Linux logo and screen cursor

Logo and screen cursor
By default, the Linux boot logo is generally 8080808080's penguin icon. Sometimes, for some effect, we hope
During startup, the User-Defined logo is displayed in full screen, which requires a new logo for Linux.

 

Prepare PNG Images

Use any image software to create a custom boot image, which can be set according to the size of your own LCD, PNG
Format. Take the 224 color as an example.

I used a PNG Image of jylogo800133.

 

Convert to a PPM File

# Pngtopnm jylogo800480.png | ppmquant-Fs 223 | pnmtoplainpnm>
Logo_jylogo_clut224.ppm

 

Add new logo

Copy the obtained ogo_jylogo_clut224.ppm file to the drivers/Video/logo directory and name it
Logo_jylogo_clut224.ppm

Drivers/Video/logo/logo_jylogo_clut224.ppm

 

 

Go to the drivers/Video/logo directory and modify the logo. c file:

 

Extern const struct linux_logo logo_jylogo_clut.pdf;

 

And add:

# Ifdef config_logo_jy

Logo = & logo_jylogo_clut.pdf;

Return logo;

# Endif

 

Modify makefile:

OBJ-$ (config_logo_jy) + = logo_jylogo_clut224.o

 

 

Modify the kconfig file:

Config logo_jy

Bool "JY-01 Linux logo"

Default y

 

The red flag must be the same and follow the naming method (logo_yourname_type.

 

Disable the LCD console cursor

In addition, after a full screen logo image is used, the console still has a blinking cursor. How can this problem be disabled?

Removed framebuffer console support. Try again.

No. No logo is displayed.

 

Drivers/Video/console/makefile

# Obj-$ (config_framebuffer_console) + = fbcon. O bitblit. O font. O softcursor. o

OBJ-$ (config_framebuffer_console) + = fbcon. O bitblit. O font. o

 

Compilation encountered a problem that soft_cursor was not defined. Note the Code:

Drivers/Video/console/bitbw.c

// If (ERR)

// Soft_cursor (Info, & cursor );

 

The cursor is disabled, and the graphic interface starts normally.
