Notifications cause lags [SOLVED]

baron-digit · 2020-11-08 07:26:42

Hi there,

Kernel: 5.9.6-arch1-1
CPU: 11th Gen Intel i7-1165G7 (8) @ 4.700GHz
GPU: Intel UHD Graphics
using
- BSPWM
- PICOM

I have two questions actually:
1. How do I activate notification daemons, eg. xfce4-notifyd. Honestly, I dont get it how it works with d.bus. (so notify-send isn't working)
2. I have heavy lags for popups on 2 of my machines. (e.g. Thunderbird) is this related?

Thanks in advance for your support.

BR

1. you run the service with your startup scripts or the bspwm config
2. probably, dbus has a 25 second timeout. But "heavy lags" is a bit unspecific.

To 1: Ok I'll check this out.

To 2: With lags I mean that, for instance thunderbird or discord" is not acceessable and the window freezes.
It happens usually when a popup notification appears. In regard of timing, I haven't checked it but it could be within the 25 seconds.

Would it make sense to share some logs? (not sure which one could help here)

(Sorry for this questions, but I'm still learning Linux, and I transitioned from Mac beginning of this year actually.)

Install and run https://www.archlinux.org/packages/comm … _64/dunst/ and see whether the lags remain.
If you use startx/xinit to launch the session, be sure to read the last link in my signature (you could lack a session bus)

What I figured out so far. With xfce4-notify the notfication (at least for thunderbird) is super quick!
No lag at all!

Now I have to autostart the daemon and I think this is it.
What I still struggled with was to use it with dbus, but I'll check this now.

Btw.: Honestly, I use sddm not startx.

Seth, thanks for your suggestions! It's still a steep learning curve, and I'll have to learn more about the basic processes for linux - I guess this will help me a lot.

EDIT: Also dunst works smoothly, but I'll check your .xinit link later the day.

Then the xinitrc concerns don't apply to you.

dbus is just a way of IPC (inter process communication) - the only bit here that might be of further interest is socket activation (you can make it so that trying to call a certain interface will automatically launch a process that provides it) but that's not necessary.

Clients should™ not use synchronous dbus calls in the GUI thread (because that will block it…) but there's nothing a user could do about this.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
