configuring a waltop graphic tablet in Ubuntu 18.04

I have a walcom 10.6″ graphic tablet and pen. It works with the 18.04 installed kernel driver. However I would like to program the “hot patches” around the edges of the tablet and to configure the two press buttons on the pen. It would also be helpful to modify the sensitivity of the pen as it too easily highlights and moves text as it is moved over the tablet. In fact it makes using LibreOffice Calc almost impossible.

And this if it helps

I have explored a number of solutions from the web but without success, a simple graphical display within the gnome desktop would be invaluable.

I look forward to suggestions.

Ubuntu 18.04 SSH VPS keeps disconnecting

I have a Virpus VPS that is running Ubuntu 18.04. Since I got it a couple weeks ago, I have been having trouble staying connected via SSH. I am able to connect just fine, but it will seemingly randomly disconnect (at different intervals). After being disconnected, I usually have to wait a minute for it to allow me back in. I’ve used screen to keep my screen session up, and once I get in I can reattach to the screen without issues.

I have tested it on two different networks on two different computers, both running Windows 10. I have tried using Putty, WinSCP, a Python SSH library called paramiko, and Git Bash for Windows. All with the same results. I have tried SSH-ing into different user accounts, but the issue persists. I have even tried on my phone (Android 6) using ConnectBot. No luck.

Putty says: “Network error: Software caused connection abort”

The Virpus support team says my SSH settings are fine and that they were able to keep a connection (on a Linux box) for at least an hour without problem, after which they manually disconnected. In other words, they can’t replicate the problem.

In an attempt to solve the issue, they changed the public IP of the server, but this didn’t fix it. Their next step was to redeploy to another node, which seemed to work for a little bit, but now I’m still having the same issue.

Does anyone have an suggestions? I can post any config info that you ask for, I just don’t know what to post.

Installing Composer for PHP in Debians (Ubuntu 18.04)

In Ubuntu 18.04 I can install and test Composer PHP dependency manager this way:

apt-get update -y apt-get upgrade lamp-server^ -y curl -sS -o composer-setup.php php composer-setup.php --install-dir=/usr/local/bin --filename=composer composer 

This seems to me a bit messy or unstable, like something here could “change tomorrow”.

How would you overcome such a feeling (or shall I say, anxiety)?
