Also I am wondering where I can check whether I have the proper video driver instaleld,
The answer is in
sysinfo is under K-menu (Kieker style)--> Tab Computer --> System Information
At the bottom-right you can see the video driver in use.
And I am sure that the video driver issue (nvidia, ati, etc 3D-support) will be solved before the final release,
Otherwise Pardus will have a major issue.
That's why I didn't make a bug about this issue at this moment.
You can always make a bug report, and see what the response is.
A minor annoyance is the clock being used in the taskbar: it has no option in the settings to set it to 24hour, I really dislike am/pm time watching< i am very much used to e.g. 23:12 instesd of 11:12 pm....
To solve this:
System Settings > Regional & Language > Country or region: (change)
and select Europe, ........ etc.
Restart the computer and the time, money ....... has been changed.
The above is general KDE stuff.
And to change the language:
Open Package Manager.
Search for "-nl" or "-de" or "-fr" or ......
Check at least "kde-I10n-..." and "glibc-locales-..." (and openoffice)
Install these packages.
And change the language in System Settings > Regional & Language > Add Language.
And change the language in OpenOffice.

And "System Information" is only available when you have the Kickoff menu and NOT with the Classic and Lancelot menu.
