how do i run this repo about lv_port_linux

[kisvegabor]

Just change the frame buffer device here and build it with make.

[qNnOtTk]

i compiled it, running ./demo gives me this error

rock@radxa-zero:~/lv_port_linux_frame_buffer$ sudo ./demo
ioctl(FBIOBLANK): Invalid argument

I also tried running DISPLAY=:0 ./demo but still not working

update:
i got it working without any error messages, removing line 97-101 seems to have fixed the problem, but all i can see on fb1 is some off white color, and black lines next to it

[kisvegabor]

I also wanted to suggested to remove the FBIOBLANK line. 🙂

Please send a screen shot.

@qNnOtTk you can't just run it on your host ! it's probably running X11 or Wyland, try it on a target with framebuffer

[symfund]

To run this repo, your linux kernel must support frame buffer driver or DRM/KMS driver with legacy fbdev support. Also this repo can run in Wayland environment with or without X11!

Hi sorry i forgot about this issue i made, anyway, i figured out how to run it on X11, i just hid the cursor and ran it on fullscreen and its good enough for me, thanks for the help
