I have been using Ubuntu from a long time but I had never been in the depth of Ubuntu. At present I am using Ubuntu 12.04 LTS
. It was getting hanged randomly and fast when I was using Firefox. I search a bit and found that possible solution is to upgrade kernel.
Earlier my kernel was(I am not sure though) 3.5.x
something and then I upgrade it to 3.8.8
using this link and then after reboot when I open Ubuntu, graphics which was ugly earlier was perfectly fine but no other peripheral work other then VGA port.
I don't know what I had done wrong, and I am unable to post any other related info as even internet is not working in Ubuntu. Had I done anything wrong like upgrading Linux kernel of Ubuntu 12.04
to a kernel version which is not supported?
please help me.
