+Linux FAQ
+
+Q. Which distros of Linux does Leap Motion support today?
+A. Ubuntu 12.04 LTS, 12.10, 13.04, 13.10, or later
+
+Q. How do I install the Leap Motion package?
+A. Run:
+ sudo dpkg --install Leap-1.2.0-x64.deb
+
+Q. What if I'm on 32-bit Ubuntu?
+A. Run:
+ sudo dpkg --install Leap-1.2.0-x86.deb
+
+Q. How do I install the 32-bit Leap Motion software on 64-bit Ubuntu?
+A. If you have some reason for doing this, for Ubuntu 12.10 and older please
+ prepare your system with the following command:
+ sudo apt-get install ia32-libs
+ For Ubuntu 13.04, the convenience alias ia32-libs has been removed and you
+ must explicitly install:
+ sudo apt-get install libc6:i386 libX11-6:i386 libgl1:i386 libglu1:i386 \
+ libxi6:i386 libxrender1:i386 libsm6:i386 libfontconfig:i386 sni-qt:i386 \
+ libfreetype6:i386 libxinerama1:i386 libasound2:i386
+ For Ubuntu 13.10 and newer, the multiarch process may be entirely different.
+
+Q. How do I uninstall?
+A. Run:
+ sudo dpkg -r leap
+ Or if you installed the 32-bit package on a 64-bit system:
+ sudo dpkg -r leap:i386
+
+Q. Which dependency packages are required?
+A. Mesa OpenGL and libXxf86vm to name a couple. dpkg or your package manager
+ of choice will report any missing dependencies.
+
+Q. How do I install the missing dependencies?
+A. If you have a mostly complete development environment, you might get lucky
+ and not require any additional libraries. Otherwise, you can manually
+ install with commands such as:
+ sudo apt-get install libgl1-mesa-dri libgl1-mesa-glx
+ On Ubuntu 12.10 and 13.04, you may need to substitute with
+ libgl1-mesa-{dri,glx}-lts-quantal or libgl1-mesa-{dri,glx}-lts-raring.
+ For a package manager that can automatically install dependencies, try
+ gdebi.
+
+Q. I get a long list of warnings when installing through the Ubuntu Software
+ Center GUI.
+A. The GUI installer will run Lintian and report warnings such as recommending
+ against placing the binaries under /usr/local/bin. You may click the option
+ to proceed anyway. Alternatively if you use dpkg from the command-line it
+ will not run Lintian and will not display these warnings.
+
+Q. How can I install on Fedora?
+A. For Fedora 16 and later, first download alien (a package converter written
+ in Perl) in .tar.gz format from http://packages.debian.org/unstable/source/alien
+ and unpack. Next, run:
+ sudo alien/alien.pl --to-rpm --scripts Leap-1.2.0-x64.deb
+ sudo rpm -i --nodeps leap-1.2.0-2.x86_64.rpm
+
+Q. How do I uninstall on Fedora?
+A. Run:
+ rpm -ev leap-1.2.0-2-x86_64.rpm
+
+Q. How do I start the Leap Motion pipeline?
+A. On Ubuntu the Leap Daemon should already be running. You can then run:
+ LeapControlPanel
+ From there you can right-click the tray icon to get a drop-down menu with
+ various options.
+ To restart the daemon (if necessary), run:
+ sudo service leapd restart
+ On non-Ubuntu distros, if leapd is not installed as a service, you may run:
+ sudo leapd
+
+Q. Where is the rest of the Linux documentation?
+A. Most of our notes regarding Linux are in this README. We are still working
+ on making a more accessible web version.
+
+Q. Which window managers are supported?
+A. GNOME with Unity, the default for recent releases of Ubuntu. You should
+ interact with your desktop locally as it is unlikely to work through VNC or
+ any other remote desktop connection.
+
+Q. Can I use the Leap Motion Linux SDK inside a virtual machine?
+A. As of today this does not work well. Oracle VirtualBox does not have fully
+ functional USB emulation in 64-bit mode. Even in 32-bit, you USB
+ authentication is not reliable and you may require special OpenGL drivers
+ to run the Visualizer.
+
+Q. The LeapControlPanel seems to be running but no tray icon appears.
+A. For Ubuntu 12.10 and earlier, the Unity desktop environment uses a whitelist
+ to avoid intrusive tray icons. Add LeapControlPanel to the whitelist with:
+ gsettings set com.canonical.Unity.Panel systray-whitelist \
+ "$(gsettings get com.canonical.Unity.Panel systray-whitelist | sed "s/]$/, 'LeapControlPanel']/")"
+ If your system tray whitelist becomes messed up over time, you may reset it
+ with:
+ gsettings reset com.canonical.Unity.Panel systray-whitelist
+
+ For Ubuntu 13.04 or later we have a new problem. Qt 5 does not yet support
+ Status Notifier Items (SNI) via the sni-qt plugin. If you are running
+ Unity Dash, look carefully in the top-left corner and you may see a
+ tiny Leap icon hidden next to or inside the dash. You can then right-click
+ that icon. We are working on a proper implementation to match the functionality
+ that existed with Qt4.
+
+ If you still cannot find the trya icon, you can at least skip to the
+ settings panel with:
+ LeapControlPanel --showsettings
+
+Q. LeapControlPanel crashes on startup because it cannot find libqxcb.so
+A. Qt 5 has more dependence on plugins, and you could hit this error if you
+ install the software to a non-standard location. You may be able to
+ work around or debug this issue using the QT_PLUGINS_PATH and
+ QT_DEBUG_PLUGINS environment variables.
+
+Q. The GUI reports that the Leap Daemon is not running.
+A. First, attempt the basic troubleshooting steps just like on Windows or Mac
+ OS X. Run:
+ sudo service leapd status
+ And check your cable, do not connect through a USB hub, verify that other
+ devices work through that same USB socket. If you can install Windows on
+ the same system, verify that the Windows version of the Leap Motion software
+ works on this system.
+
+Q. It still reports that the daemon is not running!
+A. There could be any number of problems remaining. To execute leapd directly and
+ see the output, run:
+ sudo service leapd stop
+ sudo leapd
+
+Q. Fails to launch the recalibration or diagnostic visualizer applications
+ form the GUI.
+A. For debugging purposes you may run any of the helper applications directly
+ from the command-line, e.g.
+ Visualizer
+ Recalibrate
+
+Q. leapd was working before, but reports no data now.
+A. One common pitfall is running more than one instance of leapd at a time.
+ If you plan to run leapd directly from the command-line, first disable the
+ service:
+ sudo service leapd stop
+ To inspect, run:
+ ps -A | grep leapd
+ and kill off any rogue processes.
+
+Q. Where can I get Touchless for Linux?
+A. At this time, OS interaction is not supported on Linux. Sorry! You may find
+ some mouse emulation examples on developer.leapmotion.com under the Links
+ and Libraries section.
+
+Q. leapd, LeapControlPanel, Visualizer, or Recalibrate crashes on exit.
+A. This is a known issue and we are investigating.
+
+Q. I occasionally get a kernel panic.
+A. We have observed this and are investigating.
+
+Q. How to install on another Linux distro such as CentOS?
+A. At this time we are only supporting recent versions of Ubuntu. However, if
+ you'd like to port the package to another distro you probably have
+ sufficient tools at your disposal. To view the Debian package, unpack it
+ with the 'ar' and 'tar' commands and take a look. The 'alien' package
+ converter mentioned above may also come in handy.
+
+Q. I have too many issues when trying to run the LeapControlPanel GUI. These
+ involve dependencies, window manager issues, Mesa OpenGL problems, or my
+ video card driver.
+A. You can use leapd without the GUI. It runs as a daemon.
+ Note that to change any configuration settings you will have to edit
+ ~/.Leap\ Motion/config.json
+ We do not have any documentation for the various settings, but you could
+ figure things out by playing around on Windows.
+
+Q. (SDK downloaded separately) Sample.java compiles, but when attempting to
+ run, I get an error about unable to load libLeapJava.so
+A. Java seems to have trouble searching for native libraries without some
+ guidance. Try:
+ LD_LIBRARY_PATH=. java -classpath .:LeapJava.jar Sample
+
+Q. (SDK downloaded separately) How do I build and run Sample.cs?
+A. For the C# example, first install mono:
+ sudo apt-get install mono-gmcs
+ From there, building Sample.cs should be the same as on Mac OS X.
+
+Q. (SDK downloaded separately) How do I build and run Sample.cpp or Sample.py?
+A. The C++ and Python examples work out of the box and the command-line syntax
+ is similar to that on Mac OS X.
+
+Q. (SDK downloaded separately) Why isn't the Screen API working?
+A. The Screen API and corresponding ScreenLocator tool are not currently
+ supported on Linux. Sorry!
+
+Q. (SDK downloaded separately) How do I build the Examples?
+A. To build examples such as FingerVisualizer and MotionVisualizer, make sure
+ to first install a few libraries:
+ sudo apt-get install g++ libgl1-mesa-dev libGLU-dev libX11-dev libXi-dev \
+ libfreetype6-dev libxinerama-dev libxcursor-dev libasound-dev
+ For Ubuntu 12.10 and 13.04, you may need to substitute libgl1-mesa-dev with
+ libgl1-mesa-dev-lts-quantal or libgl1-mesa-dev-lts-raring.
+ From there you should be able to find the appropriate Builds/Linux subdir
+ and build with:
+ make SHELL=/bin/bash
+ On other distros it's possible to build with just 'make'. Unfortunately,
+ because Ubuntu's default gmake shell is dash, we must specify SHELL.
+
+Q. (SDK downloaded separately) Where are the FlockingDemo and GesturesDemo?
+A. The Cinder library is not supported under Linux. We would welcome someone
+ from the community to port these examples to another framework.
+
+Q. (SDK downloaded separately) UnitySandbox has its binary, but why isn't the
+ source code in the Linux package?
+A. Unity 4.0 introduced support for Linux 32-bit and 64-bit build outputs.
+ However, this does not mean that the Unity Editor can run under Linux. If
+ you would like to modify this code, download the Leap Motion Windows SDK and
+ open up UnitySandbox in the Unity 4 Editor.
+
+Q. (SDK downloaded separately) I get "no such file or directory" when attempting
+ to run prebuilt binaries such as FingerVisualizer on 64-bit Ubuntu.
+A. We included 32-bit binaries as the least common denominator across
+ 32/64-bit hardware and Linux distros. If you have 64-bit Ubuntu 12.10 or older,
+ you can set up with:
+ sudo apt-get install ia32-libs
+ or (for Ubuntu 13.04 and newer):
+ sudo apt-get install libX11-6:i386 libgl1:i386 libglu1:i386 libxi6:i386 \
+ libfreetype6:i386 libxinerama1:i386 libasound2:i386
+ or it may be easiest to build the Examples from source code (see above "How
+ do I build the Examples?").
+
+Q. I have a question that is not answered in this README.
+A. Please go to the developer portal and post in the forum or questions
+ section.
+
+Q. I am a Linux guru and can tell you how to do <insert something here>.
+A. Great! Please post your suggestions on the forum.
+
+Q. The Linux version of the Leap Motion SDK is too buggy. Why did you release
+ this crap? I hate you.
+A. Users in the community have strongly expressed that they would prefer an
+ early releases of the Linux SDK compared to nothing at all. We hope that
+ through you and other Linux experts in the community that we may quickly
+ gather feedback to improve upon the Linux SDK.
