Hi, guys. Thank you all for your kindness help. This bug seems finally solved on my computer by change the kernel version. I tested 3 different kernel images, and they are: 1. I added a PPA line 'ppa:kernel-ppa' in my synaptic package repository, and update the software package list. Then tried 2.6.39-0 kernel which listed in synaptic package list. Unfortunately, my GUI still lockup, and even I try to remote login my laptop, restart GDM, the computer completely dead and I have to push the power button to hard reboot it. Seems newer kernel also has the problem, I removed this kernel. 2. The second kernel I've test was downloaded from: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.37.6-natty/, my system is i386 with 4G RAM, there is only generic version. It works fine, GUI never lockup, but when I test LibraOffice Calc, the Calc crashed few times (it's acceptable). The shortage of this kernel is: there are just 2.7G RAM available. So, I continue search other choices. This kernel still remains in my computer. 3. After some search in google, I found it here: https://launchpad.net/ubuntu/+source/linux/2.6.37-12.26/+build/2125798. I downloaded 3 debs including PAE kernel image and the header files.
Till now, after 1 days test, the 2.6.37 PAE kernel image is running very fine on my laptop. I enabled compiz effect in traditional gnome desktop, opened several XLS files in LibraOffice Calc, the animations and shadow effect looks so lovely. And the most important: the damn GUI lockup never occurred again till now. yeah, few software crashes sometime, but, no GUI lockup. Maybe more people will also meet this problem when they purchase a new computer with Sandy-Bridge CPU. Hope someday the bug can be fixed after more lockup case be reported.
