--- Comment #17 from Nate Graham  ---
Git commit e5884a1ea6635a35bf8034320fdeecaacb99b5c8 by Nate Graham, on behalf
of Harald Sitter.
Committed on 03/04/2022 at 14:59.
Pushed by ngraham into branch 'master'.

Add some DMI data to about-distro

Now it shows things like the hardware name, manufacturer, and serial number.

Serial number requires an extra click to see so that you don't accidentally
reveal
it when you take a screenshot of the window.
FIXED-IN: 5.25

Harald :In your case where you have a custom build, you probably don't need the
 smbios information. But it does raise the issue of custom bios where you might
like to put your custom info into the bios.

I love this feature.. I requested it around 2 years ago and it is very
useful for getting support.

As it turns out microsoft actually made useful values an oem license
requirement (and is apparently also showing the System Product Name in their
'about' UI in windows 11). So, long term I suppose we'll see the values getting
less crappy. Still, we need a filter list to not show unsuitable values from
non-OEM configurations (e.g. purpose built PCs)

On my system (Lenovo P50 laptop running Fedora 34) the script below will show
whether of not the AC adapter is connected. Not a lot of use if used  on a
desktop. Would be nice to see if it works on other distros.  Another source for
battery information can be found in "/sys/class/power_supply/BAT0"

--- Comment #9 from Brian Kaye  ---
On my system (Fedora 34) the directory " /sys/devices/virtual/dmi/id" contains
much of the system information that might be displayed in kinfocenter. Some
items like the serial number need authorization. The  little script below
displays the contents. Some info is probably not useful. Other systems my have
the info in different locations. So maybe there is no need to run the dmidecode
command. There is a "power" subdirectory but I am not sure of the contents yet.

DIR="/sys/devices/virtual/dmi/id/*"
for i in ${DIR}; do  if ! [ -d $i ]; then echo -ne ${i} "\t"; cat ${i}; fi;
done

In addition to the dmidecode stuff it would be nice to have some basic power

Created attachment 141540

proof of concept patch

I've attached a proof of concept I made the other night. Someone would need to
figure out heuristics to eliminate nonesense values though, which does first
need a list of potential nonesense.

Looks like this on my system https://i.imgur.com/NRx1gKO.png

"Just". That is the "other option" I was talking about.

- we need a kauth helper
- we need heuristics to filter the bogus data out. nobody will be happy with an
entry saying "System Product Name" or "To be filled by O.E.M."

dmidecode does sport a --string argument that allows us to query most/all of
the interesting fields, so, calling the binary isn't the problem (if we ignore
kauth for the moment, cause it is only boilerplate anyway). coming up with the
heuristics will be the tricky bit. all those fields are free form. OEM/ODMs can
put whatever nonesense in there

Could we just dump the output of `dmidecode | grep -A9 '^System Information'`
into the current About This System KCM? I suppose we would need to do some
parsing to separate the labels from the data and stick it into a Formlayout
properly, yeah.

I wonder, I wonder... maybe we should just dump the dmidecode output in a text
KCM. It'd be fairly cheap to do and maintain that way.

The other option would be to feed selective data into the about system kcm. BUT
that is probably fairly costly from a code POV since we need a whole bunch of
heuristics to determine if a given field is indeed useful (e.g. on any device
that isn't from one of the big computer OEMs any number of the fields may not
be filled which usually means they are filled with placeholder garbage that we
need to manually filter out). Smaller ODMs in particular also fail to fill
fields properly at times.

e.g. my system is custom built so I have

System Information
Manufacturer: System manufacturer
Product Name: System Product Name
Version: System Version
Serial Number: System Serial Number
Wake-up Type: Power Switch
SKU Number: SKU
Family: To be filled by O.E.M.
