`M-w` bindig hijacked by some applications. #859

Open orencio opened 2 years ago

orencio commented 2 years ago

Some applications hijack M-w binding for some minor modes.

For example, flatpak Spotify application:

$ flatpak list | grep spotify
Spotify com.spotify.Client  1.1.68.632.g2b11de83    stable  system

Launching this application (and switching to other workspace) causes M-w not to be recognized by Scratch buffer, org-mode.

If I press C-h k and the press M-w emacs doesn't detect I've pressed M-w.

This is commented in:

Is there anyway to prevent M-w to be hijacked?

orencio commented 2 years ago

Curious fact is that if I split the Spotify workspace in two windows and in the other window I switch to scratch buffer, then all workspaces attend correctly to M-w binding. Although I unsplit the Spotify workspace to maintain Spotify window alone.

That's weird.

Please, follow the steps in https://unix.stackexchange.com/questions/59141/find-x-org-pointer-grab-owner/62252#62252 or https://unix.stackexchange.com/questions/23164/manipulating-x-key-and-pointer-grabs-on-the-command-line/273198 to check who's grabbing the key.

Hello, I've migrated to emacs 28.1 (Arch Linux) and I get same issue.

I attach Xorg.0.log file with grab info.

At the moment of creating the log, the apps whose was hijacking M-w key was electron (Element and Mattermost), and Spotify:

...

I've probed to specify this and M-w continues hijacked:

(setq exwm-input-prefix-keys
      '(?\C-x
        ?\C-u
        ?\C-h
        ?\M-x
        ?\M-w
        ...
        ))

Regards.
