Oh, dearie me.
I got my desktop PC back from the shop on Tuesday, and it's so nice to have it again, after two weeks or more of struggling to learn Linux on my laptop.
I'd noticed, after two weeks on the laptop, a significant slowdown in its speed. What would you do in Windoze? Defrag, run a registry cleaner and delete the temp files, right? Uh, uh, not with Linux.
First of all, it doesn't store its files in a fragmented way, so defragging would be unnecessary. Secondly, it doesn't use a registry. But i found a way to remove the temp files.
So much in Linux requires the use of the Terminal (the equivalent of running Command Prompts in Windoze). To clear temp files i had to open the terminal and enter "sudo apt-get clean" (without quotes). Hey, it worked well, but i had to Google for that information, as none of my Linux help menus seem to work.... ("Sudo" stands for "super user," i.e., adminstrator, and something else. In my case it's probably "d'oh!")
Ah, well, it's been a learning experience, this Linux lark, and i really believe that when one stops learning, one may as well lay down and die. I shall persevere with it. But it's so nice to have the desktop back, large screen monitor, and a keyboard i can use (i was friggin useless on the laptop's touchpad, fortunately i had a spare USB mouse lying around...)
