Trying to get an operating system that works.

[justme2]

The good news is that my keyboard problems seem to have been solved but I still cannot type to the terminal when asked to enter my password following bitsnpcs's command line still & this problem seems to have even spread to the original command line that I used & mentioned in my original post  :o

I am tempted to buy the official DVD but I expect the problems would just continue 

When you type a password in the terminal, no characters are displayed - its a security thing! Just type the whole password and press enter.

As for buying non-official DVDs from anonymous sources, forget it, you could be 'opening a can of worms'.
I see you are in the UK so if you wish, I'm sure someone in UK would offer to provide you with a dvd with the official download burned and ready to boot, or the loan of a bootable flash stick. Such is the support from the linux community. 
I have never had a problem with creating bootable dvds but I have certainly had problems trying to use the latest releases on old PCs, where hardwear support may be lacking. All (3) my PCs are old but all run LL2.8 very successfully.

I understand your frustration but your problems 'could' be self inflicted - we have all suffered in such ways!

Lets help you get this sorted (assuming your hardware is suitable) so you can be 'Happy linux user' instead of 'SICKOFLINUX' ....
