OK, I've done what you said but I don't understand anything. $ sar -I XALL 2 1 | less Shows that 0 interrupt is the problem (if I understood well).
$ cat /proc/interrupts Show that the 0 interrupt refers to timer. (See screenshot) What can I do ? I had to disable lapic timer to prevent system from freezing everytime I don't use mouse or keyboard. ** Attachment added: "proc.png" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/657990/+attachment/4118334/+files/proc.png -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/657990 Title: System freeze when i'am not moving the mouse or typing.
