2nd monitor with VGA-DVI adaptor recognised but no signal detected

I am using Ubuntu 18.04. Graphics: AMD Rv710.



The first monitor connected via HDMI works fine, however, the second monitor connected via VGA-DVI does not.



Screenshot below shows that the second monitor is connected:
Monitor is detected



I have tried changing the input type (only 2 options are given; VGA and D-Sub, neither of which work).
When the cable is unplugged the monitor says cable unplugged however it states no signal detected when it is plugged back in.



Are there any other tests that I can do to try and solve the problem?
Thank you.



Edit: I can also move my mouse over to the other side as if the display should be working.



Adaptor that I am using: adapter






18.04 multiple-monitors display

  • 1. Are you sure that your DVI output has DVI-A? Some cards has DVI-D only so you can't use a converter. 2. If yes, how do you connect them? If you use DVI cable and a DVI to VGA dumb converter, then it won't work, because DVI cable has no DVI-A pins.

  • @AlvinLiang please see edited post for the picture of the adaptor. It is a VGA cable but plugged into the DVI adaptor which is plugged into the PC

  • The port that the adaptor is plugged into seems to be DVI-I

  • Ok so it's not connector type issue.

How to change which sound is reproduced for terminal bell?

Image
3 Recently upgrade to 18.10 from 18.04, and using the terminal is becoming annoying: the new alert sound is a drip ( /usr/share/sounds/gnome/default/alerts/drip.ogg ), and the previous one is still located at ( /usr/share/sounds/ubuntu/stereo/bell.ogg ). My issue is that at the gnome-terminal, when autocompleting or pressing left BOTH sounds are reproduced, at the same time. I want to just have ubuntu/stereo/bell.ogg active, not both . At the moment I have been only able to reduce the volume of the alerts (but still both are played), or turn the alerts down (but I dislike both "solutions"). gnome-terminal 18.10 teminal-bell share | improve this question ...

Can I use Tabulator js library in my java Spring + Thymeleaf project?

0 I want to add Tabulator js to my java project. I added tabulator.min.js, tabulator.min.css to resources folder.

Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

Image
up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title. I would also like to remove the large "0" in the contents title. Any help appreciated, as always. documentclass[11pt,a4paper]{book} % Packages[![enter image description here][1]][1] usepackage[left=3.5cm, right=3.5cm, top=4.3cm, bottom=4.25cm]{geometry} usepackage[utf8]{inputenc} usepackage{libertine} usepackage[libertine]{newtx...
