I am new to this OS. I have only worked with Windows so far.
I have tried to run Ubuntu without installing it onto my computer. Everything looks OK during installation, but when trying to use it, I had no keyboard (PS2) and mouse (PS2 via USB convertor). After a few minutes to screen turns black (I think it is a screensaver or something). The only thing I can do is turn of the computer and try again. After 5 times I gave up the installation.
After investigation at start-up I've noticed that there were some strange messages on the screen.
Purging configuration files for gdm-guest-session ...
[ 76.257910] end_request: I/O error, dev sr0, sector 1413064

[ 96.653302] Buffer I/O error on device sr0, logical block 353267
The sector errors occure only @ the following sector numbers: 1413064, 1413068
The block errors occure only @ the following block numbers: 353266, 353267
Does anybody have a clue about what is going wrong during installation?
