I just downloaded Kodi and we all know about the screen going blank.. well I got it off the blank screen but there are 8 (visible) task managers open. The mouse still moves, so it isn't completely frozen, but might as well be. What is the safest way to shutdown my pi? I cannot get into terminal. Is there by any small chance a hotkey for this?
Thank you so much for your help!
Joshua.

Re: How to safely shutdown raspberry pi when its frozen
Its unsafe to power down when there is (or recently has been) write action to the SD-card going on.
If recent writes have occurred the SD-card might decide to do some household tasks which when interrupted may lead to corruption. Otherwise it should be safe to power off, only the power off will cause a "dirty" bit set in the filing system, but that should not be a disaster.
Watch the ACT LED, as long as its blinking the sd-card is active then powering down is inadvisable.
If there is no SD-card action, then wait a few seconds and power off.
The is no "shortcut" key-combination to power down AFAIK.

Apart from the "magic sysrq" keys.mahjongg wrote: The is no "shortcut" key-combination to power down AFAIK.
[CTRL]+[ALT]+[SYSRQ] then [R] for reboot.
[CTRL]+[ALT]+[SYSRQ] then [O] for poweroff.
Any language using left-hand whitespace for syntax is ridiculous

Yup, there is, but it's pretty old-school Linux.mahjongg wrote:...The is no "shortcut" key-combination to power down AFAIK.
Hold down both Alt+PrintScreen, and while holding those keys, hit the following keys in sequence, one at a time, with a few seconds pause between them.
R E I S U B
A handy mnemonic to remember that is, Reboot Even If System Utterly Broken.
Substitute "O" for "B" to shutdown the system instead of rebooting (O=off, B=boot).
