I've just installed a fresh Ubuntu 18.04.1 LTS system, and installed ScreenConnect. It is not showing the screen fully, in that the dock is not visible, and the bottom left "applications" button is not visible either. After a short period, ScreenConnect fails. this was with 6.6, so I updated to the latest SC 6.7 to see if it was already resolved, but still getting the screen issues. Indeed, I note that the nicely displayed window shadows are black on the ScreenConnect display. And while I can click on the dock, despite it not being visible, I don't get to see the result on the display - presumably it is some sort of layer that is not being captured. 6.7 hasn't complained about Java crashes, but it is not usable either.

Given it is a fresh Ubuntu, I don't think it is my system. Is there an easy solution?

No response? Or should I report this as a bug some other way? This is an out of the box mainstream OS that is failing to work with ScreenConnect.

The last time I installed SC on Mint I had to use an older version of Java to get it to work. See here:

Thanks - I don't think that is it, as it did indeed crash a few times with Java errors until I did updates and a Java update was included, and no more errors. This looks much more to do with fancy composition of the displayed image to me, and there is zero on the UI to say "turn off fancy graphics" or anything.

Pity that ScreenConnect doesn't support Linux properly it appears.

What you are describing is exactly what I was seeing in Mint using Java 8. Try openjdk-7u121 as the article suggests, and see if that fixes it. This is very much a case where using the latest/updated version is NOT the answer.

Hmm, thanks. Lots of warnings down that path, and not for the novice. I hate messing about with the core of a system that I just want to use as a tool. I'll see how I get on...

It is a really simple process. The article gives step by step instructions. I think it took me 2 minutes, and I'm not a Linux guy at all.

You say that it is simple, but the first download link is to a page with a load of options that I don't know the right selection for. Software that I've used in the past often came with the java it needed, and that would be a good option to make available for such situations.

I've asked in a separate post for a Linux that will work with ScreenConnect out of the box.

We are seeing the same issue with a fresh install of Ubuntu 18.04.1 LTS. Any resolution to this?

## remove previous verision of screen connect

List Install Packages, find current SC Client Package Name and Remove it

- sudo apt list --installed <enter>

- sudo apt remove screenconnect-bla-bla-bla
<enter>

- You will be prompted to uninstall (y)

## Remove current version of Java

Find all JDK Java Version (> 7 ) and Remove it

- apt list --installed | grep -i jdk

- eg: sudo apt remove openjdk-9-jre
- eg: sudo apt remove openjdk-9-jre-headless


## install Java 7 -- previously downloaded
sudo dpkg -i openjdk-7-* libjpeg62-turbo*

## fix dependancy issues (should install ca-certificates-java & openjdk-11-jre-headless)
sudo apt update
sudo apt install -f

## After JDK7 is installed, use this command to make it the default environment:
sudo update-java-alternatives -s java-1.7.0-openjdk-amd64
### or to pick: sudo update-alternatives --config java

## install screenconnect client -- previously downloaded
sudo dpkg -i ConnectWiseControl.ClientSetup.deb



-- Verify the pc shows in SC list

I have fallen over at this point. How can I previously download it please? The oracle site doesn't allow you to any more. The "software" application is pretty poor / new user friendly!

Thanks for the details, but a source of the right files would be great!

I fixed the problem by installing OpenJDK Java Runtime 11 on our managed guest machines, it's available in the default repos so you can install it with apt-get. The major drawback is that JRE 11 doesn't support Java Web Start anymore, so our technician's computers must keep JRE 8 with IcedTea-Web to keep launching sessions from ConnectWise Control's web interface.
