I've updated the trace with increased log_buf_len so nothing is truncated: http://floe.butterbrot.org/external/radeon/dmesg_after_suspend.txt (trace now contains a full boot including suspend and wakeup) However, what I'm seeing now does sound like the internal connection is indeed eDP: [ 166.816162] [drm:drm_mode_setcrtc] [CRTC:34:crtc-0] [ 166.816166] [drm:drm_mode_setcrtc] [CONNECTOR:40:eDP-1] [ 166.816167] [drm:drm_crtc_helper_set_config] [ 166.816169] [drm:drm_crtc_helper_set_config] [CRTC:34:crtc-0] [FB:54] #connectors=1 (x y) (0 0) [ 166.816170] [drm:drm_crtc_helper_set_config] crtc has no fb, full mode set [ 166.816172] [drm:drm_mode_object_reference] OBJ ID: 40 (4) [ 166.816173] [drm:drm_crtc_helper_set_config] encoder changed, full mode switch [ 166.816174] [drm:drm_crtc_helper_set_config] crtc changed, full mode switch [ 166.816174] [drm:drm_crtc_helper_set_config] [CONNECTOR:40:eDP-1] to [CRTC:34:crtc-0] [ 166.816175] [drm:drm_crtc_helper_set_config] attempting to set mode from userspace [ 166.816177] [drm:drm_mode_debug_printmodeline] Modeline 65:"" 0 241500 2560 2608 2640 2720 1440 1443 1448 1481 0x0 0x9 [ 166.816180] [drm:radeon_encoder_set_active_device] setting active device to 00000002 from 00000002 00000002 for encoder 3 [ 166.816183] [drm:radeon_get_monitor_bpc] eDP-1: Display bpc=8, returned bpc=8 [ 166.816185] [drm:drm_detect_monitor_audio] Monitor has basic audio support [ 166.816186] [drm:radeon_get_monitor_bpc] eDP-1: Display bpc=8, returned bpc=8 [ 166.816188] [drm:drm_detect_monitor_audio] Monitor has basic audio support [ 166.816192] [drm:drm_crtc_helper_set_mode] [CRTC:34:crtc-0] [ 166.816208] [drm:radeon_get_monitor_bpc] eDP-1: Display bpc=8, returned bpc=8 [ 166.816210] [drm:radeon_atom_encoder_dpms] encoder dpms 30 to mode 3, devices 00000008, active_devices 00000000 [ 166.816213] [drm:radeon_atom_encoder_dpms] encoder dpms 22 to mode 3, devices 00000010, active_devices 00000000 [ 166.816235] [drm:drm_detect_monitor_audio] Monitor has basic audio support [ 166.816237] [drm:radeon_compute_pll_avivo] 360000 - 360000, pll dividers - fb: 80.0 ref: 2, post 3 [ 166.824475] done. ... and a bit later: [ 166.853787] [drm:radeon_dp_link_train_cr] clock recovery at voltage 0 pre-emphasis 0 [ 166.853788] [drm:drm_detect_monitor_audio] Monitor has basic audio support [ 166.855953] [drm:radeon_dp_link_train_ce] channel eq at voltage 0 pre-emphasis 0 Best, Florian -- SENT FROM MY DEC VT50 TERMINAL
