Brigthness function key workaround for intel chipsets

[GyHUN95]

Omarchy 3.2.1, The default brigthness binds not controls intel hd chipset and/or standalone aio monitor brigtness. For this OS the standalone monitor's physical buttons work neither.

I saw some workaround for apple and media button context, but here is my quick solution for intel, so it should be used for Lenovo mini pc-s thinkpads and Lenovo AIO monitors.

1.: Install ddcutil
sudo pacman -S ddcutil
2.: Activate the corresponding module
sudo modprobe i2c-dev
3.:Add your user rights
sudo usermod -aG i2c $USER
4.: Check detection
ddcutil detect
The result will be stg. like this:

5.: Try to lower brightness with the newly installed util:
ddcutil setvcp 10 20
6.: Try to rise brightness with the newly installed util
ddcutil setvcp 10 100
If those works, we should rebind it, so for that we have two place, i suggest the second actually due to default config restest/changes yet nowadays..

For the default bindings where the original lines (9 and 10 found):
nvim ~/.local/share/omarchy/default/hypr/bindings/media.conf you should at least comment these:
#bindeld = ,XF86MonBrightnessUp, Brightness up, exec, $osdclient --brightness raise
#bindeld = ,XF86MonBrightnessDown, Brightness down, exec, $osdclient --brightness lower
but you can write the new binds here, or go for the next step...

SOLUTION:
edit the .config/hypr/bindings.conf and add
bind = ,XF86MonBrightnessUp, exec, ddcutil setvcp 10 + 10 --skip-ddc-checks && $osdclient --brightness raise
bind = ,XF86MonBrightnessDown, exec, ddcutil setvcp 10 - 10 --skip-ddc-checks && $osdclient --brightness lower

The --skip part is important for faster response time from the tool.

AFTER THAT IT SHOULD WORK IMMEDIATELY, but if not, try:
hyprctl reload

Note: on some monitor the brigtness percent of the osd always be 0, but the current value can be checked by:
ddcutil getvcp 10 | awk -F'[=,]' '/current value/ {print $2+0}'

If the wrong OSD number triggers you, you should left the && $osdclient --brightness lower/rise visual feedback part of the bindings

P.s. someone give me a feedback, that should I put this on the issues page too or not... 😄

Keep up the good work!
