My cursor acts as usual. It occasionally turns into a big vertical arrow-like thing, and I got the well known radeonhd bug [1] - "The cursor shows weird corruptions at some points of the screen", although I'm not using the radeonhd driver. However, using this option, after starting firefox everything gets extremely laggy, and I can interact with my machine with the keyboard or mouse with 4 seconds intervals. After commenting this option, the behaviour returns to the usual.
