[ddccontrol-users] a warning on start

[Jerónimo B. M. <jer...@gm...>]

every time i open ddccontrol i get this warning
"Warning!

There is no support for your monitor in the database, but ddccontrol is
using a basic generic profile. Many controls will not be supported, and
some controls may not work as expected.
Please update ddccontrol-db, or, if you are already using the latest
version, please send the output of the following command to
ddc...@li...:

LANG= LC_ALL= ddccontrol -p -c -d

Thank you.
"

so here's the result of such command.
$ LANG= LC_ALL= ddccontrol -p -c -d > ddcc


ddcc2 has some other stuff that got printed to the console.

thanks for your work on this software.
if there's a way to disable this warning i would appreciate it if you could
tell me.

Kind regards,

Hey,

I have an Odyssey G9 monitor. At some point in the last few months my
ability to adjust the brightness using the KDE Plasma-PowerDevil service
stopped working. The slider slides, but the monitor brightness doesn't
adjust.

... so I started Googling, and AI suggested that I try
gddccontrol directly, so I did, and the program prompted me to send you the
output of `LANG= LC_ALL= ddccontrol -p -c -d` so here you go:
