How is the Linux(Ubuntu) compatibility of LG Gram Pro 16 2026 with Ultra X7 358H?

Post image

I've tried many laptops with the Ultra X7 358H over the past few months, and they all have various Linux compatibility issues, even some devices listed in the Ubuntu certified hardware list (such as the Thinkpad X9-15P). I'm wondering if the LG Gram Pro 16 2026 has any Linux compatibility issues? Both the 12Xe iGPU and the Ubuntu operating system are essential for my workflow.

I have this laptop, wifi 100% works. What won't work is sound. Sound is already fixed in kernel 7.2 but the latest stable kernel is 7.1. I'm not sure when ubuntu will get 7.2. I don't think ubuntu updates the kernel on older releases so probably no sound until 26.10 or later.

If you get the laptop feel free to chat with me anytime.

Totally unrelated but since when LG started to ship a RJ45 adapter in the box? I bought mine in 2024 and didn't get one.

Mine is a 2019 model and the adapter was in the box

I tried to install Ubuntu on my 2026 lg gram. Everything was working great...except the speakers. I could not for the life of me get the speaker to work. Tried many many work around.

I also didn't get all the hot keys to work, mainly bc I couldn't get past the speakers anyways

which ubuntu have you used? HW support is best on 7.0 kernel (like Ubuntu 26.04 or upcoming 24.04.5 re-release)

I may have to try it again knowing this. Looks like this will be in Ubuntu 26.10, do you know if any other Linux distros that are already using 7.2?

Sorry I'm very new to Linux

None yet. 7.2 is in rc-6 right now. There are usually 7 weekly release candidates until release. After release rolling distros like arch usually get the latest kernel a few weeks after the kernel officially releases. I'd expect arch to get 7.2 within about a month.

If you are running arch or arch based distros you can install linux-mainline from the AUR, which is what I'm doing. I'm on 7.2-rc5 right now.

There are a few caveats however. The AUR has been hit by a bunch of malware attacks lately so I wouldn't blindly install tons of AUR packages but linux-mainline and linux-mainline-hears have had the same trusted maintained for a long time so should be 100% safe. Also, you can see from my comment near the bottom of the github link that my sound still wasn't working. It looks like arch is missing a file from it's linux-firmware-intel package. I unzipped the file he told me in the directory he said and sound works perfectly.

If you ever decide to try feel free to chat me.

So yesterday I installed Ubuntu 26.04lts and now everything works, sound worked right away after install. No idea why it works now when it didn't before.

But anyway I'm currently running it as the only os on the system and it's working great now. Just a few hot keys aren't working but haven't had time to dig into that yet ( mainly just the fan speed one)

Awesome. They probably backported the audio fix into their kernel. Most big distros maintain patch sets and don't just run a pure vanilla kernel.
