eglGetDisplay Return EGL_NO_DISPLAY

huabo bao

Hi expert,

I use a SOC with Mali-G78AE，I run a linux without desktop system.

When I use gbm_create_device to get gbm_device,I can get an non-null pointer. Then ,I use it to call eglGetDisplay,but I can get a EGL_NO_DISPLAY.

What is reason for error result ？Can you give me some suggestion？

The following is some log:

g_device_fd = 3
connector_id = 107,encoder_id = 106
resolution: 1920x720
gbm_device = 0x1cbab330
eglGetDisplay failed

    The behavior here depends on your driver's window system integration, and how that was done for your specific platform. 

    If you are direct Mali licensee please raise as support case, if you are an OEM I would suggest contacting your chip provider.

    Kind regards, 
    Pete
