Custom Build Chromuium browser: Black Screen & Reboot After Login

[Vishwa Kalubowila]

Hi Everyone,

I'm running into a persistent issue when testing a custom Chromium browser build. My setup involves deploying the custom browser to a device booted from a USB test image via a reverse SSH tunnel.

The device boots correctly from the USB and I can get to the login screen without any problems. However, the moment I successfully log in, this exact sequence happens:

1. The screen immediately goes black.
2. The device reboots.
3. It loops back to the developer mode recovery UI instead of restarting the OS.

Has anyone encountered this specific "login -> black screen -> reboot to recovery" loop before? I'm trying to figure out if this is a known graphics initialization issue or something else entirely.

Any guidance on which logs would be most useful for diagnosing a crash at this specific point would be greatly appreciated.

Thanks for any help
