I was trying to download a paint program yesterday when my laptop suddenly started running extremely slowly (it took five minutes to close a Chrome tab at one point). I managed to run top, and the "compiz" process appeared to be taking up a lot of resources, so I killed it--I didn't have access to another computer to google what it was, and it was 90 minutes before an important deadline I had to submit something for, so I just took my best guess. Things started acting really weird, but I was able to submit my stuff. Today, I tried to boot up Ubuntu multiple times, and it just hangs on the purple screen indefinitely. As an Ubuntu novice, could killing Compiz have caused this?
Thanks in advance!
