Hi there,
i recently installed centos 6 64bit version on my HPProBook4530s Laptop. i then issued the command to update the kernel only. it updated the kernel to latest stable 2.6.32-358.14.1.el6.x86_64 kernel. After update what i got is that my touchpad is not working. i am 1000% certain that new kernel caused this problem. so, what i should do with the kernel to overcome this problem or any other suggestion?
Warm Regards, Ahmed Dawood
Hello Ahmed, Nothing else besides kernel has changed? I'd reboot and revert to previous kernel to test the issue. -Brandon

Also, for each boot instance, save off and compare /var/log/Xorg.0.log as this is where such problems will be reported. (To "save off" here, you should do something like "cat Xorg.0.log > Xlog.kernel.1".)

Thanks Ken, i tried to got a clue of problem in Xorg.0.log file in both kernels. but i was unable to get it. The thing i notice is that in old kernel Xorg log file is
(II) config/hal: Adding input device ImPS/2 Synaptics TouchPad (II) XINPUT: Adding extended input device "ImPS/2 Synaptics TouchPad" (type: MOUSE)
Where in the new kernel Xorg file contains
(II) config/hal: Adding input device SynPS/2 Synaptics TouchPad (II) XINPUT: Adding extended input device "SynPS/2 Synaptics TouchPad" (type: TOUCHPAD)
so does it make a difference?

It's not likely that files were simply renamed for no reason. So I'm thinking yes, there is a difference. And this is exactly the kind of difference we were looking for. So let's dig a little deeper.
So try this: Boot each kernel and each time save the output of lsmod (e.g.: "lsmod > lsmod.kernel.1") and make separate copies of the file, /etc/X11/xorg.conf and then then look for differences in those two pairs of files.

Weren't there any lines in your log files like this?
"(II) Loading /usr/lib/xorg/modules/...."

Differences in the modules which were loaded with one kernel as opposed to the second kernel.
Try chose the old kernel via grub after you reboot your laptop.

CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centosNot Available in old kernel is
Loading /usr/lib64/xorg/modules/input/synaptics_drv.so
Not Available in New kernel is
(II) UnloadModule: "intel" (II) Unloading /usr/lib64/xorg/modules/drivers/intel_drv.so (II) UnloadModule: "fbdev" (II) Unloading /usr/lib64/xorg/modules/drivers/fbdev_drv.so (II) UnloadModule: "fbdevhw" (II) Unloading /usr/lib64/xorg/modules/linux/libfbdevhw.so (==) Depth 24 pixmap format is 32 bpp (II) Loading sub module "int10" (II) LoadModule: "int10" (II) Reloading /usr/lib64/xorg/modules/libint10.so
I got no differences in module when loaded in old and new kernel. Also, if i install a newer linux kernel or elrepo kernel can solve this problem?
