useful for filing bugs etc:

Note on Screen orientation:

xrandr -o 1 turns screen to landscape mode (xrandr -o 0 to go back to ordinary portrait):

xrandr -o 0 # default 
xrandr -o 1 # landscape - from right side 
xrandr -o 2 # upside down 
xrandr -o 3 # landscape - from left side 


[edit] Locally from the device

You can grab screen shots manually by using the following command on your Neo:

# cat /dev/fb0 >myscreenshot_001.raw

You can then convert this on your pc with fb2png by using the following command:

# fb2png myscreenshot_001.raw myscreenshot_001.png 9 480 640 16


You can also push a screen capture back onto the display:

# cat myscreenshot_001.raw >/dev/fb0


If you want to show a sequence of screens in an animation you can use convert. Once you have all your screen shots as .pngs try:

# convert -delay 25 -dispose Background +page myscreenshot_*.png -loop 0 animated_test.gif


The command

# fbgrab filename.png

directly creates a PNG on the Neo.

Note: You can get the fb2png binary from this RPM package. The original website seems to be dead and fb2png is not packaged in debian.
