Bazzite 3.0 New install - GPD Win 4 6800U - Gyro not working

Hi! New user here. Just installed bazzite, almost everything working perfectly apart from external screen not working in desktop mode (not so important) and gyro not working. I have been trying to investigate this last one. Tried removing conf for HHD, rebooting, played with several options of HD to no avail. On a fresh boot, calibration values in Steam show either 0 all of them or some weird numbers, no reaction to movement. Doing a lsmod I found the bmi160 module, shouldn't I have the bmi260 instead? any idea how to troubleshoot this further?
EDIT: this is the dmesg output for the bmi modules
[ 6.300967] bmi160_i2c i2c-BMI0160:00: supply vdd not found, using dummy regulator
[ 6.313653] bmi160_i2c i2c-BMI0160:00: supply vddio not found, using dummy regulator

Try the gyro fix

kikeminchasOP•4/26/24, 1:11 PM

yeah, I followed your guide, thanks a lot by the way. Giro fix installs succesfully but has no effect. The issue is present imediately after a fresh boot in any case. Based on the dmesg output above I think I might have the wrong module installed? Wouldn't I need a module for the bmi260?

Aru•4/26/24, 1:40 PM

Let me double check on my win 4 too

Aru•4/26/24, 1:43 PM

Looks like I might need to update the gyro fix for Bazzite 3.0

kikeminchasOP•4/26/24, 1:55 PM

sorry, I'm maybe getting something wrong but I just checked the code of your fix and I see it's modprob'ing the bm260 modules ... I think the problem is that I don't have these modules ...

Aru•4/26/24, 1:56 PM

Yep, looking more closely, looks like it's definitely something else

Aru•4/26/24, 1:58 PM

So for more context, the win4 actually has a bmi160. My understanding is that due to some id mislabeling on gpd's part, it was misidentifying as a bmi260

Aru•4/26/24, 1:59 PM

I'm assuming maybe there's now an upstream kernel fix for this somewhere

Aru•4/26/24, 1:59 PM

But I'd have to investigate more later, currently traveling

kikeminchasOP•4/26/24, 2:00 PM

no worries, I will do some more googling in the meantime, thanks!

Aru•4/26/24, 2:13 PM

Worst case scenario, temporarily rollback to pre-3.0 Bazzite and pin

kikeminchasOP•4/26/24, 2:27 PM

can I rollback to a previous version even if 3.0 is the first version I installed?

Aru•4/26/24, 2:39 PM

Yep, definitely possible

Aru•4/26/24, 2:39 PM

Check the rollback documentation

Updates, Rollback, and Rebasing on Bazzite

Yes it is true for all of them, however I mostly focus on documentation on the Bazzite image which is why it’s here. Desktop images of Bazzite follow the same automatic update style that the main images follow. However, there’s also the -deck images that do not follow this which is why I wanted to differentiate between them. As for pinning, w...

AAru Check the rollback documentation

It's bmi260 when you get the chip id error

antheas•4/26/24, 2:48 PM

@Kyle Gospo 260 kmod is missing

antheas•4/26/24, 2:48 PM

Make sure if secure boot is on you enrolled the mok key

antheas•4/26/24, 2:48 PM

Or that

Aantheas @Kyle Gospo 260 kmod is missing

Kyle Gospo•4/26/24, 2:48 PM

could have sworn we agreed all the gyro kmods were no longer needed

Kyle Gospo•4/26/24, 2:48 PM

and they should be removed

kikeminchasOP•4/26/24, 2:48 PM

I'm not using secureboot

antheas•4/26/24, 2:48 PM

160, 323 yes

antheas•4/26/24, 2:48 PM

150 yes

Kyle Gospo•4/26/24, 2:48 PM

I will restore 260 later today

antheas•4/26/24, 2:49 PM

260 no

kikeminchasOP•4/26/24, 2:49 PM

thanks guys, so I won't rollback and just wait for an update, right?

Kkikeminchas thanks guys, so I won't rollback and just wait for an update, right?

Kyle Gospo•4/26/24, 2:49 PM

yup

Kyle Gospo•4/26/24, 2:49 PM

should just start working later on

kikeminchasOP•4/27/24, 10:43 AM

Sorry, just double checking, I got an update this morning. Dmesg still showing the wrong id error for the BMI160 and gyro not working. Updates come via topgrade, right? Anything else I need to do?

Kyle Gospo•4/27/24, 3:26 PM

@antheas I restored 260 like you asked

Kyle Gospo•4/27/24, 3:26 PM

Do you want me to restore all three?

KKyle Gospo Do you want me to restore all three?

antheas•4/27/24, 3:50 PM

No just 260 is out of tree right now

Kyle Gospo•4/27/24, 3:51 PM

Well it's in and seemingly still broken

Kkikeminchas Sorry, just double checking, I got an update this morning. Dmesg still showing t...

antheas•4/27/24, 3:51 PM

So it should work

antheas•4/27/24, 3:51 PM

It should load

kikeminchasOP•4/27/24, 4:29 PM

I will try again later this evening, I updated and tried again this morning but it didn't work. Dmesg gave the same message like in the first message of the thread

Kkikeminchas I will try again later this evening, I updated and tried again this morning but ...

antheas•4/27/24, 4:33 PM

It should

antheas•4/27/24, 4:33 PM

But below it there should be an extra 260 message

Aantheas It should

kikeminchasOP•4/27/24, 7:30 PM

the module is not there I'm afraid, checked again dsmeg output and a 'lsmod | grep bmi' only returns entries related to the 160...

antheas•4/27/24, 7:30 PM

Something went wrong then @Kyle Gospo

Kyle Gospo•4/27/24, 7:37 PM

Like I said, we probably need those modules

Kyle Gospo•4/27/24, 7:37 PM

Bmi160 conflicts and loads incorrectly without the patch

KKyle Gospo Bmi160 conflicts and loads incorrectly without the patch

antheas•4/27/24, 7:54 PM

It doesn't conflict

antheas•4/27/24, 7:54 PM

That's how it is supposed to work

antheas•4/27/24, 7:54 PM

It returns enodev after the chip id check fail

antheas•4/27/24, 7:54 PM

And lets the 260 load

antheas•4/27/24, 7:54 PM

And lets the 260 load

Kyle Gospo•4/27/24, 7:55 PM

Do we know for certain that patch is in fsync 160?
