HP EliteBook 840 G1 & Fedora 20

Some random notes on getting Fedora 20 working on an HP EliteBook 840 G1.

• Brightness keys don't work
  • Edit /etc/default/grub and add acpi_backlight=vendor to the GRUB_CMDLINE_LINUX line.
  • Depending on how you're booting,run the appropriate command to regenerate the grub2 config
    • BIOS: grub2-mkconfig -o /boot/grub2/grub.cfg
    • UEFI: grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
  • Good backlight tips: https://wiki.archlinux.org/index.php/backlight
• Installing w/ bcache
  • If your 840 was purchased with the small SSD cache drive, you can use it to accelerate the hard drive by using bcache. There's a good post on the Fedora Forums: http://forums.fedoraforum.org/showthread.php?t=296015 I didn't follow his post exactly. For example, I use LVM2. I'll update this post later with info on that.
