Last year I found a way to debug what is capturing keyboard shortcuts, by sending X events using xdotool. Now, I have a similar problem where using the Ctrl-Alt-Left in IntelliJ isn't doing anything, so I suspect something is holding on to it.
This time, though, nothing is printing in the logs!
I also tried with other keycombos that were global (such as Win+a, which opens the applications menu), but they produced no log entries either.
What has changed from Ubuntu 17.04 to 18.04 that disables the log output, and how can I enable the log output? There are other entries in the logs, mind you :)
You can try out my debugging steps using this gist, like this:
