Hey all,
since there's a new version of LXQt I decided to try and build it with the help of the wonderful LXQt.SlackBuild by duganchen.
Here I'll list the steps needed if someone else wants to try it.

First grab and install all slackware-available dependencies (from SBo or some repo):
- qt5
- kidletime (kde frameworks 5 by alienbob)
- kwindowsystem (kde frameworks 5 by alienbob)
- libconfig
- libfm-extra
- libkscreen (kde frameworks 5 by alienbob)
- libstatgrab
- menu-cache
- muParser
- openbox (optional)
- polkit-qt5 (kde5 dep by alienbob)
- solid (kde frameworks 5 by alienbob)

Then you'll need an extra dependency that I could not find on SBo, so I had to grab the source from the canonical archives and build it myself

- libdbusmenu-qt5 (cmake/make/make install super easy)

Then go download all the latest LXQt sources and put them in a folder of your choice together with the slackbuild of duganchen.
Download and put in this folder also the following files that I wrote to automate the build of all components
- build_all.sh
- build_order.txt

Finally execute as super user the script build_all.sh and it will build and install all packages in the correct order.
The script quality is questionable since i'm not very skilled in bash, so use it carefully and feel free to give me some suggestions/critics to improve it.
The complete build takes less than 10 minutes with my old i5 and the desktop, apart of some little quirks, is a joy to use, feels light and modern. I hope it will get included as an alternative if Pat would choose to skip the new Plasma5.
Enjoy!

Hahaha that's soo much better than my crappy scripts, wish I found it sooner. At least I learnt some bash.

Are you able to launch LxQt after using my SlackBuilds?

(Yes, this is a serious question. I actually haven't done a good job of testing that).

Whoa nice.

Does it work with slackpkgplus?

Thanks.

I don't think so. slackpkg+ works with packages correct? I have only made the SlackBuilds. I don't have anywhere to host packages. That and I need to go through and fine tune a lot of things. LXQt and LXDE are probably done, but everything else needs to be gone through.

I had to steal the xinitrc from somewhere, I think alienbob old packages. Other than that it worked as a charm for all components I listed in the build_order file

Is this still available? I clicked on it and got "You need to sign or sign up before continuing".

Yea. I moved to NotABug: https://notabug.org/SlackDesk/LXQt

I must be missing something but is there a quicker way of setting it up rather than descending into each folder and manually compiling?

I wrote a couple of script to automate the installation at the time.
A precise build order must be followed, otherwise you miss some dependencies.
Unfortunately I can't find them anymore, but you can take a look at it here Building-from-source

EDIT: look in the original post, the scripts are still on pastebin

I've found that with my SlackBuilds, at least, you only get correct-ish behavior if you do the following before starting LxQt:

As how (or whether) I should be building it differently, I skimmed some stuff, including this, and I'm honestly not sure:

Also: you can't set the time or even set LxQt to see the system time as local time instead of GMT. LxQt needs systemd for that:

I tried slack-timedate but it didn't work. So it looks like the best solution is to just remove the clock from the panel.

I was thinking about implementing org.freedesktop.timedate1 on Slackware for a project I'm working on (unrelated to LXQt), didn't know someone had already made one (thanks for the info). I looked at the code and it should work, try to verify with qdbusviewer. I can test it myself when I get the time...
