Could you post the output from the following commands please?

$ python --version

and

$ wmctrl -l | awk '{ if( $2 != "-1") { $3="";  print $0} }'

and

$ wmctrl -d | sed -n -E -e 's/^.*WA: (N\/A|.,. [[:digit:]]+x[[:digit:]]+)  //p'

Thanks!

Fantastic, thanks!

Sorry, I forgot one:

$ python3 --version

[OmarShawky1]

$ python3 --version
Python 3.6.9

I also get the same error.

I have just pushed a change which fixes one instance of getting suck at "Loading..." which I found. Maybe this fixes it for you?

[OmarShawky1]

Nope.

[dflock]

It seems like this command doesn't work on elementaryOS, for some reason:

$ wmctrl -d | sed -n -E -e 's/^.*WA: (N\/A|.,. [[:digit:]]+x[[:digit:]]+)  //p'

This should spit out a list of workspace names, something like this:

$ wmctrl -d | sed -n -E -e 's/^.*WA: (N\/A|.,. [[:digit:]]+x[[:digit:]]+)  //p'

If running that doesn't produce any output, can you please just try this command on its own:

$ wmctrl -d

and paste the output from that?

[OmarShawky1]

I have 2 screens and 2 workspaces which add up to 3.

$ wmctrl -d
0  * DG: 2640x1024  VP: 0,0  WA: 0,30 2640x994  Workspace 1
1  - DG: 2640x1024  VP: N/A  WA: 0,30 2640x994  Workspace 2
2  - DG: 2640x1024  VP: N/A  WA: 0,30 2640x994  Workspace 3

Edit: This solution appears to be working, it uses wmctrrl -l instead if d flag Here is the output sample:

$ wmctrl -l

I have the same problem on Linux Mint 20.3 Xfce

Hi,

fix here is fairly easy, posted pull request #12

In the meantime before author merges pull request, you can check if it works for you by editing the line 62 in $HOME/.local/share/ulauncher/extensions/com.github.dflock.ulauncher-window-switcher/main.py

result = subprocess.run(
            [
-                 "wmctrl -d | sed -n -E -e 's/^.*WA: (N\/A|.,. [[:digit:]]+x[[:digit:]]+)  //p'"
+                 "wmctrl -d | sed -n -E -e 's/^.*WA: (N\/A|.+,.+ [[:digit:]]+x[[:digit:]]+)  //p'"
            ],
            stdout=subprocess.PIPE,
            stderr=subprocess.PIPE,  # equivalent to capture_output=True
            shell=True,
            universal_newlines=True,  # equivalent to text=True
        ).stdout

For me it now works flawlessly:

[OmarShawky1]

@stefanjarina Yes, This solved the entire problem & it worked smooth. Thank you.
