 +===== 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:
 +
 +<​code>​
 +[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
 +</​code>​
 +
 +Save it as /​etc/​systemd/​system/​setpci-xhci-workaround.service and enable it with <​code>​systemctl enable setpci-xhci-workaround.service</​code>​
 +
 +===== 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 <​code>​idle3ctl -s138 /​dev/​sda</​code>​ 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. [[http://​gorka.eguileor.com/​vbox-vmware-in-secureboot-linux/​|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:
 +
 +<​code>​Section "​Device"​
 + Identifier "​Card0"​
 + Driver "​intel"​
 +
 + Option "​Backlight"​ "​intel_backlight"​
 +EndSection</​code>​
 +
 +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 <​code>​synclient tapbutton1=1 tapbutton2=3 tapbutton3=2</​code>​ to enable tapping.
