Tx2-4g r32.3.1 multi-user.target not working

My custom board with mipi-dsi display works great if in graphical.target mode. Changed to multi-user.target and am not getting any prompt on my display.

Also tried to do a ctl-alt-f4 in graphical.target mode and got no prompt, so appears to be a mipi-dsi problem, anyone else seen/fixed

am I missing something in the driver to make multi-user.target happy?

the backlight is on, so the display should work, but I think the smoking gun is the ctl-alt-f4 not working in graphical.target


More information.

When I do the ctl-alt-f4 dmesg shows.

Everything gets disabled/blanked, powerdown, nothing is working so of course nothing is displayed.

When I do ctl-alt-f1 dmesg shows.

Things go down but are brought back up,

Real question does ctl-alt-f4 work on normal Nvidia hdmi systems?


So far as I know the text consoles do work when using a CTRL-ALT-F#. There have been issues with forcing purely text mode, especially in earlier releases. This URL is probably of use:
