Notes

Tested with:

  • Fedora 20 amd64, kernel 3.16.7 and 3.17.3 (run from an external HD)
  • Fedora 21 amd64, kernel 3.17.1 and 3.17.3

On F20, add the following to your kernel command line to avoid random freezes in X:

i915.semaphores=1

If the system still freezes, disable PPGTT:

i915.enable_ppgtt=0

Fedora 20 couldn't install at all with UEFI enabled, not even with the automatic partitioning. Fedora 21 installs fine, though.

If any of the USB devices fails with the error -110 (not enough power), reset the USB controller with setpci:

setpci -s 00:14 d0.w=0x0

Do not do this from a live image!

The above command is also useful for solving the erratic behavior of the Bluetooth adapter. Either add it to rc.local (remember to chmod +x it if you're creating a new file) or create a systemd unit to run it earlier on boot:

[Unit]
Description=setpci fix for xHCI
DefaultDependencies=no
Before=sysvinit.target local-fs.target
 
[Service]
Type=oneshot
ExecStart=/usr/sbin/setpci -s 00:14 d0.w=0x0 
 
[Install]
WantedBy=basic.target

Save it as /etc/systemd/system/setpci-xhci-workaround.service and enable it with

systemctl enable setpci-xhci-workaround.service

Hard drive

This notebook's hard drive is a WD Blue with a “feature” called Intellipark (aka idle3), which makes the drive turn off after 8 seconds of inactivity. It's advised that you increase this timeout while using Linux, not only because it's a bad idea to have your hard drive powering off so often, but because Linux does a lot more background writes that cause frequent wakeups of the drive. You can use idle3-tools, available in Fedora repositories. After installing it, run

idle3ctl -s138 /dev/sda

to change the timeout to 5 minutes, which is the maximum allowed; higher values cause random clicks and a pronounced performance drop.

Disabling Secure Boot

First of all, set a supervisor password. The setup utility won't let you disable Secure Boot nor manage trusted bootloaders unless you do so.

I ran into issues with USB 3.0 and the Bluetooth/card reader in Legacy mode, even on Windows, so I suggest you don't use legacy boot if you're planning to use these devices. Just disable Secure Boot; if you're worried about dual booting, Windows doesn't need it actually.

If for some reason you need Secure Boot, be aware that loading unsigned modules (i.e., out-of-tree) is forbidden on Fedora. Sign your modules to work around this.

Screen brightness

The brightness controls are recognized, but you can't use them in the VT. Fedora 20 still provides the useless acpi_video0 interface that is used instead of the working intel_backlight. To fix this, create a file named /etc/X11/xorg.conf.d/10-intel.conf with the following contents:

Section "Device"
	Identifier "Card0"
	Driver "intel"

	Option "Backlight" "intel_backlight"
EndSection

Then you will be able to change brightness from X.

You can have these controls working in the VT if you boot with the “acpi_osi=” option (without quotes), but then they won't work with X.

Dealing with the touchpad

You'll notice that the touchpad has a button under its surface. If tapping is not configured by default (which is the case with Fedora live images), clicking with one finger is the equivalent of the left button; with two fingers, the right button; and with three fingers, the middle button. From the command line, run

synclient tapbutton1=1 tapbutton2=3 tapbutton3=2

to enable tapping.
