My friend has a lenovo P500 laptop, and it has a brightness issue. The issue is that the brightness is on like the lowest setting and even though the interface controls register adjustment the brightness will not change. He even tried Xinput commands.
On windows people reported a driver update that made the brightness stick on lowest brightness and not change. Rolling back the drivers would solve it. But on elementary OS, how would one get drivers that would solve this issue?
Or is there another way to solve this issue?
