Install Theme
I have created theme as you wanted with faded ubuntu ( moreover I have added animation of ubuntu logo. Hope you'd like it :-P )
Screenshot
Want to see it live ?
Go to http://www.youtube.com/watch?v=zPo50gM3txU
Where to Get this theme ?
I have uploaded it to Mediafire cloud HERE
How to install it ?
Download from the above link and save it on your Desktop then issue these commands one by one.
cd ~/Desktop/
tar -xf ubuntufaded.tar
sudo cp -r ubuntu-faded-screen '/lib/plymouth/themes'
sudo rm '/lib/plymouth/themes/default.plymouth'
sudo ln -s '/lib/plymouth/themes/ubuntu-faded-screen/ubuntu-faded-screen.plymouth' '/lib/plymouth/themes/default.plymouth'
sudo update-initramfs -u
How to check it ?
- Restart Ubuntu and you'll see nice animation while booting up and
shutting down. OR
Copy the whole command, Paste in terminal and Hit enter.(probably you need to install package. sudo apt-get install plymouth-x11 )
sudo plymouthd --debug --debug-file=/tmp/plymouth-debug-out ; sudo plymouth --show-splash ; for ((I=0;I<10;I++)); do sleep 1 ; sudo plymouth --update=event$I ; done ; sudo plymouth --quit
How to Create Plymouth Theme yourself ?
Plymouth Scripting Language is very similar to C or JavaScript. If you know these languages, it'll be very easy to create Plymouth Script yourself.
Let's Start with Basics like Operators, Looping, Comments, etc.
Three type of comments are supported.
# comment like in bash
// single line comment like in C
/* block comments */
Statements are terminated with Semicolon, e.g.
foo = 10 ;
Statement block can be created with Curly Brackets, e.g.
{
foo = 10;
z = foo + foo;
}
Operators supported are +, -, *, /, %.
Shorthand is also supported +=, -=, *=, etc.
Unary Operators are also supported, e.g.
foo *= ++z;
+ is used for Concatination e.g.
foo = "Jun" + 7; # here foo is "Jun7"
Comparison exmple,
x = (3 >= 1); # bind x to 1 because it's true
y = ("foo" == "bar"); # bind y to 0 because it's false
Conditional Operations and Looping,
if ( foo > 4 )
{
foo--;
z = 1;
}
else
z = 0;
while (foo--)
z *= foo;
&&, ||, ! are also supported
if ( foo > 0 && foo <4 )
Probably something new, Hashes Similar to Array ?
Hashes can be created by accessing their contents using dot or [ ] brackets, e.g.
foo.a = 5;
x = foo["a"] ; # x equals to 5
Use fun Keyword to define function, e.g.
fun animator ( param1, param2, param3 )
{
if ( param1 == param2)
return param2;
else
return param3;
}
There are Basic Two Plymouth Objects
ImageSprite
Image
To create new Image, Give filename of image within theme directory to Image().
Remember, Only .png files are supported, e.g.
background = Image ("black.png");
To show text message you must create Image of Text (Surprised ??), e.g.
text_message_image = Image.Text ("I love Ubuntu");
Width and Height can be known using GetWidth() and GetHeight(), e.g.
image_area = background.GetWidth() * background.GetHeight();
Rotate or Change size of Image, e.g.
down_image = logo_image.Rotate (3.1415); # Image can be Rotated. Parameter to Rotate is the angle in radians
fat_image = background.Scale ( background.GetWidth() * 4 , background.GetHeight () ) # make the image four times the width
Sprite
Use Sprite to place Image on screen.
How to create Sprite ?
first_sprite = Sprite ();
first_sprite.SetImage (background);
Or by supplying image to its constructor,
first_sprite = Sprite (background);
How to Set different Positions on screen (x,y,z) ?
first_sprite.SetX (300); # put at x=300
first_sprite.SetY (200); # put at y=200
background.SetZ(-20);
foreground.SetZ(50);
Or you can define with SetPosition()
first_sprite.Setposition(300, 200, 50) # put at x=300, y=200, z=50
How to change Opacity ?
faded_sprite.SetOpacity (0.3);
invisible_sprite.SetOpacity (0);
Different Methods Used are
Window.GetWidth();
Window.GetHeight();
Window.SetBackgroundTopColor (0.5, 0, 0); # RGB values between 0 to 1.
Window.SetBackgroundBottomColor (0.4, 0.3, 0.6);
Plymouth.GetMode(); # returns a string of one of: "boot", "shutdown", "suspend", "resume" or unknown.
etc.
Predefined Functions
Plymouth.SetRefreshFunction (function); # Calling Plymouth.SetRefreshFunction with a function will set that function to be called up to 50 times every second
Plymouth.SetBootProgressFunction(); # function is called with two numbers, time spent booting so far and the progress (between 0 and 1)
Plymouth.SetRootMountedFunction(); # function is called when a new root is mounted
Plymouth.SetKeyboardInputFunction(); # function is called with a string containing a new character entered on the keyboard
Plymouth.SetUpdateStatusFunction(); # function is called with the new boot status string
Plymouth.SetDisplayPasswordFunction(); # function is called when the display should display a password dialogue. First param is prompt string, the second is the number of bullets.
Plymouth.SetDisplayQuestionFunction(); # function is called when the display should display a question dialogue. First param is prompt string, the second is the entry contents.
Plymouth.SetDisplayNormalFunction(); # function is called when the display should return to normal
Plymouth.SetMessageFunction(); # function is called when new message should be displayed. First arg is message to display.
Mathematical Functions
Math.Abs()
Math.Min()
Math.Pi()
Math.Cos()
Math.Random()
Math.Int()
etc.
Your Better bet to create Plymouth Script is to modify existing one rather than starting from scratch
Open up .script file from my uploaded theme and try to understand what it does.
Fantastic Guide here
I'm sure you'll learn this. It isn't hard. Let me know if you need any Help.
Hope it'd help you create One yourself.
