I am currently in a program on the PI and can't access terminal or see my button in my gui to safely exit the program. I treid evrythin in task manager, which does nothing.
For some reason I didn't get full resolution on my display so the full Gui isn't there.
I've learned the hard way not to power down and here I am stuck with the same damn problem. Is there maybe some fancy keyboard combination I can use or something? -- don't know why task manager isn't helping.
Re: Safe shutdown
I suppose (possibly) I could take out the SD card (while the pi is on) and then power off?
Re: Safe shutdown
I did that, removed the card -- tried to delete this post -- can't do it ??
Re: Safe shutdown
I'm not sure that pulling the card from a running Pi is any smarter than powering down.

Re: Safe shutdown
If you can get to the system with a command prompt, you can stop a program by killing it's process ID. One way to find the PID is to use the command "ps -C <progname>", followed by "kill <PID>". if your program ignores interrupts and refuses to die, you can use "kill -9 <PID>" (aka "sure kill").
IF all you want to do is shut the system down without access to it (either GUI or ssh), wait until there is no activity for several seconds (to allow any wear leveling to complete), then pull the power. I definitely would not recommend removing a working SD card.
