As per title.
It is my intention, at some point, to do a full write-up type of tutorial on this. But, work commitments at the moment are making that difficult. So, for the moment, I have simply done a start to finish video of how to install everything. It's slightly messy in places where I have had to go on the internet to figure something out. But, perhaps that is all to the good since it shows you how to get round problems as they arise. The whole video is about an hour long. So, there's a fair bit to get through. But, as I said, it is a complete start to finish video diary of how to do this. So, there should be everything you need.
I should say, here, there is no point whatsoever in doing this if you have a reasonably powerful machine and I would always, under such circumstances, recommend installing Ubuntu Mate. However, if you have an old or very weak machine, it is a very good solution.
My reason for doing this is due to the "updating" OF LXDE to LXQT. At some point, perhaps, LXQT will not be as flaky as it currently is. Also, its devs may eventually be able to bring its RAM consumption down to that of LXDE. But, for now, that is most certainly not the case. Or, at least, certainly not in Lubuntu 17.10.
In any event, although LXDE is a very nice, lightweight OS, it has always had a truly awful main menu in terms of the facility to edit or customize it. So, in that respect, I have always been slightly motivated to find a better alternative and the advent of LXQT has just forced my hand, that's all.
The system in the video comprises of:
Slim login manager
Caja file manager
Nitrogen wallpaper manager.
Wicd network manager
There are a few other things, but they will be apparent in the video
I have also made a short second video showing how to apply Ambiant theming across the system
When fully finished and freshly logged in, it stands at about 185M on the RAM. Which is pretty good in comparison to LXDE.
It does not have desktop management (for desktop icons etc). But, that can be easily achieved by installing PCManFM instead of Caja and using PCManFM as the desktop manager. In which case it comes in around 200M on the RAM. Which is around the same, or only very slightly higher than LXDE.
