[Solved] Suspend and brightness scale not working on Lenovo IP 3 15ALC6

[Tol1as]

Hello, I'm new a Linux user.

I installed Mint Cinnamon today in this newly bought laptop (Ryzen 7 5700U/15.6 FHD IPS/8GB/512GB SSD), in dual boot with WIn 10. After installation I ran both the Software and Driver manager and did all upgrades.

Everything went fine, except for a few issues so far:

1) Choosing to suspend and then waking up the laptop results in the keyboard leds turning on and the fans working but the screen won't turn on.
2) Cannot control the monitor's brightness at all. The brightness is maxed out (which really eats at the battery) and using either the laptop shortcut (Fn + F5/F6) or the brightness setting in the battery has no effect, i.e the sliders work but brightness is not decreased (or increased) at all.
3) Every time I boot on Mint I get a message that I should upgrade my display drivers... running the driver manager tells me that my drivers are all up to date.

EDIT

It seems my google-fu wasn't strong enough. All issues were due to the fact that Ryzen 5700U is newer than the current Mint Kernel (5.4.0.96)

All issues were resolved by installing new kernel: Update Manager -> View -> Linux Kernels, then click a version and install. I personally went with the latest 5.13.0-27

Inxi also correctly gives

Device-1: AMD vendor: Lenovo driver: amdgpu v: kernel bus ID: 03:00.0 , where it was saying N/A before. Praise the kernel gods.

Hope this will help someone else in the future.

Hello, Tol1as.

This section in your inxi output illustrates the root cause of your problem:

Graphics:
Device-1: AMD vendor: Lenovo driver: N/A bus ID: 03:00.0
chip ID: 1002:164c
Display: x11 server: X.Org 1.20.13 driver: ati,fbdev
unloaded: modesetting,radeon,vesa resolution: 1920x1080~77Hz
OpenGL: renderer: llvmpipe (LLVM 12.0.0 256 bits) v: 4.5 Mesa 21.0.3
compat-v: 3.1 direct render: Yes

The kernel should load amdgpu, I guess, but it does not load any video module matching your AMD graphics card.
The x11 server should load ati,amdgpu, but it loads ati, fbdev instead. fbdev is too old and not capable of supporting all the features of your video card.
And the culprit will be your old kernel 5.4.0-96-generic, which is older than your machine from 12/13/2021

Solution:
I am pretty confident that the solution offered and implemented in this similar thread, [Solved] My system is currently running without video hardware acceleration., will help you as well.

Curious to learn whether I am right.

Regards,
Karl

P.S.:
Oops, our posts crossed. Rather your Edit and my post crossed and you have solved the problem yourself by switching to a newer kernel series.
Congratulations. Right move.

Yep you were Karl. I found the solution by googling Mint 20.3 Ryzen 5700U, as I remembered reading about the new-ish ryzens causing issues in Linux. Thanks for responding.

As a side jesus, was this installation fast. It took me like an hour and a half to set up almost everything, while it took four++ hours in for the same thing in Win10...
