786----789-----792-----795

2. gnome Display Manager screen (logon screen)
The running of the running of a running on Running. It is part of gnome, so you can manage it in the system-system management-Logon window.
Just like adding a topic, click "add" to add a new logon screen and Preview It. It is said that after Ubuntu 6.0.6 is installed by default, the resolution here is set to the maximum resolution, and it looks like a flash. The modification method is as follows:
Sudo gedit/etc/X11/Xorg. conf
Find the last
Modes "1280 × 1024" "1152 × 864" "1024 × 768" "832 × 624" "800 × 600" "720 × 400" "640 × 480" "640 × 350 """
Put the resolution you need first, or delete unnecessary resolution. For example, if your monitor is a CTR of 17″, you can make it as follows:
Modes "1024 × 768" "1280 × 1024" "1152 × 864" "832 × 624" "800 × 600" "720 × 400" "640 × 480" "640 × 350 """

Iii. splash screens
This is the screen that displays the resource loading status after entering the user name and password. Windows does not have this screen, so we will call it to load the screen. It is simpler to replace with a PNG image. There are two ways to replace it.
1. The default address for this image is/usr/share/pixmpas/splash/ubuntu-splash.png.
It is linked to/usr/share/pixmpas/splash/ubuntu-slick.png on this image.
Replace ubuntu-slick.pngwith another file, and re-link ubuntu-splash.png to replace the image.
Example: Link/usr/local/xxx.png to/usr/share/pixmpas/splash/ubuntu-splash.png
Sudo ln-SF/usr/local/xxx.png/usr/share/pixmaps/splash/ubuntu-splash.png
2. You can also use the "configuration Editor" to modify its path.
Open "Application-System Tools-configuration Editor". By default, You must select it in alacarte menu editor to enable this option. You can also enter gconf-editor in the terminal to open it.
Find the branch of apps> gnome-session> options.
Change the splash_image address to the image address you want.
