I don't have a setup with an LVDS-VGA adapter board to test, but my guess would be that even if we pick a mode the panel can do we'll pick a clock rate that it cannot. > I think my setup is correct, because the vesa frambuffer seems to work > correctly.

What mode is the vesa driver using and if you set the same mode what happens ? > [ 110.197942] ioremap error for 0x7f7f8000-0x7f7fb000, requested 0x10, got 0x0 That is expected > [ 110.206418] [drm:drm_mode_debug_printmodeline], Modeline 0:"1280x1024" 0 108000 1280 1328 1440 1688 1024 1025 1028 1072 0x8 0x0 So we picked 1280x1024 > [ 110.257714] [drm:drm_sysfs_connector_add], adding "LVDS-1" to sysfs > [ 110.257932] [drm:drm_sysfs_hotplug_event], generating hotplug event > [ 110.269604] [drm:psb_intel_sdvo_read_byte], i2c transfer returned -6 > [ 110.269633] [drm:psb_intel_sdvo_init], No SDVO device found on SDVOB We found the LVDS, we found nothing on the SDVO > [ 110.561304] [drm:drm_helper_probe_single_connector_modes], [CONNECTOR:7:LVDS-1] > [ 110.586242] [drm:drm_helper_probe_single_connector_modes], [CONNECTOR:7:LVDS-1] probed modes : > [ 110.586274] [drm:drm_mode_debug_printmodeline], Modeline 10:"1280x1024" 40 71500 1280 1328 1440 1688 1024 1025 1028 1072 0x8 0x0 And we probed a 1280x1024 mode with a clock of 71.5 (which might be a bit high for the panel ?) > [ 110.637467] [drm:drm_crtc_helper_set_config], crtc has no fb, full mode set > [ 110.637484] [drm:drm_crtc_helper_set_config], modes are different, full mode set We didn't have a mode before, we have one now. > [ 110.637500] [drm:drm_mode_debug_printmodeline], Modeline 0:"" 0 0 0 0 0 0 0 0 0 0 0x0 0x0 > [ 110.637529] [drm:drm_mode_debug_printmodeline], Modeline 11:"1280x1024" 40 71500 1280 1328 1440 1688 1024 1025 1028 1072 0x8 0x0 > [ 110.637564] [drm:drm_crtc_helper_set_config], encoder changed, full mode switch > [ 110.637580] [drm:drm_crtc_helper_set_config], crtc changed, full mode switch > [ 110.637599] [drm:drm_crtc_helper_set_config], [CONNECTOR:7:LVDS-1] to [CRTC:4] Do a full load > [ 110.637618] [drm:drm_crtc_helper_set_config], attempting to set mode from userspace > [ 110.637634] [drm:drm_mode_debug_printmodeline], Modeline 11:"1280x1024" 40 71500 1280 1328 1440 1688 1024 1025 1028 1072 0x8 0x0 > [ 110.637678] [drm:drm_crtc_helper_set_mode], [CRTC:4] > [ 110.658501] [drm:drm_mode_debug_printmodeline], Modeline 11:"1280x1024" 40 71500 1280 1328 1440 1688 1024 1025 1028 1072 0x8 0x0 > [ 110.699109] [drm:drm_crtc_helper_set_mode], [ENCODER:8:LVDS-8] set [MODE:11:1280x1024] > [ 110.977395] [drm:drm_calc_timestamping_constants], crtc 4: hwmode: htotal 1688, vtotal 1072, vdisplay 1024 > [ 110.977415] [drm:drm_calc_timestamping_constants], crtc 4: clock 71500 kHz framedur 25307776 linedur 23608, pixeldur 13 We set it all up and seem happy. > [ 110.977439] [drm:drm_crtc_helper_set_config], Setting connector DPMS state to on > [ 110.977453] [drm:drm_crtc_helper_set_config], [CONNECTOR:7:LVDS-1] set DPMS on > [ 111.032366] Console: switching to colour frame buffer device 160x64 > [ 111.064932] fb0: psbfb frame buffer device > [ 111.064944] drm: registered panic notifier > [ 111.066827] gma500 0000:00:02.0: Backlight lvds set brightness 7a120000 > [ 111.066860] [drm] Initialized gma500 1.0.0 2011-06-06 for 0000:00:02.0 on minor 0 Do you have a different monitor around to try and also hand setting lower modes ? _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
