I have XBMCbuntu systems which have only a remote control connected (no keyboard, no mouse)
If the systems are rebooted using the PC's physical power button, they get stuck at a GRUB boot screen !
This is really stupid default behavior!
- It only happens if you do not have a keyboard connected
- It can only be resolved using a keyboard
- no timeout, it just sits there
- In my case (2 different PCs with different remotes) it can only be resolved by plugging in a keyboard and rebooting with the same PC power button
Anyhow it's not hard to fix if this is something that affects you:
Edit 3 lines in /etc/default/grub
Then rebuild grub with this command: sudo update-grub
As far as I can tell my systems are now fool proof and family can't break them.
