They had installed some modified Edubuntu's at school.
So I have some questions about setting some things up:
How can we play HD videos? They are made for Windows machines and are in WMV format but we need to play them in our multimedia class but I don't know how - which player, which codecs, etc.
How to properly edit the
/etc/apt/sourcesfile? Anything we try to install via apt-get it just says that E:\ is not available. Which repositories should be put in there so we could be able to install some tools?
Where are viruses/trojans usually put in Ubuntu? I mean in which directories? Because our computers are behaving really slow and we need to check for malware manually - we are not even allowed to install any kind of anti-virus software. What are the usual directories and places for hiding such files, how are they hiddem, how to recognize them, etc.?
Any others nice tricks/tips that we need to know.
