Comment # 15 on bug 1186896 from P

> Hm, I'm confused.  Now you're using which OS and which setup?

Leap 15.2

> Is it about Leap 15.3 kernel + user-land, or still Leap 15.2, or about TW?

Still Leap 15.2. (I don't know what user-land means)

> And is the main problem you're talking about is the brightness, and that's with amdgpu (i.e. without nomodeset), right?

Correct.

Just to remove the confusion about 15.2 vs 15.3, I've just wiped my Leap 15.2
to install Leap 15.3. That should get me aligned with your baseline. And my
current 15.2 setup it not very usable anyway.

Unfortunately, the ISO boot image hangs when starting udev (see attachment:
leap15.3_hangs_at_udev.jpg)
After reading up on the boot params, I was able to boot from the Leap 15.3
stick using "acpi=off". I've tried many boot params, and this one was the only
one I could boot with.

The installation went ok. This comment is just written with the new Leap 15.3

Good news: Brightness and external screen work. So that's very nice.

Bad news: without ACPI I have a single core, no Fn keys and no touchpad and
probably more goodies. So it's still bad I suppose. But it does lead to the
question if we should maintain this bug as is. Please provide direction.

I'm now planning to wipe 15.3 again, repartition my drive and go for a
multiboot config, so that I have a workable environment, but also an
environment I can use to work on this bug.

PS: 
I came across another webshop which also sells my laptop:
https://laptopmetlinux.nl/product/clevo-nl51ru
Surprisingly, they support 9 Linux configurations with this laptop, but
openSUSE is not on the list. This could potentially be related to the udev
issue.

I'd be happy to work on this in any way you suggest. Please bare in mind I need
some time to get me a workable multiboot system. So I might be unavailable for
the next couple of weeks. I'm definitely going to try the list with the 9
distributions.
