On F20, add the following to your kernel command line to avoid random freezes in X:
If the system still freezes, disable PPGTT:
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
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.
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.
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.
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.
