SOLVED - Display Brightness not working on 25314

This is one adapter and driver failing to adjust Brightness with 25314.

The same drivers worked fine before the upgrade to 25314.

Tried 4 diffrent drivers including one from 2019, same issue. Same problem also with the Microsoft basic display driver.

This one was downloaded by W.U. just before upgrading to 25314 and it was working fine before the upgrade to 25314.

Same problem with this Driver and Build 25314.

Same problem with this driver too. 🤣

Same problem with this driver from 2019.

The recording tool cannot record the brightness variation, so it is deceiving in this case.

Be that as it may, it's deceiving only to users not affected because you can still see the screen changing.

For those of us affected, it was pretty obvious that brightness wasn't working.

Not obvious at all from the recording.

That is what you are showing on the original post.

The recording does not register the variation in brightness even when it works correctly.

Hi Pauli,

Just started an upgrade to Canary on another laptop, before upgrading to 25314, W.U. downloaded this Graphics driver for the Intel Graphics 620 adapter, Version 30.0.100.9670 dated June/9/2021.

We'll see if it changes after the upgrade.

Could you please check which version you got on your Intel Graphics 630 that is failing the brightness adjustment?

Thanks.

If you mean that long update time then yes. Let's try that.
