Waybar does not start on every launch

[gorillamoe]

IDK if this is a just a problem with my configuration:

• waybar
• sway

or if this an issue in general that can be circumvented somehow.. I tried to search in the already existing issues, but did not find a relevant one..

Like every 2 out of 3 attempts to load waybar (on boot or on reloading with super + shift + c) the waybar will not load at all.. I need to releoad several times to get it up and running..

I freshly migrated to sway and wayland from i3 and went through like a million hoops to get screensharing, screenshotting, filepickers from browsers and keyring unlock on successfull login to work somehow. Maybe I messed someting up on that way.

Any help appreciated.

Why did you move from i3 and xorg?

I think that wayland is the future and I don't want to be late to the party :see_no_evil:

I don't think you have to justify moving ;)

I might be wrong, but I also don't really think it's the config as such, due to the intermittent nature of your issue. The first thing I'd probably do is to look into the log output from the session. Are you capturing any log output?

[gorillamoe]

Hey, I started sway with capturing all outputs and got this, when waybar did not show up:

The touchegg logs are just noise I guess. This must be some kind of race-condtition with my setup I guess, because waybar does show up sometimes and when it does, I get no errors of waybar at all :shrug:

[RobertMueller2]

OK, so there is some error happening. But ideally, we should see what it is, rather than causing an unhandled exception. This sounds a bit like #1451.

I know that one was a long time ago, but in your log waybar also complains about sway/scratchpad not being found, which was also added quite a while ago.

Which version of waybar are you using?

[gorillamoe]

I'm on v0.9.9 which seems to be like 2y old :see_no_evil:

Pop OS seems to be way behind :-1:

Maybe I should switch to the latest Ubuntu and see if a newer version of waybar fixes it?!

[RobertMueller2]

It might or not address the underlying issue, but if it does not, at least you should get an actual error message. The PR mentioned above is included in 0.9.10, so that explains why you just get an unhandled exception here.

[gorillamoe]

I did a complete fresh install with my current setup (dotfiles and setup script) and on the current Ubuntu 24.04 waybar always loads. So, my bad, I was simply using outdated software. Sorry for binding your ressources @RobertMueller2 :1st_place_medal:

[RobertMueller2]

No problem at all, good to hear the issue is solved.
