NOTE: I've installed all updates, so that shouldn't be the reason.
This is probably my fifth day with Linux (Ubuntu 11.04), and although I was impressed the first day, I'm thinking of permanently reverting back to Windows.
Here are some reasons:
I was told that Linux had very quick boot times, but this is not the case. I timed how long it takes from turning on the computer to logging in to the desktop.
For Ubuntu 11.04 it takes me around 40-45 seconds or so to turn on the computer and log in.
For Windows 7, this takes me around 25-30 seconds.
Besides the slow boot times, some applications are running sluggishly slow.
I tried installing Docky, and it lags horribly.
Moreover, I installed Super Tux Kart, and although it runs nearly perfectly, it seems to be using too much CPU. I think it gets to the point where the computer heats up too much and Linux automatically shuts down the computer. So it seems applications aren't being run efficiently.
My hardware isn't too shabby considering what some other Linux users have.
My processor is a Core 2 Duo 2.0 Ghz and I have 4 Gigs of DDR2 RAM, along with a 512 MB dedicated nVidia GPU.
I'm encountering many Graphics problems when I lock my screen, suspend/hibernate, switch user, or even when trying to shut down the computer:
Check the attached picture.
Finally, I'm encountering a really irritating problem concerning my mouse and keyboard. They simply freeze sometimes and stop working and the only way to solve this is either to reboot which takes a while or to suspend which runs me into the graphics problem.

In summary, I'm not at all impressed with Linux, and I'm not even able to see why there's such a huge community for it if it's this bad for everyone. If it's not this bad, then could someone please help me solve my issues?
