I see the same problem as TnS. On my two Kobo Touchs.
When setting
Code:
echo "3" > /sys/class/graphics/fb0/rotate
before starting plato, the rotation is correct. Works nice on my KT running FW4.6.9995. Does not work on my other KT running FW 2.6.1 or so, even though the orientation is now correct.
EDIT: After playing a little bit with plato, I am very impressed. Even Devanagari-fonts (for Hindi and Sanskrit) are displayed correctly in epubs. I did not check whether the latest Koreader versions are also able to do this now.
