Hi, I'm a complete newbie to Linux, by that I mean that I know nothing! I've had my Acer Aspire for a while now and kept being prompted to upgrade my browser to Firefox 3.6. I thought I'd finally tackle this and after much rummaging around I managed to upgrade. Whilst at it I thought I'd also update my flash player plugins and again seem to have managed. However..I didn't know at the time if my netbook was 64 or 32bit so I installed 64bit stuff - turns out I'm on 32bit. Anyway, I went back and got the 32 bit stuff as well and I thought everything was great but now I can't change my volume settings with the Fn with up and down keys anymore. I get the little display but with no green progress line in it. Volume works but only through the main volume settings rather than with the keys. I know it's a minor thing but I'd like to know what I've done and how to fix it.
How do I get my volume controls to work as before and display as before?
How do I know if I'm 32 or 64 bit? where would that be apparent?
Having installed the wrong thing how do I go about uninstalling?
Should I just give up now and get a man in?! lol
Any help would be SO much appreciated.
