In Knoppix 7.2 the graphic utility arandr does not work for me anymore.
Every time I want to configure my two monitors (DVI + extended desktop to HDMI) now I need to use "KDE System Settings" (systemsettings -caption "%c" %i).

Here is the output of arandr I see when I execute it on a command line:

root@Microknoppix:/home/knoppix# arandr

o.modes.append(Size(int(a) for a in d.strip().split(" ")[0].split("x")))
ValueError: invalid literal for int() with base 10: '1080i'

How to make arandr work again?
