Interface Freezing at Beginning of Text Input

[dragonfly41]

There is one tool I am using right now (as I write) for an entirely different purpose to automate interaction with a tool chain of multiple applications. That is emulating user interface. This venerable tool is Actiona in the repo.

sudo apt install actiona

Now if you launch the GUI ..simple launch actiona through [Alt+F2] .. you can use this to monitor interactions with keyboard and dump to console various data.

Thus to start you off drag "Key Condition" widget to central panel .

In the Key Condition widget you can look for a particular key or multiple keys and execute an action or Call Procedure.

You will need the Loop widget to keep monitoring the Key Condition.

This might give insights into what is occurring when defined "Key Conditions" are met. Observing key operations.

You will also need Console widget to log events.

I recommend bulding Procedures to call.

I write my code in external Sublime Text editor since the Actiona internal code editor uses tiny fonts.

This may not answer your question about why you have this change but it will give more insights into what is going on. Note that you can also call Command widget.

Another tip:

The description of your case I researched as "key stuttering" and this opens up a further can of worms.

https://askubuntu.com/questions/1404...-04-stuttering

Some users have reported stuttering issues on Ubuntu 22.04 with Wayland. Try switching to Xorg if you're currently using Wayland, as this could potentially resolve the issue. You can do this by logging out, clicking the gear icon on the login screen, and selecting an Xorg session before logging back in. I did suggest earlier that you try different sessions (switch out of Wayland) .

But nevertheless as a separate line of attack Actiona can still be used to monitor UP and ENTER (or other) keys.

I will take a look at that. Thank you.

I was using X.Org, but following your suggestion, I've switch to Wayland. In the ~24 hours since, I have had no instances of my reported problem.

That said, I've had a slightly different problem under Wayland -- if I haven't interacted with my computer for a while, I sometimes get a one or two seconds of freeze/stuttering after I move the mouse again, and I've also seen a couple of instances of a similar effect when I open the workspace overview. However, this is a much better situation than the issue with text input, so this is certainly a step up. Even if I don't get any further, I can tolerate this at least.

I might also add, that I have the seconds shown on my top-bar clock, which is why I know that it's the interface itself freezing. I previously forgot that this isn't part of the default display.

Edit: Ps, I have an AMD graphics card.

This link which I found for a different reason explains how to install tasksel and switch between desktop sessions. Might be a useful experiment to try different modes.

I continue my own usage of Actiona for desktop orchestration.

P.S. also xdotool must be mentioned.

Just an update on this: I've been using Wayland instead of X11 since my last post, and have had a close to perfect experience, just very occasional stuttering when I open the workspace overview or move the mouse for the first time in a while. I'm telling you this because I don't want to disrespect the time you've spent advising me thus far. I do intend to go back to X11 and try the various tools you suggest, but I've been too busy recently to justify doing so, so it'll have to wait until I have more free time.

Apparently Actiona (which interacts with user interface) does not work in Wayland (or so I read).
Something to do with Wayland security policy since it can be risky if rogue scripts slip through. But I intend to stay with X11. Actiona is a key tool in my toolkit allowing interactions between applications and GUI's. Regarding time for experiments I am just returning to a post I penned elsewhere some three years ago. Tempus fugit.
