Lenovo carbon x1 gen 10 display resolution

English Hardware
1

Hello,

I recently bought a lenovo carbon x1 gen 10 and installed Leap 15.4.

My screen has a nominal resolution of 2880x1800, but the only resolution offered by the system is 1920x1080, and everything looks distorted. Is there any way to change that (a google search did not offer any advice that helped)?

[Other things that currently don’t work are the built-in webcam, and changing the brightness of the screen.]

If anyone has found solutions to these or similar problems, I’d be happy to know… Thanks!

We need to know what’s inside that Lenovo. Input/output from running inxi -CGSaz in a GUI terminal and pasted here using PRE tags should tell us.

Support for Alder Lake is incomplete in 15.4. Choices available to solve include installing a newer kernel, and upgrading to 15.5rc1 or Tumbleweed. Official release for 15.5 will occur in about a month, but it’s pretty close to complete, and very usable, now. I have 20 15.5 installations.

Thank you very much for your help! I installed the newer kernel, and everything seems to be working fine now.
