Same thing here (Latitude X1 with Pentium M, same graphics board and driver). Has been that way already with the 2.6.15-23 kernel
When just booting into the Gnome desktop my CPU load then stays at 5-6% with the linux-386 kernel, whereas it stays at 40-50% with the linux-686 kernel. But I rembember people with other hardware posting this problem in the Web-Forums, although I can't find the posts at the moment. Only common thing was, that everybody encountering this problem used a Pentium M of some sort. -- high cpu on xorg (~40%) https://launchpad.net/bugs/50180 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
