Intel Xe graphics, windows 10 brightness slider not working with latest drivers

[jlmcr87]

Hi. I have a new Dell Inspiron 7400 laptop with 11 gen intel core processor and intel Xe graphics.

Now i´m using dell intel drivers 27.20.100.8853 and all is working fine. 

But last week, Dell release an update to version 27.20.100.8984 and with this, the brightness slider of windows 10 stop working, and even if you move it, the brightness is always at 100%.

I also have tried with the drivers from the intel website 27.20.100.9126 with the same result.

So it seems that the latest drivers broke something. Reverting back to the driver  27.20.100.8853  make the brightness to work again.

Thanks for your attention.

Since that first release that had the problem came from Dell, you need to be working with Dell regarding the delivery of a fix.

Yeah, but talk to Dell support is like talking to a monkey, the are useless.

Try the latest driver:

Intel® Graphics - Windows® 10 DCH Drivers

Version: 27.20.100.9168 (Latest) Date: 1/20/2021

Thank you very much. This driver works perfectly. So it seems that the buggy drivers are intel´s fault.
