evdi's Introduction

Extensible Virtual Display Interface

The Extensible Virtual Display Interface (EVDI) is a Linux® kernel module that enables management of multiple screens, allowing user-space programs to take control over what happens with the image. It is essentially a virtual display you can add, remove and receive screen updates for, in an application that uses the libevdi library.

The project is part of the DisplayLink Ubuntu development which enables support for DisplayLink USB 3.0 devices on Ubuntu. Please note that this is NOT a complete driver for DisplayLink devices. For more information and the full driver package, see DisplayLink Ubuntu driver.

This open-source project includes source code for both the evdi kernel module and a wrapper libevdi library that can be used by applications like DisplayLink's user mode driver to send and receive information from and to the kernel module.

How to use

See libevdi API documentation for details.

EVDI is a driver compatible with a standard Linux DRM subsystem. Due to this, displays can be controlled by standard tools, eg. xrandr or display settings applets in graphical environments eg. Unity, Gnome or KDE.

Minimum supported kernel version required is 4.15. DisplayLink have checked the module compiles and works with Ubuntu variants of kernels up to 5.5. Although other vanilla Linux kernel sources are used for Travis CI job, newer kernels, or kernel variants used by other distributions may require extra development. Please see below to see how you can help.

Future Development

This is a first release. 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.

Compatibility with distributions other than Ubuntu 18.04/20.04 LTS is not verified. Please let us know if you make it work on other distros - pull requests are welcome!
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.

Fedora 24 - works after updating drm API calls

After updating Fedora 24, the kernel is 4.6.3-300.fc24.x86_64
Tried to install displaylink-1.0.335-1.x86_64.rpm but evdi kernel module would not load. Made a few source code mods to get it to build. Now installed and looks ok.

evdi_fb.c :
dma_buf_begin_cpu_access() and dma_buf_end_cpu_access() have only 2 args (*dma_buf and dir) instead of the 4 parameters used in evdi_fb.c. The API calls will succeed with only these two args so the 2nd and 3rd parameters in each call can be dropped.

Change parameter list:
static int
evdi_framebuffer_init(struct drm_device *dev,
struct evdi_framebuffer *ufb,
struct drm_mode_fb_cmd2 *mode_cmd,
struct evdi_gem_object *obj)
to

static int
evdi_framebuffer_init(struct drm_device *dev,
struct evdi_framebuffer *ufb,
const struct drm_mode_fb_cmd2 *mode_cmd,
struct evdi_gem_object *obj)

then install the driver using the drmk

(module may already be registered if you tried to install the RPM)
dkms add -m evdi -v 1.0.335
dkms build -m evdi -v 1.0.335
dkms install -m evdi -v 1.0.335

You should now be able to start the displaylink service. When it is enabled, it should autostart when you plug in the display. This works with the ASUS MB169 display.

Arm Ubuntu support

Hi, I am wondering if there will be release for ubuntu arm support in near future? I am planning to use Asus MB 169B+ with Nvidia Jetson TX1 development board, which will run Ubuntu 14.04 for arm.

Painter reconnection every 10 seconds, causing a 1 sec freeze

On my external connected monitor via
(a) - dockingstation D3100
(b) - pluggable thunderbolt3-to-hdmi-connector
I get a ca 1 second long freeze every 10 seconds.

In my journal, everytime the lag occurs, I get these Lines:

Nov 10 13:16:20 XPS kernel: evdi: [D] evdi_detect:69 (dev=1) Painter is connected
Nov 10 13:16:20 XPS kernel: evdi: [D] evdi_painter_get_edid_copy:192 (dev=1) 00 ff ff

What could cause these freezes?
How can I remove them?

Extreme lagging on DisplayLink screens

I managed to get the driver working on my Fedora 23 (KDE/Plasma 5) machine (granted an unsupported configuration). However the attached screens are basically unusable because of a repaint delay between 1 and 2 seconds. Interestingly the results vary depending on the application, i.e. Google Chrome is completely unusable while I can bear using Firefox on the displaylink screens. Additionally I experience a flickering cursor on my laptop screen (display link screen is fine). Any pointers?

displaylink-driver fails to understand kernel version correctly

I'm not sure whether this is the right forum to report this, but when I tried to install the displaylink-driver (as per this guide: http://support.displaylink.com/knowledgebase/articles/615714#ubuntu) I'm getting a script error saying that my kernel is too old (even though it's a rather new one). Script output:

Verifying archive integrity... All good.
Uncompressing DisplayLink Linux Driver 1.0.68 100%
DisplayLink Linux Software 1.0.68 install script called: install
Distribution discovered: Debian GNU/Linux unstable (sid)
Unsatisfied dependencies. Missing component: Kernel version 4.1.0-1-amd64 is too old. At least 3.14 is required.
This is a fatal error, cannot install DisplayLink Linux Software.

It's probably because the script only checks minor versions instead of checking both major and minor, and should be easy to fix.

Missing information in libevdi docs

I started playing around with libevdi but the docs seem incomplete. When I try to add a new device evid_add_device returns 2 whereas the docs state that

Return value: 1 when successful, 0 otherwise.

There is no new cardX within /dev/. Trying to create a new device as non-root leads to the correct zero return value.

As this is the first call libevdi I guess it's no programming error. Nevertheless, the return value 2 should be described in the docs.

Distribute firmware in linux-firmware repo

Firmware ucode is most usually distributed within the following repo:

http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git

Please distribute DisplayLink ucode in this manner so distro's may automagically pick it up.

Thanks

USB Displays go black for two seconds

This appears in dmesg

Cursor Glitches on Gnome 3.20 and KDE Plasma

Hi, I've been using evdi and the DisplayLink driver with my StarTech 4K USB 3.0 to HDMI adapter and I am very happy with how it works, except that have noticed that around borders for windows and widgets that the cursor will flicker and trail or will simply disappear. I did some testing as I have both Gnome and Plasma installed on Arch Linux and it happened in both. I also noticed that I was using an older version, so before commenting, I pulled down the current source and built it and installed it but the issue continued. If you would like a video, I can probably put one together.

Thank you

compilation with kernel 4.7 fails

apparently some drm apis changed. compilation fails on 4.7.

DisplayLinkMana doesn't start, gets terminated with signal SIGABRT

Everytime i try to start or restart the DisplayLink-Service a Core-Dump gets created and the service isn't starting. The errors i could extract out of the dump were:

Rotation property

Xrandr does not seem to recognize a rotation for displaylinked monitors. Is it possible to add this?

Displaylink on Gentoo causes system freeze unless booting to Windows first.

Hello,

I installed the latest Displaylink 1.2.65 and evdi 1.2.64 on Gentoo linux.
And when I boot with the Displaylink connected or connect it while in X I get a complete system freeze.
But, when I boot Windows 10 first, then reboot back to Gentoo it does work. So it seems to have a issue with the init of the device.
I have Dell Precision 7510 with a USB-C port connection.
I contacted Displaylink support, but they referred to the evdi lib for different Linux brands compatibility.

I don't know about the "Edid too large", but as I said, previous versions worked fine.

Plasma 5.8 compositor issues

Running Latest kernel 4.8 with latest KDE Plasma 5.8 there are some major issues with the compositor and libevdi. The issue is the compositor no longer does proper partial screen paints even without DisplaylinkManager running or displaylink device plugged in. the only way to "fix" this is to enable full screen refreshes but that causes major performance issues. The issue is only present when libevdi is loaded, if i boot without the module everything is normal.

Add support for gamma ramp

When using a tool like RedShift the gamma ramp via randr is modified.
It would be nice if this feature could be added. Is this even possible?

Ubuntu 16.10: kernel BUG at mm/usercopy.c:75!

Hello,

Thank you for providing this driver (generally). With this and the DL software, I was able to (generally) run two external monitors off Ubuntu 16.04. I have recently upgraded to 16.10 (about to hit beta) and had disabled evdi/DisplayLink as the older release did not yet support the newer 4.8 kernel in 16.10. I saw the release of 1.2, though, and updated. It leads to a kernel BUG and hard freeze of my system consistently, unfortunately, and I'm fairly sure it's in the evdi driver itself (or interaction with some other subsystem).

I am happy to debug, provide more logs, etc!

uname -a = Linux pitfall 4.8.0-14-generic #15-Ubuntu SMP Tue Sep 20 22:02:02 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Couple of independent questions from this bug:

Would you have any interest in perhaps getting this driver integrated into the Ubuntu kernel? It's not impossible to get out-of-tree, but open-source, drivers built with the Ubuntu kernel -- you'd get more test & integration exposure, etc.
If 1) were true, you might be able to get the other parts of DisplayLink packaged or maybe snapped (http://snapcraft.io/) up, so that it would be instantly accessible to end-users?

[caveat, I'm a Canonical employee and Ubuntu developer]

Cursor movement is visibly slow (tearing) when primary screen (laptop) is closed/turned off (.e.g with lid closed). When laptop screen is on (lid open) cursor is behaving normally (fast, no tearing) as it is by default on laptop screen only.

CPU usage of DisplayManager does not seem to vary between these two.

Kernel traces on 4.4 with Fedora

On Fedora 23 with kernel 4.4.7-300.fc23.x86_64, I'm getting a lot of kernel traces but everything seems to work fine.
This is on a MacBook Pro with Intel Iris 6100 gpu connected to a Dell D3100 hub.

An example of such a trace (they are all the same).

Nitpick: Add proper git tags

Hi, minor nitpick here but if i run git describe --tags returns:

v1.2.55

but git describe returns

`v1.0.68-47-g6fe15f50fb``

I would expect to see v1.2.55 or similar to sync up with releases

Issue connecting USB screen Lenovo LT1421 with Displaylink 1.2.64 on Kernel 4.7 and 4.8

Hello,
I have had a quick look through the open an closed issues, please advice if already familiar or solved.
As soon as I connect the USB screen, it shows an image, freezes, turns black and keeps re-connecting.

I assume that between 11 and 17 seconds user enter password in gdm and perform login.

After dock station reconnect external screen get enabled.
Booting with Linux 4.4.0-43 left from Ubuntu 16.04 does not workaround this issue - I still get same error message with Linux 4.4.0-43.

Stage & Mainline the driver

Hi,

This is a really annoying way to get hw going in 2016+. Can DisplayLink please possibly get this module into staging of the mainline kernel tree so the various distro's such as RHEL (used here) will automatically pick it up.

Kind Regards,
Edward.

Is there anything I can do or try? Anybody got this to work with Ubuntu 15.10?

I understood that support for kernel 4.x is absent, but soon 16.04 LTS is out of beta next month and current 15.x and 16.x will be probably the most used distros with kernel 4.x - is there plan to support it anytime soon?

Thanks

Module doesn't compile with DRM changes in Linux 4.5

There are kernel DRM API changes in the upcoming 4.5 kernel. The evdi module doesn't compile with these changes.

Strange power/refresh/paint issues with Ubuntu 15.10

Hey there, I managed to make a Lenovo ThinkVision LT1421 to work with the Displaylink driver on Ubuntu 15.10 on a Lenovo Thinkpad T450s, however I'm still running in issues that make the usage of the display very unreliable. I thought of sharing these findings with you in the hopes you can improve the driver.

I've originally posted some here
http://askubuntu.com/questions/753164/ubuntu-doesnt-look-like-sending-power-to-an-usb-port-used-by-a-device-that-uses

but I will summarize below:

The Displaylink driver will work only if the Intel Linux Graphics Driver is completely removed. Apparently this is due a modified libdrm package which evdi doesn't like. However, I wish this issue could be addressed, as the Intel drivers do in fact improve power management and resolve other issues I had with other programs and hardware acceleration (mainly Chrome).
Once intel drivers are uninstalled, the screen will work, but not properly, as detailed below.
if I start ubuntu, then connect the display with either 1 or 2 usb, it will work (i can see the refresh rate is better with 2) -- note this display comes with a usb Y cable (the kind that splits into 2-male USB plugs to draw more power if necessary, I tried in my tests to work with either one or 2 plugs connected, it doesn't make a difference)
if I disconnect the display, and reconnect it, it won't work. It may turn on and all, but it will refresh very slowly, to the point of being unusable.
if anything related to screen displays refreshes/restarts, such as the displaylink service or for example if I update my software for display calibration (DisplayCal), the screen will flash and will enter in this state where it doesn't paint properly
if I start my laptop with my display connected already (either to 1 or 2 usb) it won't work, it will only function in this bad state - sometimes it will even keep the same appearance as I left it since last reboot (same partially painted areas)
disconnecting and reconnecting again after the screen has entered in this state, no matter what, it will always bring it back in the same unusable mode. I have to restart ubuntu with the screen disconnected, then connect the screen and hope it won't hang
very interestingly, whenever the screen is in this failed state, it will show 2 extra displays in my "Screen" settings - one correctly labelled like Lenovo Thinkvision 14" and the other labeled as FNM 0"

Displaylink drivers not working for Debian 8.5 (issues with providers)

As reported here (drivers compiled for Debian) I apparently have some issues with setting up the 2nd external screen.

For your convenience I quote the part of the issue which I couldn't yet solve (according to the creator of the compiled version for Debian it seems a general driver related issue, rather than the version specifically compiled for Debian):

xrandr --listproviders

prints

Provider 0: id: 0x45 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 3 associated providers: 0 name:Intel
Provider 1: id: 0xfe cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting

However when I try to attach the displaylink adapter to my (1st) external screen I can move the mouse to the other screen.. but the screen remains black.

I tried to play a bit with arandr by trying different resolutions and positions (this actually seems to work to change position or resolution but doesn't solve the issue)
I also tried xrandr --output HDMI1 --auto --right-of eDP1.

Same result.
I didn't try with 2 2nd external screen but the display doesn't show up even for the 1st one, unless I use directly my computer's HDMI port.

Any clue? Am I doing something wrong here?

I also noticed in arandr in "Outputs" there is DP1 (besides eDP1) but it's gray and I can't interact with it

Fix compilation for 4.8

some changes were made to the drm subsystem.
mainly drm_connector_(un)register_all are no longer exported as they are called on drm_dev_(un)register automatically

I might or might not cook up a patch during the course of the day (dependant on how busy I am.)

Friendly wish to Update Driver for Kernel 4.6.0-rc2

I am trying to get the Driver work on the newest Linux Kernel (4.6.0-rc2) and get the following errors on executing make.
I know the official support is limited but can some smart developer have a look into this? I have a feeling these are some minor Problems which can be solved easy.

After reboot I run the setup again and get the same warning, do I neet to uninstall the driver before by self?

evdi framebuffer problem

System:
archlinux
kernel 4.8.4-1

Problem:
I have a displaylink device, so I have evdi also installed.
I have a problem on my dell xps 13 9360. I have a little screen freeze every ~10 secs, on hdmi display via D3100 docking station, via usb-c-to-hdmi and on the laptop screen. Everytime it lags, I get an message in my journal what could raise this error? how could i fix it?

Still kernel traces on 1.1.61

I'm trying the new displaylink driver and the 1.1.61 evdi version here from github.

Although everything seems to work so far, it still throws kernel traces:

Fedora 24 AMD64: evdi_painter_crtc_state_notify:362 Painter does not exist!

As it says on the title.

OS: Fedora 24 AMD64
Kernel: 4.6.4-301.fc24.x86_64
DisplayLink software: 1.1.65 (Installed from https://github.com/ssaavedra/displaylink-rpm/releases/download/v1.1.65-5/displaylink-1.1.65-5.x86_64.rpm)
Displays: ASUS MB169B+ x2

The ASUS logo is displayed then the screen turns back off when plugged in. No additional screens appear in any RandR tools.

Displays are known good: they work on this machine in Windows 10.
The RPM is known good: the driver works on another machine with Fedora 24 AMD64 and kernel 4.6.4-301.fc24.x86_64.

It doesn't seem to matter if I do one at a time or both of them at once.

Closed-source NVIDIA driver support

Hi,

thanks so much for releasing DisplayLink driver for linux, it is a great commitment for all powerusers who need more screens to work ;)

A question, as mentioned in support, displaylink on linux doesn't work when primary GPU is managed by closed source driver from Nvidia or AMD.

As I saw in dmesg, both evdi and DisplayLinkManager work and they correctly detect attached monitor, so I guess the problem is somewhere in X subsystems like xrandr, right?

Is there any workaround or fix for that?

thanks

does not work on Kensington SD4000 / Ubuntu 16.04 (linux 4.4 kernel)

when I installed the vendor binary it said my kernel version was not supported.
but it seemed to install the firmware and load the module OK anyways.

blacklab% lsusb
Bus 002 Device 003: ID 17e9:4344 DisplayLink
...
everything accessible throught the usb is working, but no second monitor shows up in the ubuntu prefs.

I git cloned, and built the kernel driver from source, it gave no errors, installed that .ko, and that worked fine, but no better result. just does not show up in the display settings dialog.

Firmware?

The package available Ubuntu for the DisplayLink docks contains 2 firmware files:

ella-dock-release.spkg
firefly-monitor-release.spkg

Those firmware are supposed to be uploaded if necessary to the docks, but there's no code in evdi, library or module, to support it. And no mention as to whether they are freely redistributable.

libevdi API documentation is missing

This issue is a placeholder for pushing the API documentation for libevdi.

DisplayLink on D3100 is incredibly slow

Just tried the new release. I've a Dell D3100 dock connected to a Fedora system, compiled the kernel module and installed the DisplayLinkManager and companions. I've disabled selinux because of tons of complaints I didn't want to investigate for testing.

Now - for the first time, I can see something on the secondary monitor. BUT it is so incredibly slow, that it can't be used at all. I'm not sure how I can debug that. Any ideas?

Ubuntu 16.10 running slow

Seems this is happening to a few of us:

http://www.displaylink.org/forum/showthread.php?p=81728&posted=1#post81728

I have a Precision 5510, and connected it to a Dell monitor with both a Dell USB 3 dongle, and a Dell D3100 dock (which is "linux compatible". Even with the latest Displaylink drivers, I'm seeing terrible performance on the second monitor. However, if I connect the monitor directly to the laptop's HDMI port, everything runs fine. I've noticed the following:

Using bumblebee, running glxspheres on second monitor using Displaylink I get 1 fps when on intel graphics (both with Displayport, and HDMI connected to dock).
Using bumblebee optirun, I get 200fps.
Using bumblebee on the laptop monitor, I get 60 fps when on intel grpahics.
Using bumblebee on the laptop monitor, I get 200 fps when using optirun.
If I switch to Prime graphics using the dock, I get 2000 fps on the second monitor, but the internal monitor shuts off.

I've also run it using the open source drivers, and I get 60fps on the internal screen, but only 1 fps on the external one. Optirun doesn't work with the open source driver.

I'm currently running it with a seperate HDMI cable, which gives ok performance, but means the expensive D3100 dock is essentially a USB + ethernet hub; functionality which can be got from a £15 component. The same laptop runs when connected to an external 4K monitor using a Plugable thunderbolt 3 adapter, so I have to come to the conclusion that Displaylink just doesn't work.

Wayland support

Hi all,
do you have any plan to support wayland?

It looks to be the new standard for Linux (in Arch Linux already it is) and it is a little frustrating I can't use my dell dock at work.

Thanks and have a nice day :)

Fix for displaylink-installer.sh

Here's an improved version of detect_distro which makes it work not only on Ubuntu, but also on forks of Ubuntu such as Linux Mint, Elementary OS, etc. I'm sending this patch using my external monitor powered by DisplayLink on Linux Mint :-)

detect_distro()
{
  if which lsb_release >/dev/null; then
    lsb_release -u > /dev/null 2>&1
    lsb_release_exit_code=$?
    if [ "$lsb_release_exit_code" = "0" ]; then
      # if this is a fork then use -u to find upstream version
      local R=$(lsb_release -d -s -u)
    else
      local R=$(lsb_release -d -s)
    fi
    echo "Distribution discovered: $R"
    if [ -z "${R##Ubuntu 14.*}" ]; then
      SYSTEMINITDAEMON=upstart
    elif [ -z "${R##Ubuntu 15.*}" ]; then
      SYSTEMINITDAEMON=systemd
    else
      echo "none"
    fi
  else
    echo "WARNING: Unknown distribution, assuming defaults - this may fail." >&2
  fi
}

Kernel 4.2 Support

When will 4.2 be supported?
