Hello, here is the LUA code.
I needed a button to switch the CPU frequency between power saving and performance modes. So, the code first checks if the panel is running in Windows or in Linux/OS X, then calls the external script.
You can find the actual scripts in my panel distribution, at http://blog.magnolo.com/pianoteq-touch-panel/

set_governor = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)
	if value==0 then
		governor="powersave"
	else
		governor="performance"
	end
	if package.config:sub(1,1) == '\\' then -- windows
		os.execute( "%UserProfile%\\set_governor.bat "..governor)
	else -- OSX and Linux
		os.execute( "~/set_governor.sh "..governor)
	end
end

By the way, your guide was very useful to understand how to begin with Ctrlr, thank you very much!

Self-answer: Yes, it is possible, using LUA. It was not so obvoius to me. 🙂

I tried the 5.3.178 binary with the new option and it works all right; I noticed that the “add resource” dialog still uses zenity but it works even without the KDE_FULL_SESSION variable. Even the “open panel” dialog now works with zenity.
Anyway, I haven’t experienced any freeze with this build, so the problem seems solved, thank you very much!

I still have occasional program freezes on file dialog open (also when trying to add a resource). I tried to set “Use OS native dialog windows” in preferences but nothing changes.
The only workaround is to reboot the computer until you get lucky and the dialog box finally opens…

These might be useful for diagnosing:

update: if I do
export KDE_FULL_SESSION=true
before the first launch of Ctrlr it works. Otherwise, after Ctrlr is launched without that variable set, subsequent launches won’t work, until the pc is rebooted.

I have the same problem on Lubuntu 15.10 (LXDE/Openbox): Ctrlr freezes on panel open/save.
Is there any workaround?
