Anybody having issues with brightness control on Yoga 920. It was fine until recently. Now when you increase or decrease, brightness bar goes up or down, but no change in the actual brightness.
Anybody else having this issue? From windows update, I don't see any recent driver updates.

When I reversed the intel display drivers, it worked for couple of days. Now the brightness doesn't change with function keys.
If you tried to increase or decrease using buttons, it goes to default 20% brighness or so. After that buttons don't work. Screen does show brighness bar, but no change. You can use the mouse to drag the brighness up and down to make it work.
Anybody else having this issue?

This seems to have worked for me: https://zitseng.com/archives/17388
Basically get the latest Intel UHD Graphics 620 drivers and then making sure Windows Update doesn't try to undo it.
