16:33 jiaozhou_: <agd5f> Do you know where should I call this _atom_encoder_dpms(encoder, DRM_MODE_DPMS_OFF) function? I do not have access to encoder in many places of the code
16:44 agd5f: jiaozhou_, the encode is physically tied to the connector. You can look it up
20:28 jiaozhou_: <agd5f> I added if (ext_encoder)
20:28 jiaozhou_: radeon_atom_encoder_dpms(ext_encoder, DRM_MODE_DPMS_OFF); in radeon_atom_encoder_init function, but the screen resolution is still wrong
20:34 jiaozhou_: I am pretty sure I hit the line as I put a log there
21:11 agd5f: jiaozhou_, you don't need the ext_encoder check. Just call it unconditionally. e.g., https://paste.centos.org/view/1247b000
21:20 jiaozhou_: I added line there but the same resolution error happened
21:21 jiaozhou_: <agd5f>
21:26 agd5f: jiaozhou_, I dunno. Seems like some sort of board issue. I guess only a physical unplug or removal of power fixes it
21:27 jiaozhou_: yes, that is what happened
21:27 jiaozhou_: It fixed if I unplug the display port
