I have a USB 3.0 docking station connected with my laptop having LinuxMint 17.3. I can't manage to install DisplayLink driver on it. I could make it work with Ubuntu 15.04, but with LinuxMint it wan't recognize external monitor, even though there is no error message during the install procedure. I tried to follow some proposal on DisplayLink forum , and I tried to modify installation file so SYSTEMINITDAEMON had systemd or upstart values, but none of these worked. Since I already found some posts reported it worked for LinuxMint 17.2, I guess it's possible, but I couldn't find exact instructions if something else should be changed in installation script.

I’m running Fedora 42 installed on an external NVMe (2TB) drive connected to my MacBook Pro (Early 2015). My system setup is as follows: CPU: Intel i7 (Broadwell, MacBook Pro) Graphics: Intel Iris 6100 Fedora Version: Fedora 42 (Workstation) Display Adapter: JUA365 - USB™ 3.0 to Dual HDMI™ Multi-Monitor Adapter (DisplayLink based) DisplayLink Driver: Installed EVDI module: Loaded Secure Boot: Disabled DisplayLink service: Running fine Everything seems installed properly — but the external monitor still doesn’t turn on or get detected. I've tried: Manually restarting displaylink-driver.service Reinstalling EVDI via DKMS Reconnecting and powering monitor Verified logs (journalctl) — no clear errors I’m wondering if anyone using JUA365 or similar DisplayLink adapters has encountered and solved this issue on Fedora 41/42? Is there a known issue with DisplayLink adapters (like JUA365) on Fedora 42? Could this be a missing udev rule or a permissions/device node creation issue? Anyone using a similar setup successfully? Any tips, logs to check, or workarounds would be greatly appreciated. Thanks in advance!

System: Ubuntu 24.04 Kernel 6.11.0-25-generic Lenovo Thinkpad P1 Gen 3 Asus MB166B (the source of the messages) I get the message *reset high-speed USB device number ## using xhci_hcd* approximately once per second. The actual display is working fine with no visible indication that something is wrong. The only reason I noticed it is that an unrelated issue had me looking at messages. Issue persists on both onboard USB2.0 ports, I don't have a dock/powered hub handy to test on. Log below starts with plugging the device in:

I'll add that I did see the 2014 question with a similar title , but that appears to be specific to one mouse and this is... isn't.

I installed a additional touchscreen to my laptop over displaylink. The screen itself works fine. But the vendor / model / serialno is set to "unknown". I need these value to map the touchscreen to the monitor. How can I name the display correct? EDID seems to be correct. hwinfo --monitor shows correct data. .config/monitor.xml is unknown. I'm running Fedora 40 / gnome 46 / wayland

I installed my new TETRA split keyboard. https://www.kickstarter.com/projects/747287659/tetra-keyboard-split-touch-type Keyboard and display works fine. But I cannot map the touch event to the display because it is not recogniced.

I'm running Fedora 40 / Gnome 46 / wayland. The display is connected via displaylink on usb-c.

Is there a fix I can do on my system? Should I file a bug evdi or another bug tracking of a package? The last kernel update failed. I had to remove the evdi package. Thereafter the update succeeded. I need evdi for displaylink-driver package to use a docking station. When trying to install displaylink-driver I get below terminal output with a postprocess error having exit code 10. The mentioned make.log is here . There are not many options for me to get the docking station to work. One bug filed for pop os seems to address this, however, unanswered. It is not the first time I install this package, so one comment in the release note pointing to uefi sec workaround should not bother me. However, tried it, and failed, because I cannot install evdi package. The evdi bug tracker has one issue with post installation return code 10 , however, this one is old and refers to older kernel. With the kernkel 6.1.0-24-amd64 kernel it worked before.

So I have 2 displaylink displays, each shows as a framebuffer device, fb0, and fb1. I am using raspberry pi os, and it will show on one display, but the other is blank, however if I move the cursor over, it shows as an x, which I think indicates it is a blank xserver. I have tried all sorts of different xorg.conf variations, and tried to enable xinemera which does nothing and does not appear at all in the log when enabled. I can address each display using DISPLAY=:0.1 or 0, and lets me open apps. if I use DISPLAY=0.1 xrandr I get details on one of the displays, but they seem separate. my xorg.conf: Section "Device" Identifier "FBDEV 0" Driver "fbdev" Option "fbdev" "/dev/fb0" EndSection Section "Device" Identifier "FBDEV 1" Driver "fbdev" Option "fbdev" "/dev/fb1" EndSection Section "Monitor" Identifier "Monitor0" EndSection Section "Monitor" Identifier "Monitor1" EndSection Section "Screen" Identifier "DL1" Device "FBDEV 0" Monitor "Monitor0" EndSection Section "Screen" Identifier "DL2" Device "FBDEV 1" Monitor "Monitor1" EndSection Section "ServerLayout" Identifier "Default Layout" Screen 0 "DL1" 0 0 Screen 1 "DL2" RightOf "DL1" Option "Xinemera" "on" EndSection and the corresponding log file: X.Org X Server 1.20.11 X Protocol Version 11, Revision 0 [ 634.407] Build Operating System: linux Raspbian [ 634.407] Current Operating System: Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr 3 17:24:16 BST 2023 aarch64 [ 634.407] Kernel command line: coherent_pool=1M 8250.nr_uarts=0 snd_bcm2835.enable_headphones=0 snd_bcm2835.enable_hdmi=1 snd_bcm2835.enable_hdmi=0 smsc95xx.macaddr=E4:5F:01:AF:76:E0 vc_mem.mem_base=0x3ec00000 vc_mem.mem_size=0x40000000 console=ttyS0,115200 console=tty1 root=PARTUUID=84c4adaf-02 rootfstype=ext4 fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles [ 634.408] Build Date: 29 April 2024 03:20:14PM [ 634.408] xorg-server 2:1.20.11-1+rpt3+deb11u13 (https://www.debian.org/support) [ 634.408] Current version of pixman: 0.40.0 [ 634.408] Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

Anyone who has/is successfully using Display link with evdi for external monitor on his arch linux? I’ve been struggling to make it work. I was on lts kernel before and learnt evdi is working best with latest arch kernel 5.16, so i switched to latest kernel. Even then it fails to work. I do see external monitors with display link when i use dmesg. But i never get the external monitor activate. If it helps, I’m using Hp USB C docking station. I could share more info if needed. I have been following arch wiki for display link. I have tried mode setting and other trouble shooting tips/workarounds in wiki. None of it worked yet. Hardware used: System76 Lemur Pro 10 Any help or guidance is appreciated. #evdi #displaylink #arch

# Symptoms 2 out of 4 monitors don't light up after suspend.

Aug 14 09:06:37 xps-9320 systemd[1] : Started DisplayLink Driver Service.

# What I tried: 1. Upgrade the DisplayLink driver to 5.7.0 then 5.8.0 2. Upgrade evdi to 1.13.1 then 1.14.1 3. Restart the service Nothing worked. So far the most effective way is to logout/login, which is much faster than reboot. Somehow the DisplayLink driver causes a long hanging (120 secs) during startup/reboot. # Updates 1. Oct 31, 2023 - problem solved after upgrading to kernel 6.2.0-36 2. Jan 17, 2024 - upgrading from Linux Mint 21.2 to 21.3 somehow stopped the service. I had to start the service manually.

I had arm-based server ubuntu and I showed outside temperature to it's monitor over FIM.
For some reasons I had to move to server with some virtual machines and I installed server ubuntu on it.
I would like to do the similar as before. I have USB-to-VGA adapter from DisplayLink.com. I connected it to host and connected to virtual machine, installed driver for Ubuntu. And ubuntu sees my monitor. It shows some messages but not console. So it shows the following: ls /sys/class/drm/*/edid | xargs -i{} sh -c "echo {}; parse-edid Are there any ideas on how to redirect main monitor of Ubuntu to this external monitor? Thanks. Rg, Dmitry

Trying to run two screens connected to a ThinkPad USBC dock, which is connected to my laptop via USBC. The dock is connected as it charges and works with external mouse / keyboard. I have followed the instructions to the letter on DisplayLink section of the arch wiki. When running xrandr --listproviders, only one provider shows up. The displaylink provider does not show up: `Providers: number : 1 Provider 0: id: 0x48 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:modesetting` I have tried all versions of evdi (evdi, evdi-git, evdi-compat-git). udl is installed and running and I have edited the 20-evdi.conf file. I have updated my system, re installed displaylink, all versions of evdi, etc. I have tried any debugging solutions I can find.

Error occurs when running modinfo udl Using kernel 6.4.11-arch2-1. In my config I have: CONFIG_DRM_UDL=m # CONFIG_FB_UDL is not set modinfo udlfb returns the same error. This problem arose when debugging an issue with displaylink. Displaylink does not run at all and I believe it is due to the udl module missing. I have followed all debugging steps on the archlinux wiki and anything eles I can find on here/google. How can I resolve this?

Struggling with some devices often not functioning upon suspend , I came across the SE U&L question of [reloading drivers](https://unix.stackexchange.com/questions/113828/how-to-find-and-reload-specific-driver-from-kernel). In my case, a few devices are not detected, and I can see the driver (displaylink-driver.service) is loaded but inactive/dead.  So, is it possible to start drivers up again? $ lsusb # missing usb devices (detected by $ lsusb before the issue) Bus 004 Device 005: ID 17ef:a357 Lenovo USB3.1 Hub Bus 004 Device 004: ID 17ef:a359 Lenovo ThinkPad Lan Bus 004 Device 003: ID 17e9:6015 DisplayLink ThinkPad Hybrid USB-C with USB-A Dock Bus 004 Device 002: ID 17ef:a356 Lenovo USB3.1 Hub $ sudo systemctl status displaylink-driver.service ● displaylink-driver.service - DisplayLink Driver Service Loaded: loaded (/lib/systemd/system/displaylink-driver.service; static) Active: inactive (dead) May 26 14:50:56 debija systemd[1] : Starting DisplayLink Driver Service...

I use a script to setup all my screen when I plug my laptop on my dock

xrandr --output eDP1 --off
xrandr --output DVI-I-2-2 --mode 1920x1080 --pos 0x0 --rotate inverted
xrandr --output DP1 --mode 1920x1080 --pos 1920x0 --primary
xrandr --output DVI-I-1-1 --mode 1920x1080 --pos 3840x0

But the rotated screen is not really rotated... Some stuff are rotated, some not. What is not rotated : - Mouse cursor - Wallpaper - Any window display What is rotated : - Windows button (I mean actions, so to interact with a window you have to click where the button is supposed to be and not where it's displayed) - The side of the screen where mouse come in and out I tried it on gnome and pantheon desktop, and screen are plugged on displayLink (dell d-6000) dock. Do you guys have any idea ? Thanks

Two monitors sometimes wake up from suspend, and other times they do not e.g. . _Specifically_, entering suspend and hitting the keyboard seems to wake up the monitors the first time. But clicking suspend the second time the monitors remain black. As a result USB devices connecting the monitors to the laptop with Displaylink cannot be found, and the Displaylink driver is deactivated. Only reboot works. Other usb connected devices to the dock work, such as keyboard and mouse. The issue seems independent of the lid position and does not occur 'intermittently' . How to troubleshoot? Is the issue due to DisplayLink, suspend, or something else? The following did _not_ work: - turn off USB autosuspend and blacklist in tlp or TLP UI. - thunderbolt-tools , tbtadm approve-all and checking with lspci devices. - Unplugging hdmi or usb-c of the dock. I would not know what I would be doing: - remove /etc/pm/sleep.d/displaylink.sh. - udev rules - blacklist - powertop Some possible involved files

With Debian stable and proprietary drivers on a Lenovo x1 3rd gen--but not with MS windows 10 on an older Lenovo laptop (using the usb-c to usb-a) and a HP laptop (using usb-c)--I have a problem with the *ThinkPad Hybrid USB-C with USB-A Dock*: The USB-devices mouse, keyboard, and headset works fine; but the two monitors do not (akin to Pauxlo's experience ). What to do? 1. forget about using this docking station (costly) 2. install Ubuntu (well, Debian is otherwise nice and installed) 3. try to make DisplayLink for Ubuntu [2] [3] work on Debian (may be quite involved) 4. ask the question elsewhere e.g. on the displaylink forum, on the linux-hardware.org forum, et cetera. 5. other alternatives I have found related issues, some which are solved, others which are still unsolved: - detected on Debian 11 and Debian Testing with "snd_usb_audio" driver according to linux-hardware.org - Debian Buster with a link to solution for arch linux - solutions and non-solutions [7] [8] for Ubuntu distributions - issue on Fedora, solution on RHEL8 and so on - in case of high resolution, apt-get install evdi-dkms libevdi0 has been suggested for Debian [10]

I have setup display link on my elementary OS, but each time i restart my laptop, seems like all the settings gets reset and i have to reinstall display link to get it working again. I do however notice some weird logs while i setup display link executing this command displaylink-debian/5.6.1/displaylink-driver-5.6.1-59.184.run results in the log below

at this point my external monitors start working, but once i restart, i have to start the installation from the very beginning. i suspect the cause for this is somewhere in these logs which keep appearing at the very end

This is a follow-up on [How to get 3 monitors working in Linux Mint 18](https://unix.stackexchange.com/questions/311798/how-to-get-3-monitors-working-in-linux-mint-18) . I am on a Dell Laptop with one HDMI output, but the cables are plugged in on a dock. I highly doubt that the laptop brand/type/version plays any role since anyone has the problem *(unless they have two graphic cards in a desktop pc perhaps?)*. I cannot add more than one other monitor to my Linux Mint 21, plugged in at the laptop, which has just one graphical output. Even on Ubuntu, there is just the official [DisplayLink USB Graphics Software for Ubuntu](https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu) for 20.04 and 22.04, but not for 21.04, though for Ubuntu, there was a fix for this to update the firmware on the dock, see [Ubuntu 21.04 displaylink not working - DisplayLink Forum](https://www.displaylink.org/forum/showthread.php?t=67714) , taken from [Ubuntu 21.04 with three external monitors - Ask Ubuntu](https://askubuntu.com/a/1350597/1110856) . And that would not even work since it is needed for Linux Mint, which only builds on Ubuntu, but needs its own driver for the screens. For Linux Mint, I found much the same problems for earlier versions, like [Setting up multiple screens. - Linux Mint Forums](https://forums.linuxmint.com/viewtopic.php?t=287087) . *(needless to say, but for anyone of you testing this, you need to restart your machine after any DisplayLink driver change)* How to get three screens/displays/monitors on Linux Mint 21?

I am trying to have my Lenovo DisplayLink to work with Manjaro Sway but so far could not manage to have screen signal going through it. I updated my linux to kernel 5.15 I installed the corresponding linux-headers to properly install evdi I installed displayconnect When I run systemctl start displaylink.service It crashes When I log back in a shell without and start sway manually it gives the following error:

Any help would be greetly appreciated

## Symptoms Every few minutes/hours the displays connected to the USB3 DisplayLink dock turn off for a few seconds and back on again. ## Hardware - Dell docking station model D6000 - USB3 connection to HP laptop (happens on at least three different models) - DisplayPort connections to two HP monitors ## OS - Arch Linux - Ubuntu 20.04 ## Software - displaylink 5.3.1.34-4 and other versions ## Logs I was lucky to catch only a few log entries in the journal while one of these instances happened. I've included *all* the raw logs around this time, including before the disconnect and after the reconnect:
