Fix serval keyboard backlights #36

Closed withinboredom closed 3 years ago

withinboredom commented 5 years ago

I maintain https://github.com/withinboredom/system-76-keyboards, and have a Serval. Anyway, about 6 months ago, it stopped working which coincided with a firmware update. I was sad because I thought it was the firmware update.

Tonight I decided to try and discover if I could get them back. I stumbled across this repo and then went through the history to try and discover what happened; plus my dmi table. Here's the output from dmidecode:

# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 3.1.1 present.

End Of Table

You will note that the bios vendor is not System76, but American Megatrends (so it might be that firmware update afterall :thinking:). Anyway, it fails the check in DMI_TABLE_LEGACY, I changed it to DMI_TABLE and the module actually gets loaded and everything works again.

Hello, just checking in here...

mliudev commented 4 years ago

I have a servalWS and this fixes my keyboard backlight detection in Arch Linux.

tleydxdy commented 3 years ago

galp3 needs this fix as well, see https://github.com/pop-os/system76-dkms/issues/45 I modified the corresponding line for galp3 and now it loads fine

mliudev commented 3 years ago

Ping?

withinboredom commented 3 years ago

It occurred to me after running into a similar issue of no one merging a PR on another project... @jackpot51, you are aware that a repo owner has to merge it in right? I can't do that.

jackpot51 commented 3 years ago

@withinboredom yes... I am waiting for @pop-os/quality-assurance approval still

If all tests pass from QA, I approve

leviport commented 3 years ago

Apologies on this one dragging on for so long. Our serw11 lab unit had a GPU failure just a few months before this PR was opened, so we haven't had the hardware to test this. I was planning on waiting until it was fixed, but we've been unable to find a replacement GPU, and my hope of ever finding one is pretty much gone. What I'd like to do is ask everyone who tested this PR on their own serw11 to give me a :+1: on this comment. If the number reassures me, I will bypass standard testing policy and approve it without my own testing.

withinboredom commented 3 years ago

@leviport fwiw, most people probably aren't experiencing any issues with this module not being loaded. You'd only notice you have an issue if you tried hooking into the keyboard backlights. Also, I think it might affect power consumption (I don't remember all the details of this kernel module).

I don't know all the ins-and-outs of things (or if this is even doable), but it might be easier to just push a firmware update that sets the bios vendor to System76 instead of American MegaTrends. It seems a lot less riskier to do it that way IMHO.

If there's some way to downgrade to a previous firmware, I can try that on my machine and see if the previous vendor was System76 as well (just to double-check that that is the issue).

tleydxdy commented 3 years ago

I just wanted to point out the current patch doesn't have the galp3 fix. just in case

leviport commented 3 years ago

I got my serw11 back, so I'll review this soon.

leviport commented 3 years ago

Update: my serw11 started misbehaving again (unrelated to this PR, of course). Sorry, but I have to figure out what its problem is before I can finish testing this PR.

It does seem like we're one of the few people with this issue that cares about setting the keyboard backlight through a script. I was able to get this working by compiling your changes, but it's a hassle because I have to do it every time Arch updates the kernel.
