Hi szzsqing1

2 quick suggestions

re not getting 6.7.1 to run on a computer that will run 6.4.4 perfectly well - you might try using the cheatcodes at boot time

<knoppix nodrm no3d>

- this worked for me on an old Compaq desktop- when the graphics display just seized up completely when trying to boot without them - somewhere on the dvd you will find other cheatcodes to fix graphics problems so you might find better ones - actually the 'somewhere' on my DVD is:

/media/sr0/KNOPPIX/knoppix-cheatcodes.txt

re getting the Hungarian language pack and dictionaries - I've had to find a workaround even for en-gb language packs and dictionaries as often the debian repositories synaptic uses don't come up with compatible packages for your libreoffice/openoffiice main packages

- so what I have done is go and look for the package I want on either the Debian or the Ubuntu [heresy] packages sites [google package name] and find there the language package or dictionary you want [somewhere among lenny, wheezy, squeeze or sid] with the same 3 figure version names - so if your main installed libreoffice packages are 3.3.0 [check in synaptic] then this is the package version you need for your lnguage pack - not 3.3.1 or 3.3.2 or whatever. So far I've managed to find what i need somehow, downloaded it and installed it with:

dpkg -i *.deb

I know this isn't the orthodox answer but it does sometimes work perfectly well - and uses a lot less download quota than reinstalling a whole new version of your office suite just to get a compatible language pack and dictionary.

Best wishes, John
