What build number are you using?

Maguro isn't listed in the supported devices on the linked script"

SUPPORTED="mako manta grouper"

The fbgrab script from the fbcat package looks like it should be able to do the same kind of screen capture as this script, but it doesn't seem to handle the pixel format on my device (the image is recognisable, but looks like it only got the red channel).

I removed maguro from the list of supported devices because cat'ing /dev/fb kills it. According to tvoss

"2013-10-14 15:24:38 tvoss jibel, yup, that comes down to an issue with the maguro fb driver"

Running the script from my desktop, I can confirm that it captured the screenshot very nicely on a Nexus 4 (mako) with Ubuntu Touch saucy build #100.

I can confirm it too, works great by running ist from desktop. THX. build #100

The script does not work on Nexus 7 grouper - when using multi-boot, will only capture the multiboot screen. Overriding image in framebuffer?

Why shouldn't be packaged and seeded on the images by default?
After all it would be nice to take screenshots without a computer.

How about the problem in maguro? Will it be left out unsupported or are there any plan to fix it?

@Inoe, I don't have a maguro, and it has been reported that cat'ing /dev/fb freezes the device. If anyone knows a safe method to dump a frame buffer on maguro, please stand up or better provide a patch. Thanks.

on Mako it capture only black screen - image#205

To the script of lp:~jibel/+junk/phone-tools

This only show:
E: Device '' is not supported.

Then I saw, that there is no ro.cm.device in getprop.

Now, I'm only getting black pictures...
