Hello everyone. I'm fairly new to Ubuntu and I like it a lot. However, there's a graphical error which started to happen after the very first bootup. The startup screen (the purple one with the 5 dots that appear) isn't showing anymore. It is replaced by some console technical guff scrolling down my screen (which isn't a problem, because Ubuntu itself works fine, but it just looks a bit rough). Again, on shutdown, it displays some amalgamated mix of more technical jargon, and a terribly lo-res version of the shutdown screen.
Is there any way I can fix this?
Thanks for replying.
