Configure LXQt desktop switcher to work across workspaces?

[qajaq]

I installed Lubuntu 18.04 a few months ago, after several years of using Kubuntu in various LTS versions. The LXQt desktop is taking some getting used to, but for the most part, I can learn to use the differences -- except for one. In all KDE environments, when I use the Alt-Tab key to switch from one application to another, I can make the move regardless of which workspace (I usually have seven) I'm in and which one the target application is in. For example, if I'm writing something in a LibreOffice Write file in workspace #1, I can use (in KDE) the Alt-Tab key-combination to switch to Firefox in workspace #2. In the Lubuntu installation, the Alt-Tab combination will only allow me to switch among whatever applications I have open in the same workspace (in this example, workspace #1).

I haven't found a way to switch among applications globally in Lubuntu's LXQt. Is it possible? Or should I try installing a different desktop environment? Or will I have to give up on Lubuntu if I want this functionality?

Great question, and the answer is not easy to find. Lubuntu uses an .xml file to configure this (and many other things) Here's how to change Alt-Tab to switch between all desktops (workspaces):

You must edit parts of the file ~/home/.config/openbox/lxqt-rc.xml

Find and edit this section in the file to fix Alt-Tab. The line in red needs to be added:



<keybind key="A-Tab">
<action name="NextWindow">
<allDesktops>yes</allDesktops>
<finalactions>
<action name="Focus"/>
<action name="Raise"/>
<action name="Unshade"/>
</finalactions>
</action>
</keybind>


Also do the edit that follows to fix Alt+Shift+Tab:


<keybind key="A-S-Tab">
<action name="PreviousWindow">
<allDesktops>yes</allDesktops>
<finalactions>
<action name="Focus"/>
<action name="Raise"/>
<action name="Unshade"/>
</finalactions>
</action>
</keybind>

Now it's ready to go!

Beautiful! So simple and elegant, for all that it's so obscure. It works a charm -- thank you!
