(and install the Nvidia driver)
1. append Append this to the kernel line in /etc/grub.conf
blacklist=nouveau
make Make sure you are editing the correct kernel line. if If you are not sure, you can add it to all the kernel lines.
...
blacklist nouveau options nouveau modeset=0
3. rebuild Rebuild initial ram disk. eg For example, if you your kernel is 2.6.32-573.22.1.el6.x86_64, then do this:
...
# dracut -f /boot/initramfs-2.6.32-573.22.1.el6.x86_64.img 2.6.32-573.22.1.el6.x86_64 -v
That will built build and put a new initial ram disk in /boot/.
Then reboot. You You can do run "/sbin/lsmod | grep nouveau" to verify it worked.
This process worked for me on host tid-pc80031 on 8-Apr-2016.
Service now ticket INC0089358.If you want to see all the hosts that have blacklist=nouveau appended to the running kernel (ie, /proc/cmdline), then you can look in system.info:
$ grep -l blacklist=nouveau /afs/slac/g/scs/systems/system.info/*/cmdline
Or if you want to see all the hosts that have the nouveau module loaded, you can look in system.info like this:
$ grep -l nouveau /afs/slac/g/scs/systems/system.info/*/lsmod
To install and activate the nvidia driver (stop X server, install driver, start X server):
Make sure no one is logged into the console or else you will kill their session.
