Fedora 20 on a Thinkpad X1 Carbon (20A7)

Time to try out some new hardware.  My experience so far with the Thinkpad X1 Carbon has been great and will get even better over time.  Most of the things that I’m going to cover in this blog have already been fixed in various projects and I expect that many of them will land in Fedora 21.  However, until that time, I want to make sure that Fedora 20 users can have a great experience with the Thinkpad X1 Carbon (model 20A7), assuming they are willing to tweak a bit.

Step 1 – Disable UEFI Boot for installation

To do an easy install just disable the UEFI Boot in your BIOS and hook up your installation source (USB, PXE over the net, etc).  Very simple to get going.

Step 2 – Fix Suspend / Resume and USB3

Resuming from suspend is going to fail because of a problem with the firmware and the USB3 driver.  You have a couple options.  The first is to disable USB3 in the BIOS and move on.  The second if to update your BIOS which is trickier.  Do not update your BIOS using my instructions unless you know exactly what you are doing.  You can brick (i.e. ruin) your machine if you do it wrong.

Option A (Easy) – Disable USB3 in the BIOS

To do an easy install just disable the UEFI Boot in your BIOS and hook up your installation source (USB, PXE over the net, etc).  Very simple to get going.

As for disabling USB3, there is evidently a USB3 driver problem that keep the machine from un-suspending.  I’m going to investigate updating the BIOS to see if it fixes this, but an easy fix for right now is to disable USB3 and suspend resume works great.

Option B (Danger) – Update your BIOS to version 1.13+ (AT YOUR OWN RISK)

I’ll be honest, I even contemplated as to whether to put these instructions in here.  At the end of the day though, I figure I might as well pass along what worked for me.  Seriously though, if you mess up a BIOS update, you can ruin your machine so if you don’t know what you are doing, just turn off USB3.  However, if you want to update the firmware, this is what I did.

Step 1 – Download the geteltorito.pl script.  You can download the one I used here.

Step 2 – Get a USB drive that can be erased and plug it in.  Figure out which device that drive is.  I usually just run ‘fdisk’ to figure out.  Keep in mind that if you see /dev/sdb1 in fdisk, your device is actually going to be /dev/sdb (with no number at the end).

Step 3 – Download the BIOS ISO image from here.

MAKE SURE YOU GET THE BIOS FOR YOUR MODEL NUMBER LAPTOP.  For example, I downloaded the driver ‘BIOS Update (Bootable CD) for Windows 8.1 (64-bit), 8 (64-bit), 7 (32-bit, 64-bit) – ThinkPad X1 Carbon (Machine types: 20A7, 20A8)‘.  The filename was gruj08us.iso.

Step 4 – Convert the downloaded ISO to a bootable image, named bios-update.iso

perl geteltorito.pl -o bios-update.iso gruj08us.iso

Step 5 – Copy that bootable image to your USB drive.  I’m using /dev/sdx below which you need to replace with your USB device.  Double check that you have the device name right for your USB drive and run:

sudo dd if=bios-update.iso of=/dev/sdx bs=512K
sudo sync

Step 6 – Reboot and press F12 to get the boot menu and boot from the USB.  Follow the instructions to update your BIOS.

Step 3 – Add MattOnCloud Repository

I’ve created a yum repository that contains a RPM that contains various fixes and repositories used in this blog.  I’m keeping the source on GitHub and pull requests are definitely appreciated.  To install my repository, run:

sudo rpm -Uvh https://files-oncloud.rhcloud.com/yum/RPMS/x86_64/oncloud-repo-0.4-1.fc20.x86_64.rpm

To apply the fixes, then run:

sudo yum install thinkpad-fixes

Step 4 – Update GNOME

Since the Thinkpad Carbon X1 has a very high resolution screen, you are going to want to get GNOME 3.12 HiDPI support.  If you don’t, a lot of the windows and text are going to be crazy small.  My RPM provides a repository to a backported version of GNOME 3.12.  So after installing, you just need to run:

sudo yum update

Go get a coffee since that is going to be a lot of packages.  After it’s done, logout and login or reboot your machine.

One you have GNOME reloaded, you are probably going to want to tweak your applications to scale their resolution correctly.  I followed the instructions in this article:

https://wiki.archlinux.org/index.php/HiDPI

Step 5 – Update Synaptics

The trackpad support for the Carbon is a little shaky in Fedora 20 by default as well.  The good news is that the 1.7.6 release backports some of these fixes.  Luckily you can get this release early by just installing from Fedora’s Koji RPM server:

sudo yum install http://kojipkgs.fedoraproject.org//packages/xorg-x11-drv-synaptics/1.7.6/2.fc20/x86_64/xorg-x11-drv-synaptics-1.7.6-2.fc20.x86_64.rpm

I found a great configuration from Major on his blog as well.  I started with that configuration and have made several tweaks – I think the setup is getting pretty solid.  I also add the syndaemon to disable the touchpad for a second after typing.  I’ve found this let’s me keep the touchpad fairly sensitive but avoid random taps when I’m typing email, etc.  I’ve added my configuration to the fixes RPM.  After you boot, you should run the following if you like the configuration and don’t want the settings to be updated via the settings widget:

gsettings set org.gnome.settings-daemon.plugins.mouse active false

I’ve also added a non-tap version of my synaptics settings that I’m currently using.  Curious on people’s feedback as to whether they like the tap settings or click settings better and I’ll make that the default.  You can find the non-tap setup here.

Step 6 – Screen Brightness / Keyboard Backlight

Good news is that adaptive keyboard support is coming soon for Linux.  I’ll update once that is in a kernel that we can get at.  The bad news is that after a suspend, the adaptive keyboard is blank and doesn’t work.  We depend on that for backlight and brightness so we need a workaround.  Luckily the thinkpad-fixes provides them.  It ships with two scripts in /usr/bin to adjust backlight and brightness.  You can run them with:

# Brightness options (dim to bright)
sudo brightness dim
sudo brightness normal
sudo brightness bright

# Backlight options (dim to bright)
sudo backlight 0
sudo backlight 1
sudo backlight 2

A co-worker pointed out that you can also use the brightness slider in the top menu bar drop down (right below the volume).  That is a much easier way to set the brightness if you aren’t in a terminal.  I’ll leave the script for now but might end up removing it.

Step 7 – Fedy

I highly recommend running Fedy to setup the other miscellaneous features such as codecs and font rendering – http://satya164.github.io/fedy/.  Lately I’ve been using the Numix theme and the Infinality fonts and like them quite a bit.  You can install the Numix themes from Fedy and also the improved font rendering with Infinality.  I set the osx style fonts with:

$ sudo /etc/fonts/infinality/infctl.sh setstyle
Select a style:
1) debug       3) linux          5) osx2         7) win98
2) infinality  4) osx          6) win7         8) winxp
#? 4
conf.d -> styles.conf.avail/osx

To switch to the Numix theme, you’ll want to add the GNOME extension for User Themes by going to the following location – https://extensions.gnome.org/extension/19/user-themes/.  Then install the GNOME Tweak tool via Fedy and launch it and select Numix in all the theme options.

Lastly, I highly recommend the Dash to Dock extension as well.  I think it’s one of the best extensions out there – https://extensions.gnome.org/extension/307/dash-to-dock/

Hope this blog helps a new Fedora user out there get up and running!
