I have recently installed Ubuntu 14.04 LTS. It worked wonderfully at first, but then it started to be extremely slow to open and close new windows. The system monitor showed that the processor ran at around 100% although I was nothing special. The "Compiz" process took up around 40% of the processor power.
The problem started a while after I had connected an external monitor. First it worked wonderfully, but after a while the problems started. Maybe there is some problem with compiz that arises when one uses an external monitor. Maybe compiz has a but that is triggered when the graphics-processor sending data to an external monitor. The problem did not disappear immediately when I deselected the external monitor. I restarted but it was still there, but when I started the computer today it worked OK. I do not dare to connect the external monitor again because I do not want to be stuck with the same problem again. I have a Dell U2311H with 1920 × 1080 pixels, while the laptop has 1280 × 800 pixels.
