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.

Running:
swaymsg for_window "[app_id=mpv] opacity 0.5"
Works as expected on my end, are you missing just executing
for_window
?Note, you can also add multiple rules in the same execution, e.g.
Also, note that
app_id
of LibreWolf is capitalized in that manner. You can get that information [app_id, shell etc] by runningswaymsg -t get_tree
I guess I should have written the post a bit more clearly. I’ve got the
for_window
part, it’s just that after I set the opacity for all windowsapp_id=.*
, the following lines of the config cannot override that for the specific windows I want different opacities for.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.
