I recently installed Solus on a laptop with an OLED screen. Everything worked fine, except for the brightness control with the keyboard or using Settings > Power > Screen Brightness.
Here is a quick guide on how to get OLED brightness controls working on Solus. I used the icc-brightness program:
https://github.com/udifuchs/icc-brightness
Step 1) Clone icc-brightness or download from Github:
git clone https://github.com/udifuchs/icc-brightness.git
Step 2) Install gcc and liblcms2-devel:
sudo eopkg it -c system.devel
sudo eopkg install liblcms2-devel
Step 3) Navigate into the icc-brightness folder and build it:
sudo make install
Step 4) Add icc-brightness to Budgie autostart:
Navigate to the Budgie Desktop Settings and go to the Autostart panel.
Hit the plus button and choose Add command.
Choose a description and a title.
Use this command: icc-brightness watch
Step 5) Reboot:
Reboot your computer and test the brightness control!
