[X2Go-User] Centos 7

  Under CentOS 7

  I've updated to the latest kernel provided in the El Repo repository,

      kernel-ml.x86_64   3.19.3-1.el7.elrepo   @elrepo-kernel

  They have no version configured with pre-emption and this version without

does not provide smooth video over x2go, very jerky and laggy like the stock kernel.

  If I build a kernel from source from kernel.org, even using the same

conf, and install it:

make clean; make; make modules_install install

  The entire process proceeds without error but it breaks something

horribly in grub and instead of a boot menu I get a pointer alignment error when I try to boot, so I haven't been able to install a custom preemptive kernel on this machine.

  The packaged kernels install fine, so it's got to be something different

with grub2 that the make file isn't doing.

  I've found instructions on the web for building custom kernels and they

recommend the above procedure which is the same as Centos6, but it does not work for me.

  Anyone with any pointers?
