How remove mouse cursor from my application?
Please try the following :
"Removing the Cursor of LCD framebuffer"
thanks but i'm on LVDS display...
Infact it not work!
Hi Giuseppe Ventura,
I want to remove the cursor in the LCD.
For this, I found some reference.
I could perform the unblinking cursor and the hidden cursor.
- cursor unblink
~ $ echo 0 > /sys/class/graphics/fbcon/cursor_blink
- cursor hide
~ $ echo -e '\033[?17;0;0c' > /dev/tty1
But I couldn't remove the cursor.
I could see the black cursor position not to be removed.
In other words, I could see the black cursor (not blinking) when I performed the upper command on the white displayed image of LCD.
Could you tell me how to remove the cursor?
And Yuri Muhin,
I could not find the reference site, "Removing the Cursor of LCD framebuffer".
Could you give me the correct address for that?
The Linux framebuffer starts with a cursor on screen, to hides this cursor you can use this command:
echo -e -n '\033[?25l' > /dev/tty0
Dear Yuri Muhin,
Thanks for your response.
This command hides the cursor,
but the previous cursor leave a trace with black mark.
I want to remove the black cursor mark.
Could you tell me the method?
I solved the problem.
For this, I modified the followed files in i.MX25.
(refer to "// Eric" comments in the files)
- No use Cursor Blink
. drivers/video/console/fbcon.c .
- No display 1st Cursor
How are you? Nice to see you in the forum.

Lines that we are looking out for interfacing are(LCDC_LD0 to LCDC_LD7) from UF/IF connector(from NVCC_LCDC moudule of i.mx25) and also have no idea how enable them from software.In the existing kernel image we too have fb0 and fb1 devices under /dev diretory. if any sample code is aviable please share some link or please direct me to correct way.
