1.4 not working (Ubuntu/Dell D6000)

[castor731]

I only made it work a few random times in the first couple of weeks. I've now been weeks unable to get the screen to display. I only get the keyboard and mouse working.

Powering off and on doesn't help me anymore.

I think I've stumbled on this issue as well. I have two jobs, and both employers have decided on widespread use of Dell Universal Dock D6000. Up until now, I have been able to get two monitors working, while three other monitors don't seem to do anything (I tried five different docks, with various different monitors, didn't keep track, although the successful ones were a bit older in appearance)

The following happens when I plug in the dock.
* The DisplayLink device always gets registered with usb:

lsusb -d 17e9:
Bus 001 Device 011: ID 17e9:6006 DisplayLink

* The evdi kernel module gets loaded
* The DisplayLinkManager service is executed

(By the way, I'm on Slackware64-14.2, with evdi / libevdi 1.5.0 built from source and DisplayLinkManager version 4.1.9.)

In the successful cases, I then have an extra provider if I execute xrandr, which I can activate with xrandr --setprovideroutputsource 1 0. When unsuccessful, nothing else happens. I can replug the device to no avail, I can change between hdmi and display port connections without effect, I can even reboot, but the monitor just sits there doing nothing. I don't get any additional evdi kernel messages either, apart from the regular

evdi: [I] Initialising logging on level 5

I think that this is a bug with DisplayLinkManager. I would very much appreciate a solution or a workaround. I was looking forward to using these docks...

After a few days of struggling, I managed to find a solution on Ubuntu 17.10. Hope this works for everyone having problems with the D6000 dock. Below format is markdown (to lazy to convert it)

## Instructions for fixing the blanking monitor on dock issue within Ubuntu.
**Make sure to reboot after making the changes!**

#### Disable USB AutoSuspend
* `sudo gedit /etc/default/tlp` and change the below value from `1` to `0`

```
USB_AUTOSUSPEND=0
```

* `sudo gedit /etc/udev/rules.d/01-usb-dock.rules`. This will create a new file.

```
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="1bcf", ATTR{idProduct}=="2b95", TEST=="power/control", ATTR{power/control}="on"
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="1bcf", ATTR{idProduct}=="0005", TEST=="power/control", ATTR{power/control}="on"

ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="17e9", ATTR{idProduct}=="6006", TEST=="power/control", ATTR{power/control}="on"
```

#### Disable Display Power Management
* `sudo gedit /etc/X11/xorg.conf` Append the below options to the file.

```
Section "Monitor"
Identifier "DVI-I-3-2"
Option "DPMS" "false"
EndSection

Section "Monitor"
Identifier "DVI-I-2-1"
Option "DPMS" "false"
EndSection
```

#### Disable audio suspend
* `sudo gedit /etc/pulse/default.pa`. Comment out the line indicated below.

```
### Automatically suspend sinks/sources that become idle for too long
# load-module module-suspend-on-idle
```

#### Disale USB wake in BIOS
Boot into the BIOS by pressing the F12 key as the machine turns on. Under `Power Management` >> `USB Wake Support` uncheck both boxes.

Just tried version 4.2. After a two reboots, I finally had my external display working!... for about 3 minutes before my screen started to flicker and finally reverted to the internal display only.

Anyone has more luck?
