Broken

It’s all broken.

The TV was destroyed by a raging four year old and Wii remote.

My phone isn’t receiving iMessages over cell.

The lone PC in the house was (on purpose) upgraded to Windows 10.

My RAID DAS is flashing red just two days after I copied all of my data to it.

Bacteria has invaded my sinuses and lungs.

On the plus side, I’ve got a wonderful wife and family. I’ve got a job to go to tomorrow. I got a sweet new Santa Cruz patch from Ollie Crate and today I installed Grafana and InfluxDB … so I guess it’s not all bad.

Installing Nvidia Drivers on RHEL or CentOS 7

Most users of Nvidia graphics cards prefer to use the drivers provided by Nvidia. These more fully support the capabilities of the card when compared to the nouveau driver that is included with the distribution. These are the steps to install the Nvidia driver and disable the nouveau driver.

  • yum -y update
  • yum -y groupinstall “GNOME Desktop” “Development Tools”
  • yum -y install kernel-devel
  • Edit /etc/default/grub. Add “rd.driver.blacklist=nouveau nouveau.modeset=0” to “GRUB_CMDLINE_LINUX”
  • grub2-mkconfig -o /boot/grub2/grub.cfg
  • List available kernels: awk -F\’ ‘$1==”menuentry ” {print $2}’ /etc/grub2.cfg
  • Use grub2-set-default to set the updated kernel to the default. The kernels are enumerated starting at 0
  • Reboot
  • Download the appropriate Nvidia driver for your card
  • Switch from graphical to text mode: systemctl isolate multi-user.target
  • Run the Nvidia driver installer
  • Remove the nouveau driver: yum remove xorg-x11-drv-nouveau
  • Backup old the old initramfs: mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
  • Create new initramfs: dracut /boot/initramfs-$(uname -r).img $(uname -r)
  • Reboot

Why I Hate the Linux Frame Buffer

This is probably pretty petty, and it’s easily fixable, but damn … it’s annoyingly slow at scrolling text.
