<div>Hey Jonathan,</div>
<div>Unfortunately I did not test it for a long time (last
time was around 5.15), and don't really have the
possibility now because I'm away from home.</div>
<div><b>If I remember correctly,</b> back then I had a few
instances when the startup of plasma (during the
splashscreen) was quite longer due to retries of the DDC
communication (of course this will not happen if the user
does not have ddcutil itself installed). As I understand
it, this is due to the architecture of Powerdevil, which
assumes the monitors are a fixed configuration as far as
brightness is concerned: backends are queried at startup
and never refreshed. This is why enumeration has to happen
during startup of plasma, and one would have to restart
powerdevil when connecting a new DDC capable monitor</div>
<div><br>
</div>
<div>Thinking back I wonder if a plasmoid would have been a
better way, enabling to have the enumeration done after
startup is finished, and making it easier to have a
"refresh" button, and would still allow to have both an
integrated screen (laptop) and external (for now the
backends in powerdevil are exclusive).<br>
</div>
<div><br>
</div>
<div>Considering this is my first contribution and I am not
sure of the quality, I think some testing from more
experienced devs would be required. I haven't heard much
so far.</div>

<div>Cheers,</div>
