> If someone knows how to fix the backlight, it would still be useful. In panel-dsi-cm.c it's set to maximum with dsicm_dcs_write_1(ddata, DCS_BRIGHTNESS, 0xff); Sebastian suggested the same but used 100 instead of 0xff, which might be a bit too low. You can also add msleep(1000) after dsicm_dcs_write_0(ddata, MIPI_DCS_SET_DISPLAY_ON); to see if brightness gets overwritten, the whole display goes into sleep mode, is turned off or similar somewhere down the line. I'm still unable to make N9 panel to cooperate (despite having "the right" clocks and able to send image to panel with MIPI_DCS_WRITE_MEMORY_START/MIPI_DCS_READ_MEMORY_CONTINUE) so I hope you'll have more luck than me!
