^ Of course.
I (blindly

) did install a recent screen saver but checking the mrinstaller.log I found
Code:
Not enough space left to process ss 0.47.N U, skipping . . . :(
Freed some space, reinstalled and all is good now:
Code:
[root@kindle root]# cd /mnt/us
[root@kindle us]# fbgrab fbgrab.png
Skipping 0 bytes
Resolution: 600x800 @ depth 4
Converting to Gray8
Allocating 480000 bytes for conversion buffer
Now writing PNG file (compression 4)
[root@kindle us]#
Thanks.
