[Bug] Battery info is not shown in Settings module

[ammarasyad]

Currently on latest ashell version (0.8.0) on CachyOS with Hyprland. Removing and re-adding the Settings module with ashell open crashes ashell (launched from my terminal) with the message:

fish: Job 1, 'ashell &' terminated by signal SIGSEGV (Address boundary error)

I apologize if this was reported beforehand.

Logs doesn't show anything off:

I managed to pinpoint the steps to replicate this, it seems to be missing if I boot with an external monitor attached. Booting without an external monitor displays the battery info, and there is no issue when connecting my external monitor afterwards. Weird.

[romanstingler]

can you please try ashell-git package

Issue seems to be intermittent. After installing it's still gone, but after a restart it's back.

Bit off-topic but now my temps from the SystemInfo module are in Fahrenheit

My battery info is not being shown in the settings module either. Using the ashell-git package on Arch and Hyprland as well. Similarly, my logs appear to show no major issues.

It disappeared again.

Restarting ashell doesn't bring it back.

@ammarasyad can you start ashell from the terminal and see if there is something off

RUST_LOG=ashell::services::upower=trace,ashell::modules::settings::power=trace ashell

and can you try building my branch and see if that works for you

cd /tmp && mkdir debug && cd debug
git clone https://github.com/romanstingler/ashell.git
cd ashell 
git checkout fix/battery
cargo r

Sorry for the late reply, I was unable to reproduce the issue until now. It seems to be intermittent, can't exactly find the right repro steps but it seems to happen more often when booting with an external monitor.

Still nothing out of the ordinary. I'll try your branch.

[ammarasyad]

No luck, still missing. If it helps only a restart fixes the issue.

[romanstingler]

Are you powering the notebook via the monitor?
can you give me like an output of fastfetch or equivalent so I have your system info.

So, let's reiterate,
You use your config from above and when you boot the notebook it happens that the battery icon is sometimes visible and sometimes it isn't.

It is not displayed and then it just disappears, but it is not visible at the time of boot.

can you also try to run this again, I added some debugging logs, maybe we find something in there.
the output is in the terminal if you start ashell via a terminal or /run/user/1000/ashell_rCURRENT.log

cd /tmp && mkdir debug && cd debug
git clone https://github.com/romanstingler/ashell.git
cd ashell 
git checkout fix/battery
cargo r
