Do you see at least a window opened (even without content)?

我也遇到这个问题
I'm experiencing the same problem. I'm running on RPI4. I cloned lv_port_linux rep and built it as stated in its readme.md. I do sudo ./main inside bin folder but nothing shows up. Not even a window. I tried original main.c as well as some other lv_get_started functions inside the main loop but problem persists.
Do you have the UI (i.e. windows) of the Raspberry's OS running too? If so it overwrites what you draw into the frame buffer.
If this is the case press Ctrl + Alt + F1
to switch to command line mode and try running the LVGL app from there.
More info here. If it's working I'll update the README.
