The new version of Nyrna no longer works for me

[famellad]

What's expected

Pressing the Pause key pauses the foreground app

What happens

Pressing the Pause key freezes Nyrna

Steps to reproduce

• Open Nyrna
• Switch to the app one wants to pause
• Press the Pause key

Workarounds

I'll just keep using the previous version for the time being

System Info:

OS: Endeavour OS
Kernel: Linux-ck-zen 5.7.2
DE: GNOME 3.36.3
Python: 3.8.3
X.org: 1.20.8

The previous one-file script version of Nyrna worked beautifully when assigning the hotkey through GNOME's setting panel, however this new version with PyGUI not only does not work (it does not pause the foreground application), but even manages to freeze itself, which is kinda funny not gonna lie.

Anyway, here's the terminal output up until the point where it dies, if you need more info let me know!
What I did was open Nyrna on one terminal and on a different terminal I opened GLXGears, and tried to pause that.

Interesting, can you double check you have libwnck3 installed?

Sounds like Endeavour OS is Arch based, so it should be sudo pacman -S libwnck3

[famellad]

It was already installed, the version in my system is 3.36.0

[Merrit]

I tried running Nyrna under Endeavour OS in a VM and I can't reproduce your issue.

Which version of GNOME are you running under - GNOME / Wayland / GNOME Classic?
Did you see if rebooting the system or checking for updates resolved the issue?
The one part I can't replicate is your kernel, is it possible for you to try another and see if it makes a difference?

[famellad]

Running GNOME under X11, did a fresh update (which updated pyqt5) to no avail, then booted the regular Linux kernel, with no luck either.
I must say though this is puzzling (and I feel rather stupid for just noticing this file exists), the nyrna.log file says

2020-06-18 00:09:54,155 - DEBUG - There is no paused_app.pkl, getting active window
2020-06-18 00:09:54,155 - DEBUG - wnck not installed

So I double checked and

Maybe I'm missing a Python binding or something I could install through PIP?

[Merrit]

Please paste the output of pip3 list

I switched the logic over to using xdotool rather than PyGObject or wnck , which should cut down on code complexity, reduce dependencies, and hopefully be more reliable.

Please check if you have xdotool installed with sudo pacman -S xdotool, and then try the new version of Nyrna.
