qubes-i3status

[ayustae]

Qubes OS version (e.g., R3.2):

R3.2

Affected TemplateVMs (e.g., fedora-23, if applicable):

dom0

Using i3 desktop version 4.12

Expected behavior:

Information of the battery on the i3 status bar.

Actual behavior:

No information of the battery on the i3 status bar (besides xfce4-power-manager).

Steps to reproduce the behavior:

Just installed i3 following the steps on the documentation site.

General notes:

I have traced the problem to the file '/usr/bin/qubes-i3status'.

On the definition of the function 'status_bat' the following path is used:
/sys/class/power_suppy/BAT*
Then, the following files are accessed:
'power_now'
'power_full'

It turns out that in my computer 8and maybe in others) those files are called respectively:
'charge_now'
'charge_full'

My laptop is a MSI cx62 6QD

Related issues:

I haven't found any (though I haven't either searched for them too much).

Further information: the directory where the AC adapter information is stored in my computer is not called 'AC' as in the script (in fact, in my case, it is called 'ADP1' instead).

Hmmm... not sure what you're looking at...

AFAICT it uses energy_now and energy_full, and a quick look through the git history does not immediately reveal the use of either power_* or charge_*.

What version are you running, and where did you install it from?

FWIW, this is what I observe on my system:

@bl4ck-h0le it would be helpful if you would provide output of:

[user@dom0 ~]$ find -H /sys/class/power_supply/*

If it's true that Fedora uses different paths for different systems, then we should update the config script and make it more generic. Even though this is meant as a developer's/power user's window manager, and there's no guarantee that the out of the box experience is smooth sailing, we shouldn't ship in a broken state imho. I'll wait for a reply from @bl4ck-h0le and fix it.

@bl4ck-h0le So it turns out this is not Fedora specific and the battery level can be reported in two ways. (I'm assuming that your power_now was a typo and you meant energy_now) I updated the script to take this into account and it should be more robust now. The updated version can be found here: https://github.com/SietsevanderMolen/i3-qubes/blob/qubes-3.2/i3-settings-qubes/qubes-i3status. There's a pull request in QubesOS/qubes-desktop-linux-i3.

Sorry for my long absence, I was in my exam period.

@jpouellet The result for find -H /sys/class/power_supply/* is in the following file:
power.txt

In case it is still useful.
