(and install the Nvidia driver)
1. append this to the kernel line in /etc/grub.conf
blacklist=nouveau
make sure you are editing the correct kernel line. if you are not sure, you can add it to all the kernel lines.
2. Also, add the following to /etc/modprobe.d/blacklist.conf
blacklist nouveau options nouveau modeset=0
3. rebuild initial ram disk. eg, if you 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 and put a new initial ram disk in /boot/.
Then reboot. You can do /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.
sudo init 3 cd ~ksa/nvidia/ sudo sh ./NVIDIA-Linux-x86_64-340.96.run sudo init 5
