Lubuntu 18.04 minimal installation does not include high contrast theme

I really like the trend in Ubuntu and derivatives for offering minimal installation in 18.04. Lubuntu offered that option but it still includes a lot of applications that I don't really need, for example it included gnumeric, Abiword, etc. I am hoping that future versions will be more streamlined.

Anyway, I also sometimes use high contrast theme but this is not installed by the default. To fix this do:

sudo apt install gnome-accessibility-themes

Installing QNX SDP 6.6 Linux on Ubuntu 18.04

QNX SDP 6.6 (Software Development Platform) Linux is a 32-bit application but Ubuntu 18.04 is by default a 64-bit OS. To install it on this OS install the following pre-requisite libraries:

sudo apt install libc6:i386 default-jre-headless:i386 libgtk2.0-0:i386 libcanberra-gtk-module:i386 gtk2-engines-murrine:i386 libatk-adaptor:i386

GIMP Portable 2.10.0 browsing of files not working

I haven't used GIMP in while as I didn't have a need for it, was mainly using GIMP 2.8.20 to help document my work. Anyway, tried a new version of GIMP 2.10 today from PortableApps.com and it looks pretty good. The issue is that browsing does not work. It is big inconvenience, I can open files via drag-and-drop, so it is a little workable. The good news is that upgrade is available, go ahead to SourceForge to get the new version. I have upgraded to GIMPPortable_2.10.0-2 and it works like a champ.

Main download location:
Version that I am using that has the fix for browsing:

Screen sharing on minimal installation of Ubuntu 18.04

Ubuntu 18.04 offered a minimalist install. This gets rid of a lot of software that I don't normally use, I really like this new feature. See below for this option during install.

What you pay with this option though (at least in 18.04) is that screen sharing is not working. This is how it looks like trying to configure it.

 Anyway, to get it work install vino, like:
sudo apt install vino
After installing vino, it should look like below. Observe that Screen Sharing option shows up just below computer name.

Additionally, to connect to it from Windows using RealVNC client, you need to disable vino encryption, like:

gsettings set org.gnome.Vino require-encryption false
