+DisplayLink Ubuntu Software Release Note
+
+Version: 1.2.65
+Date: 5th October 2016
+
+DisplayLink DL-5xxx, DL-3x00 Firmware Version: 9.0.37.80577
+DisplayLink DL-41xx Firmware Version: 9.0.37.80577
+Extensible Virtual Display Interface version included: 1.2.64
+
+=============================================================================
+=============================================================================
+
+
+A. Introduction
+===============
+
+This is DisplayLink Driver Software v1.2.1 for Ubuntu. It provides initial, production quality support for DisplayLink USB 3.0 devices on specific variants of desktop Ubuntu Linux.
+
+The driver enables video support for products using DisplayLink USB 3.0 technology. Standard native Ubuntu drivers provide support for DisplayLink audio and Ethernet interfaces.
+
+
+A1. Important notes about DL5xxx, DL-3x00 and DL-41xx Firmware
+=======================================================================
+
+This software release contains an embedded firmware image. DL-5xxx, DL-3xxx and DL-41xx devices will be automatically upgraded with this firmware upon connection if required.
+
+The upgrade is silent, therefore screens connected to DL-5xxx, DL-3xxx or DL-41xx devices may require a few seconds to appear when devices are connected for the first time, or after devices have been used on other platforms and OSes.
+

+H.  Limitations & Known issues

+
+C. Issues fixed
+===============
+
+Issues fixed since DisplayLink Driver Software v1.2 for Ubuntu (1.2.58)
+-----------------------------------------------------------------------
+
+Extensible Virtual Display Interface module is not compatible with Linux kernel 4.8. (23848)
+
+
+Issues fixed since DisplayLink Driver Software v1.1 for Ubuntu (1.1.62)
+-----------------------------------------------------------------------
+
+High CPU usage with no activity on DisplayLink monitor. (22444)
+
+Kernel warning in dmesg after connecting DisplayLink monitor. (22530)
+
+Segmentation fault could occur while stopping DisplayLink daemon. (22536)
+
+DisplayLink systemd/upstart service is only loaded when a DisplayLink device is connected. (23187)
+
+
+D. Supported O/S variants
+=========================
+
+This release has been prepared to be compatible with Ubuntu 16.04 and Ubuntu 14.04. Other variants and editions may be compatible if they meet minimum O/S requirements, but are not supported by DisplayLink.
+
+The Software contains binaries which work on Intel x86 platform (32 bit and 64 bit).
+Minimum supported Linux Kernel version is 3.16.
+Minimum supported Xorg version is 1.16.
+
+E. Release components
+=====================
+The Software consists of an open-source kernel mode driver (EVDI) with an accompanying library (libevdi), and a supporting binary application compatible with Intel x86 platform.
+Source code for the open-source components can be found at DisplayLink's GitHub, https://github.com/DisplayLink
+
+F. How to Install
+=================
+
+To install the release, from a terminal window, with root permissions use the command:
+
+sudo ./displaylink-driver-XXXX.run
+
+Where displaylink-driver-XXXX.run is the name of the extracted DisplayLink driver.
+
+The dkms framework is required for installation of DisplayLink. This can be installed with the command: sudo apt-get install dkms
+
+More detailed information on installation can be found at http://support.displaylink.com/knowledgebase/articles/615714#ubuntu
+
+G. Supported Features & Hardware
+================================
+
+This driver will support up to 2 displays connected to DisplayLink devices. More than 2 DisplayLink displays may work, but not supported or tested by DisplayLink.
+
+Resolutions up to 4K are supported on the appropriate DisplayLink hardware.
+
+Device families supported:
+- DL-5xxx
+- DL-41xx
+- DL-3xxx
+
+Support for DL-1x5 and DL-1x0 devices is provided by the open source udl driver.
+
+H. Limitations & Known issues
+=============================
+
+A list of limitations and known issues can be found here:
+http://support.displaylink.com/knowledgebase/articles/641668
+
+I. Future Development
+======================
+
+DisplayLink are open to suggestions and feedback on improving the proposed architecture and will gladly review patches or proposals from the developer community. Please find a current list of areas we identify as requiring attention below.
+
+- In this release, the user mode driver service is running with root permissions. In future versions, we would like to reduce the privilege level required for this process – e.g. by using a separate low-privileged user and a separate group, to ensure the permissions needed for driving DisplayLink screens are as low as possible.
+
+- The communication between the EVDI kernel module and the wrapper libevdi library is not access-controlled or authenticated. This could be improved in future releases, making it harder to compromise the data EVDI is sending and receiving.
+
+- EVDI kernel module driver is currently a platform_driver, for multiple reasons; most importantly because virtual displays are not discoverable, i.e. cannot be enumerated at the hardware level. EVDI is also a generic device, not tied to any particular kind of device, transport layer or a bus.
