I am attempting to port my display settings from WEC7/8 to Angstrom LXDE 2.8b7 (previous .reg settings are attached below). I can view the OS on a DVI connection to a monitor, but when I plug into our touch screen I do not get any video output. Just the backlight is visible. I have looked over the following support posts to see if I could resolve this issue myself:
- Apalis T30 HDMI Supported Resolutions (1920x540?) - Technical Support - Toradex Community
- Set lvds display to single channel at booting stage - Technical Support - Toradex Community
As I understand it, 1024x600 is not an EDID supported resolution so updating boot environment variables will not help me. I attempted to update tegra30-apalis.dts(seen below) and recompile/deploy the new boot image, but that did not help either.
Is there anything that I am missing?
