Capture screenshot of HDMI output

I'm trying to use fbgrab to take a screenshot of the HDMI output using:

fbgrab -d /dev/fb0 screenshot5.png

But I'm just getting the terminal. Am I asking for the wrong device, or is it simply not possible?

Sensu and other monitoring solutions

I have several raspberries up running, and currently they're telling me what they're up to by sending e-mails. The solution isn't excellent, hence I'm looking for a good way of monitoring the whole thing. I found Sensu, which seems to do exactly what I'm looking for. 1. Has anyone tried Sensu using ...

Re: How often does the Pi (Rasbian) update it's clock?

You make it sound like there's nothing strange going on here. Am I missing something obvious here? Is there a good reason to why the system isn't configured to invoce ntpd with the -g option after the Internet has been down for a while? The ntpd daemon is running all the time, so it won't be invoke...

Re: How often does the Pi (Rasbian) update it's clock?

Check out the "-g" option (to ntpd). The "-g" option is already set. It only works once per invocation. ie. at startup. Restarting ntpd once the network is available again will set the clock correctly: sudo /etc/init.d/ntp restart You make it sound like there's nothing strange g...

Re: How often does the Pi (Rasbian) update it's clock?

If the time is more than a few minutes out when ntpd starts, it will set the time directly. After that it will only speed up or slow down the system clock slightly until the time is correct. If the Pi was without internet, but still running, for 48 hours, I'd expect the system clock to drift a bit,...

Re: How often does the Pi (Rasbian) update it's clock?

Very strange… So the 36 minute offset must have been due to faulty servers or Internet being down without the Pi being down? Yeah, it is pretty clear that's the real issue/point of this thread. The OP says that the Pi was disconnected from the Interwebs "for a while" - and that during tha...

How often does the Pi (Rasbian) update it's clock?

I know the Raspberry doesn't have a real clock inside, but uses NTP servers to keep track of time. It works well, but mine suddenly got an offset of 38 minutes (so it wasn't a matter of time zones). I know it had been standing without an Internet connection for a while, I don't know if that had anyt...

The root, it seems. Would this explain why I can see the boot partition when I put the SD card into my Linux laptop, but when I try to mount the root file system I get an error and can't mount it.
