Linux driver not working after upgrade to 15.10

[reindan]

Similar problem here with Dell D3100...
Have been on 15.04 but after an upgrade to 15.10 it doesn't even detect my external displays.

Tried to reinstall, seems all fine except that the drivers don't load at the end...

sudo ./displaylink-driver-1.0.138.run 
Verifying archive integrity... All good.

Could guys try on Ubuntu 15.10 the following sequence:

sudo ./displaylink-driver-1.0.138.run uninstall
./displaylink-driver-1.0.138.run --keep --noexec
cd displaylink-driver-1.0.138/

### In current directory edit displaylink-installer.sh in your favourite editor ###
Find the following piece of script inside the installer file:

detect_distro()
{
  if which lsb_release >/dev/null; then
    local R=$(lsb_release -d -s)
    echo "Distribution discovered: $R"
    if [ -z "${R##Ubuntu 14.*}" ]; then
      SYSTEMINITDAEMON=upstart
    elif [ -z "${R##Ubuntu 15.04*}" ]; then
      SYSTEMINITDAEMON=systemd
    fi
  else
    echo "WARNING: Unknown distribution, assuming defaults - this may fail." >&2
  fi
}

And change it to:

detect_distro()
{
  if which lsb_release >/dev/null; then
    local R=$(lsb_release -d -s)
    echo "Distribution discovered: $R"
    SYSTEMINITDAEMON=systemd
  fi
}

And then run:

sudo ./displaylink-installer.sh install

Sorry - but the proposed script changes didn't give any visible results - for me it's still the same installation response as Reindan got and no recognition of ext. display.

I have tried ones more and have used nautilus to find "displaylink" files. Before installation every things is ok. The installer file have the proposed script, but after installation I find more installer scripts and some of them are with the original and non changed wording. I think the .run file might be the problem.

Ah.. I have reviewed my suggestion and discovered copy-paste mistake. It's now corrected. After modifying displaylink-installer.sh script should be run instead of the original .run file.

The intention of the patching the install script is to force it to create systemd daemon service. The install should print as one of the last output:

Starting DLM systemd service

And you should see /usr/lib/displaylink/DisplayLinkManager among running processes, which you can look up using e.g. htop.

Following your proposal this is the response I get in terminal:

Now I'm up running. I used the .run file and installed displaylink, then I copied the dir. "displaylink" from usr/lib to an USB-stick. Uninstalled displaylink and made a reboot. Kopied the "displaylink dir. from the USB-stick to usr/lib and installed displaylink with the modified installer.sh

And it worked. The response by the installation in the terminal was the following:

I have tested the modified script, it runs well now!

Although it seems to have a little bit of delay, still bearable
