I upgraded to Ubuntu 11.10 on a one-core laptop. With Gnome shell, Xorg eats between 50 and 60 % of my CPU and gdl_box eats the rest of the CPU. That makes the computer unusable, though I could use it with Compiz and another mode than Gnome shell to have a normal CPU consumption.
I then upgraded in the same way on a 8-thread laptop (Intel i7 processors). With Gnome shell, Xorg and gdl_box take each a full thread at 100 %, i.e., eating 2 full threads out of 8. The computer is still very fast, but the processor temperature increases to 75 degrees C leading to fans turning at full speed.
I saw in other threads people having a similar issue with Unity, but not with Gnome shell. The small laptop has an ATI card while the big one has an Nvidia one. Does anyone has a suggestion about what is happening and how to solve the problem? Thanks in advance for any piece of information.
