I need some help about kernels, modules and so on.
I've installed CentOS6.5 (fresh install) on a DELL E7440 laptop. After all the updates I get the latest kernel: kernel-2.6.32-431.
But with this config I've a problem: If I close the screen on the keyboard, the laptop hibernate. When I open it the system restart (I connect use ssh to reach the laptop) but the screen remains black (Intel HD Graphics 4400).
I've installed a more recent kernel from elrepo-kernel (kernel-lt-3.10.26-1.el6.elrepo.x86_64) and it solves the black screen problem.
But now I have several errors about => kdump, Starting kdump: ÉCHOUÉ => vboxdrv Starting VirtualBox kernel modules ÉCHOUÉ (modprobe vboxdrv failed. Please use 'dmesg' to find out why) => dkms (requested for VirtualBox) Démarrage de dkms : Error! Your kernel headers for kernel 3.10.26-1.el6.elrepo.x86_64 cannot be found at /lib/modules/3.10.26-1.el6.elrepo.x86_64/build or /lib/modules/3.10.26-1.el6.elrepo.x86_64/source.
but kernel-lt-headers cannot be installed (conflicting with the installed kernel-headers requested by many packages).
You need the kernel-devel package (not -headers) that matches your running kernel.

Thanks Akemi. Now, after a new fresh install of centos and this kernel, the laptop boot properly and when the laptop hibernate after closing the screen the restart is fast and efficient. I also notice a very faster network with these new drivers!
But I think I still have a problem with modules added by virtual box. If I install this application the problem come back as with previous kernel. Mays be hibernation it is not supported with virtualbox and the modules it adds...
