Kernel update help.

I attempted to install the displaylink driver to use the d3100 dock.  But it said I had to upgrade the kernel.  So I did.  But it gave an error about wrong module and then when I rebooted it just goes to a black screen with nothing, no cursor or anything.  should we not be using the generic image from ubuntu on the developer edition?  I'm restoring from a backup and giving it another go.

    Honestly man, the Dell OEM Ubuntu is garbage.  It has kernel 3.13, and the current is 3.19.  For someone who isn't experienced with kernel upgrades, you might want to consider flashing to a stable Ubuntu release.  I made a post a couple days ago with my step by step flashing process, since I was so fed up with how Dell built their OS.


    Plus their recovery app is garbage too.  If there's anything you want to preserve, i would suggest installing Deja Dupe to backup your /home/ config.


    A clean, stable install with a nice fresh kernel does wonders.

    I tried to install the DisplayLink driver on Ubuntu 14.04, but it said my kernel was too old.  So I used the built-in upgrade tool to 15.04, which worked effortlessly.

    At this point, the D3100 dock worked, but the mouse pointer flickered at 2-5 Hz.  After a few days, I decided to see if Ubuntu 15.10 would be an improvement.  It was!  No more flicker!

    If you are considering the D3100 monitor dock, it works very will with Ubuntu 15.10 and the new DisplayLink driver. Wahoo!

    P.S.  This is with a 2014 Dell XPS 13. YMMV.

    P.P.S.  I am running one monitor on the built-in Mini-DisplayPort and a second monitor using the D3100. The laptop build-in display is also running.  Depending on load, the CPU usage is between 50-100% of one cpu (out of 4 total).  So, the total average cpu load is around 12-25%.   Unless you are staring at the performance monitoring tool all day, you will never notice this.

    Where did you get the display-driver working with kernel 4.2 ?

    Driver is from here:   http://www.displaylink.com/downloads/ubuntu.php

    Just used the build-in Software Updater to go from 14.04 -> 15.04 -> 15.10 (2 upgrade steps)

    When I bought the XPS 13 in March 2014, it came with Ubuntu 12.04 LTS.  I tried to do the built-in upgrade to 14.04 but it crashed and left the computer unusable.

    I then got a USB drive with 14.04 and started the live desktop.  A first attempt to install with full features enabled also crashed.  A second attempt to install from the USB live desktop with minimal features worked perfectly.  I have been using it with that 14.04 LTS install for a year now.

    Keep in mind that I have a 2014 model, not 2015 - there may be some differences (WiFi card? Other?). However, if the built-in upgrade doesn't work for you, you may have better luck (as I did) doing a clean install to either 15.04 or 15.10.

    As always, please do a full backup before ANY operating system upgrade!

    Your upgrade might be the explanation. I did a new 15.10 installation and couldn't install the displaylink driver as it don't support kernel 4.2

    This forum s/w seems be mangling the link.

    "www.displaylink.com/downloads/ubuntu.php"

    "www.displaylink.com/downloads" - then click the Ubuntu symbol
