This is a really nice idea, these forums. They are quite helpful. I am still quite new to the idea, but think it is good.
Anyway, I installed ubuntu11.10 yesterday. It is running off my C drive, in which the main operating system is Windows Vista. I have given ubuntu about 30gb. I use a wubi installer, and have the dual-boot option.
When I'm in ubuntu, I notice that it freezes a lot if I run a few processes at a time. For example, if I am installing some software from the "software centre" and while I wait, I open up a browser to use the internet, one of the two will freeze. And lately, my software centre seems to "not respond" and I have to "force quit". If I want to install something from there, I have to make sure that only the software centre is running, nothing else.
I thought maybe it's because the OS is still new, and after a few updates it will be fine...
