Wifi/brightness not working after transferring to new laptop

[versed fox]

My old laptop broke, so I had all my partitions transferred to a new laptop. It opens and my home screen and everything is normal, even my tabs were saved, but for some reason it won’t connect to wifi, and the brightness slider isn’t there so I can’t change the brightness.

Expected:

there would be a tab labeled “wi-fi” when I opened network settings, and a slider for brightness when I clicked on the battery icon. (See the first photo, ignore the P2P tab)

What happened:

Neither of those two things were there. See photos.

Some more context:

I’ve already tried updating everything, and the driver manager says no additional drivers needed.

What might be important is that the size of the SSD is different between laptops, see photo.

I’ve attached system information below.

Wifi/brightness not working after transferring to new laptop

[analog nebula]

At least concerning screen brightness, this is handled differently at system level depending on the GPU involved. So, a system having an integrated Intel iGPU will sort it differently than a system with an Nvidia GPU, for example (that is, the files specifying (i) max brightness and (ii) current brightness, will be placed differently in /sys depending on this).

Please show the output of

inxi -SMGnxxxz

in the terminal

[versed fox]

Should I have it connected to internet via cable when I do so or does that matter

[fair wasp]

Up to you

[versed fox]

What if they both have intel GPU’s?

[fair wasp]

hmm.... What does

cat /proc/cmdline ; mokutil --sb-state

say?

[versed fox]

Interesting, gpu is listed as n/a

[versed fox]

“Unrecognized option ‘--sb-state’”

[cinder holly]

mokutil --sb

[versed fox]

I might’ve misunderstood what you wanted me to do ngl

[fair wasp]

and cat /proc/cmdline ?

@versed fox

[fair wasp]

Install kernel 6.17, remove the "acpi_osi" kernel parameter, then send a new

inxi -SMGnxxxz

here please after a reboot

[versed fox]

Does it matter which one of these I pick?

[cinder holly]

6.17.0-35

[versed fox]

Also, how do I remove the acpi_osi kernel parameter?

[fair wasp]

How did you got it in there in the first place?

[cinder holly]

xed admin:///etc/default/grub

[versed fox]

No idea lol

[fair wasp]

Or in settings - system administration

[versed fox]

Either I’m blind or I don’t see it in there

[fair wasp]

Below quiet splash

[versed fox]

Well ig I see acpi_osi = linux

Do I just delete that line or?

[fair wasp]

Just the word, leave empty quotes ""

[versed fox]

K

[fair wasp]

Then save the file, close the editor and type

sudo update-grub

[versed fox]

YES

IT’S WORKING NOW, THANK Y’ALL SO MUCH
