#!/bin/bash # # h3disp # # Patches fex/script.bin settings to modify display settings. Currently # rather limited and only supporting HDMI and the available presets. # ############################################################################# # # Background informations: # # Only a certain amount of predefined video modes is available on H3 devices # as can be seen here: http://linux-sunxi.org/Fex_Guide#disp_init_configuration # # Purpose of this script is to display the available reasonable settings and # let the user choose from them to adjust fex file accordingly afterwards. # In the meantime it's also possible to specify available resolutions on the # command line. To display possible values use the -h switch. # # If HDMI-to-DVI adapters are used another fix has to be applied to the fex # file: http://linux-sunxi.org/Orange_Pi_One#HDMI_to_DVI_converters -- so ask # user whether he plans to use such an adapter and adjust fex file accordingly # ############################################################################# # # CHANGES: # # v0.2: Added non-interactive mode. You can provide one or two arguments on # the command line, eg. 'h3disp -m 1080p60 -d' (1920x1080@60Hz DVI) or # 'h3disp -m 720i' (1280x720@30Hz HDMI). Complete list of modes via # 'h3disp -h' # # v0.1: Initial release to adjust display settings in script.bin on commonly # used Debian based OS images for H3 devices running Linux. # ############################################################################# # # TODO: # # - implement real user interaction: dialog that asks which of the available # HDMI modes to choose and whether a HDMI-to-DVI converter is used or not # # - maybe implement live resolution switching as outlined by Jernej: # http://forum.armbian.com/index.php/topic/617-wip-orange-pi-one-support-for-the-upcoming-orange-pi-one/?p=5305 # (we would also need a working set of fbset modes in /etc/fb.modes # of course) # # - maybe add the chosen mode to /boot/boot.cmd and create /boot/boot.scr # afterwards? # ############################################################################# Main() { export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin # ensure script is running as root if [ "$(id -u)" != "0" ]; then echo "This script must be executed as root.
