From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Help with swaywm window rules? (lemmy.ml)

submitted 5 months ago by [email protected] to c/[email protected]

Fellas, I'm at my wit's end with this one. I'm trying to set a general rule for window opacity in sway, and then have a few programs excepted from it.

Back on i3 with picom, I could do this pretty easily by setting activeOpacity to 0.9, for example, and then specifying additional opacityRules like this:

"100:class_g = 'mpv'"
"100:class_g = 'Brave-browser'"

Likewise, hyprland's window rules made it pretty easy to override the general opacity rules as well.

I can't seem to get this on sway, though; if I set it up like this:

[app_id=".*"] opacity 0.85

[app_id="brave_browser"] opacity set 1
[app_id="librewolf"] opacity 1

it simply sets everything to 0.85.

Currently, I have this:

[app_id="^(?!mpv$|brave_browser$).*$"] opacity 0.85

[app_id="brave_browser"] opacity set 1
[app_id="mpv"] opacity 1

but it is still exhibiting the same behavior (except mpv also seems to totally disregard any opacity rules whatsoever).

Any help is greatly appreciated---I haven't been able to find anyone else asking or talking about what seems to me like pretty basic functionality.

My guess is that sway checks sets the opacity when the window open, so when the first rule matches (app_id=.*) it skips all others, so maybe try putting the other 2 rules above the first one?

Sorry if my comment is incomprehensible, I've just woken up.
