Thanks for the tip on how to change the default menu to GUI mode.
I've had the same problem since upgrading to 6.2.3 (I think it was). I always upgrade to the latest version. I was hoping this would be fixed in subsequent versions, but no, it persists.
The biggest headache this caused was if I needed to reboot the system remotely it would never boot back up. It would just cycle around trying to boot into non-GUI mode (default), fail, then cycle again .. it was a pain.
At least now I can reboot into GUI mode remotely, but also select non-GUI mode when I'm local to the machine.
Thanks heaps.
UnRaid rocks!
