Re: Thinkpad X1 Xtreme gen 2 adjust screen brightness not working

They promised a fix on the end of this week. They said it on the P1 gen2 thread. Don't know why they won't inform X1 users though.

They released a fixed driver, you can download it from here: https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/P1-Gen2-brightness-control-not-working/m-p/4598199#M85292

 

I downloaded it, installed and my brightness adjust works now. The file is almost 200mb so it takes a while to download.

 

EDIT. Before installing, if you have been using Discrete graphics from BIOS, you might need to change back to Hybrid graphics in BIOS otherwise the installation might not work.

I have installed the latest driver and still can not adjust brightness. Are there any other things that I should look at to ensure I'm fully up to date ?

Re:Thinkpad X1 Xtreme gen 2 adjust screen brightness not working

I just received my new X1 Extreme (March 23) and at first, the screen bightness adjustment worked. Then the magical automatic update happened a couple of days later before i thought of even checking it and of course, the brightness adjutment stopped working as for everyone else here. I tried a couple of the links in this thread and they have been deleted hence, no real solution that I could find anywhere. Any further developments on this? Is there a new, updated driver coming out? This has been an issue for 4 months or more it looks like.

I am having the same problem... I've been using my x1 gen 2 at max brightness for months now because there doesnt seem to be a fix.

Found a solution on this -- worked for me. 

 

Same thing happened with my new P1 Gen 2 -- I tried everything on this Forum (x1 extreme and P series) all to no avail until I did a clean install of windows (Reset) and then was very careful to do all of the Windows updates (outside of Vantage) prior to any driver or Lenovo updates through Vantage or elsewhere, and it worked for me.  My eyes are saved!    

 

Another problem:  I have the OLED screen, (do all of you who also have this issue have OLED?).  When I am passively watching my screen (as in Zoom meetings and Streaming Video) my color and contrast suddenly fade out-- the beauty of the screen goes drab.  It corrects itself when i touch the touchpad, but sometimes this is happening every two minutes and I can't figure out what to do.  It is not the power saver settings, I have it set to 30 minutes and anyway the issue isn't that it darkens and then turns off, it lowers the color and contrast quality.  Anyway having this issue?
