since i've updated my ubuntu to hardy heron, tux manager doesn't work :

[code]$ tuxgdg
Traceback (most recent call last):
  File "/opt/tuxdroid/apps/tux_framework/TFW.py", line 12, in <module>
    from FWObject import GdgFramework
  File "/opt/tuxdroid/apps/tux_framework/libs/FWObject.py", line 34, in <module>

  File "/opt/tuxdroid/apps/tux_framework/libs/TGFXml.py", line 26, in <module>
    import xml.dom.ext
ImportError: No module named ext[/code]

known issue. there are several threads about this, please use search

Since i haven't found any solution for this problem, despite searches I've done, here is the small workaround i've found to make tux tuxgdg work again after updating to Ubuntu Hardy :

in the file /opt/tuxdroid/apps/tux_framework/libs/TGFXml.py, insert the following lines right after the bunch of comments lines (starting by #) :

import sys
sys.path.append('/usr/lib/python%s/site-packages/oldxml' % sys.version[:3])

Additionnaly, I replaced my /etc/udev.rules/45-tuxdroid.rules file by the one provided by enguerran in this post :

Nevermind, i can now run tux gadget manager, but most gadgets doesn't work anymore. I get too many problems for me to manage with simple hacks using my current python knowledge

A solution that worked for me
