Just reporting that using the
fbgrab tool bundled in a recent
usbnet for the K3 (kindle-usbnetwork-0.57.N-r17925) I get
Code:
[root@kindle us]# fbgrab fbgrab.png
fbgrab: /mnt/us/linkss/lib/libz.so.1: version `ZLIB_1.2.9' not found (required by /mnt/us/usbnet/lib/libpng16.so.16)
[root@kindle us]#
Probably to be expected on a 10 year old device...
