Tilix: [Feature Request] Blur like Opacity in Tilix / VTE

[alex285]

is that doable?

[gnunn1]

No it is not, Cairo has no blur operator AFAIK.

[alex285]

tata! with elementary's Gala Blur experimental API
https://github.com/elementary/gala/commits/optimized-blur-vala

[gnunn1]

Cool, did you have to change code in Tilix to do it?

[alex285]

@gnunn1 nop! i activated it with DBus! it is Gala feature, that you can enable for each app! if they push it that in their master, i will open an issue to add an Blur switch next to opacity, if someone runs Tilix on elementary!

[gnunn1]

While it's cool please don't bother opening an issue, i don't have any plans to support gala or elementary.

[alex285]

@gnunn1 thats absolutely fine! if they use it on Juno, i can PR it anyway! it is pretty trivial patch! plus it can work with KWin too!

[aviwad]

@alex285 wow! does it cause any major slowdowns? <3 big fan

[alex285]

@GNOME-IS-LIFE it shouldn't, Deepin has already same implementation as the one elementary uses, but we should wait elementary Juno final release first

[aviwad]

@alex285 really? so KDE Plasma just used the same "new" technique Deepin had been doing for years?

[ryu-ketsueki]

@alex285 How do I enable the blur background in Tilix with KWin?

[belozer]

Blur working in KDE Neon 5.13.2 and tilix 1.8.1!!!

[belozer]

@alex285 please try ;)

[ryu-ketsueki]

@belozer how did you do it? I'm running Manjaro with KDE Plasma 5.13.2 and Tilix 1.8.1 here.

[alex285]

@belozer i dont want to spam Tilix Github, but for one time i will :p

[belozer]

@ryu-ketsueki

1. Set opacity in Tilix
   

2. Set Blur in effects
   

[ryu-ketsueki]

@belozer Just did that and KDE still refuses to blur Tilix's background.Perhaps it's something with my GTK theme? I'm using Gnome OSC

[belozer]

@ryu-ketsueki @alex285 Oops. I forgot I have one code in my .zshrc.

if [[ $(ps --no-header -p $PPID -o comm) =~ tilix ]]; then
    for wid in $(xdotool search --pid $PPID); do
        xprop -f _KDE_NET_WM_BLUR_BEHIND_REGION 32c -set _KDE_NET_WM_BLUR_BEHIND_REGION 0 -id $wid; done
fi

Please try.

I mistakenly believed that this is due to the Plasma 5.13.2 :crying_cat_face: ..........

[ryu-ketsueki]

@belozer I'm using fish as my default shell. Is there a code that works for it?

[belozer]

@ryu-ketsueki I don't use fish. But you can try to adapt the code https://axionl.me/2018/01/27/blur-for-terminal/

[belozer]

@ryu-ketsueki

Try in your fish config

set -l ppid (cat /proc/(echo %self)/status | grep PPid | cut -f2)
if string match -r 'tilix' (ps --no-headers -p $ppid -o comm) 1> /dev/null
    for wid in (xdotool search --pid $ppid)
        xprop -f _KDE_NET_WM_BLUR_BEHIND_REGION 32c -set _KDE_NET_WM_BLUR_BEHIND_REGION 0 -id $wid
    end
end

from https://www.reddit.com/r/kde/comments/7szqqk/i_implemented_a_new_blur_effect_in_kde_it/dtsfbbn/

[FFY00]

if test (ps --no-header -p $PPID -o comm) =~ tilix
    for wid in (xdotool search --pid $PPID)
        xprop -f _KDE_NET_WM_BLUR_BEHIND_REGION 32c -set _KDE_NET_WM_BLUR_BEHIND_REGION 0 -id wid
    end
end

should work

[ryu-ketsueki]

@FFY00 @belozer Alright. I tested both and none worked. Here's what might be causing it:
1 - ps --no-header -p $PPID -o comm is not equal to "tilix", but to "fish" in my end.
2 - xdotool search --pid $PPID is not giving an output, not even when I type the command manually with my PPID. (Just installed xdotool from Manjaro Repositories). Because of this, the xprop command won't work, not even manually.
Now I'm trying to use the fish code for blur that appeared for Konsole and Yakuake here as base to work for Tilix. I'll tell you guys if I do any progress;

The code for Konsole and Yakuake is:

if test $DISPLAY
    for ID in (qdbus | grep -E "konsole" | cut -f 2 -d\ )
            xprop -f _KDE_NET_WM_BLUR_BEHIND_REGION 32c -set _KDE_NET_WM_BLUR_BEHIND_REGION 0 -id (qdbus $ID /konsole/MainWindow_1 winId)
    end
    for ID in (qdbus | grep org.kde.yakuake)
            xprop -f _KDE_NET_WM_BLUR_BEHIND_REGION 32c -set _KDE_NET_WM_BLUR_BEHIND_REGION 0 -id (xwininfo -name Yakuake | grep "Yakuake" | sed 's/xwininfo: Window id: //g' | sed 's/"Yakuake"//g')
    end
end

[dougmaitelli]

The code from @belozer works perfectly for me on fish! Thanks

[alex285]

@belozer did you see? :)

[belozer]

@alex285 yes :tada: thanks! ;)

I recommend using the devilspie tool instead of modifying the .zshrc script.

Following is my ~/.devilspie/tilix.ds configuration.

(if (is (application_name) "tilix")
    (begin
        (spawn_async (str "xprop -id " (window_xid) " -f _KDE_NET_WM_BLUR_BEHIND_REGION 32c -set _KDE_NET_WM_BLUR_BEHIND_REGION 0 "))
        (spawn_async (str "xprop -id " (window_xid) " -f _NET_WM_WINDOW_OPACITY 32c -set _NET_WM_WINDOW_OPACITY 0xdfffffff"))
    )
)

And register the devilspie tool to autorun.

[alexschomb]

If the .config/fish/config.fish of @belozer above doesn't work for you, try adding a short pause to the script. That did the trick for me:

set -l ppid (cat /proc/(echo %self)/status | grep PPid | cut -f2)
if string match -r 'tilix' (ps --no-headers -p $ppid -o comm) 1> /dev/null
    sleep 0.01
    for wid in (xdotool search --pid $ppid)
        xprop -f _KDE_NET_WM_BLUR_BEHIND_REGION 32c -set _KDE_NET_WM_BLUR_BEHIND_REGION 0 -id $wid
    end
end

[danielwangksu]

Are those settings only work for KDE?

[ghost]

@ryu-ketsueki @alex285 Oops. I forgot I have one code in my .zshrc.

if [[ $(ps --no-header -p $PPID -o comm) =~ tilix ]]; then
    for wid in $(xdotool search --pid $PPID); do
        xprop -f _KDE_NET_WM_BLUR_BEHIND_REGION 32c -set _KDE_NET_WM_BLUR_BEHIND_REGION 0 -id $wid; done
fi

Please try.

I mistakenly believed that this is due to the Plasma 5.13.2 ..........

Thank, it works in deepin

[Paralusion]

the solution provided by belozer is great, but wasn't quite functioning how i liked; it'd only blur if you opened it twice.
i fixed this by adding a simple sleep function, here's the updated code for if anyone has the same problem

https://hastebin.com/fufiyavaza.bash (github code syntax wasn't really working)

[mykahveli]

@belozer, I have a particular issue. The blur effect goes beyond the window:

Would you mind give me some tips?
