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 [ 6.315550] bmi160_i2c i2c-BMI0160:00: mounting matrix not found: using identity... [ 6.317966] bmi160_i2c i2c-BMI0160:00: Error reading chip id [ 6.319329] bmi160_i2c: probe of i2c-BMI0160:00 failed with error -121

Try the gyro fix

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?

Let me double check on my win 4 too Looks like I might need to update the gyro fix for Bazzite 3.0

kikeminchasβ€’2mo ago
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 ... πŸ€”

Yep, looking more closely, looks like it's definitely something else 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 I'm assuming maybe there's now an upstream kernel fix for this somewhere But I'd have to investigate more later, currently traveling

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

Worst case scenario, temporarily rollback to pre-3.0 Bazzite and pin
kikeminchas
kikeminchasβ€’2mo ago
can I rollback to a previous version even if 3.0 is the first version I installed?
Aru
Aruβ€’2mo ago
Yep, definitely possible 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...

It's bmi260 when you get the chip id error @Kyle Gospo 260 kmod is missing Make sure if secure boot is on you enrolled the mok key Or that

could have sworn we agreed all the gyro kmods were no longer needed and they should be removed

I'm not using secureboot

yup should just start working later on
kikeminchas
kikeminchasβ€’2mo ago
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?

1/4 Lifeβ€’2mo ago
@antheas I restored 260 like you asked Do you want me to restore all three?
antheas
antheasβ€’2mo ago
No just 260 is out of tree right now
1/4 Life
1/4 Lifeβ€’2mo ago
Well it's in and seemingly still broken
antheas
antheasβ€’2mo ago
So it should work It should load
kikeminchas
kikeminchasβ€’2mo ago
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
antheas
antheasβ€’2mo ago
It should But below it there should be an extra 260 message
kikeminchas
kikeminchasβ€’2mo ago
the module is not there I'm afraid, checked again dsmeg output and a 'lsmod | grep bmi' only returns entries related to the 160...

antheasβ€’2mo ago
Something went wrong then @Kyle Gospo

Like I said, we probably need those modules Bmi160 conflicts and loads incorrectly without the patch
antheas
antheasβ€’2mo ago
It doesn't conflict That's how it is supposed to work It returns enodev after the chip id check fail And lets the 260 load And lets the 260 load
1/4 Life
1/4 Lifeβ€’2mo ago
Do we know for certain that patch is in fsync 160? To exit I mean
antheas
antheasβ€’2mo ago
160 does not need a patch 150 never needed a patch
1/4 Life
1/4 Lifeβ€’2mo ago
I did before, that's why I was building a kmod
antheas
antheasβ€’2mo ago
It was misinformation
1/4 Life
1/4 Lifeβ€’2mo ago
Interesting
antheas
antheasβ€’2mo ago
We found that out when the patch was going to go upstream And I forced them to check it again

@kikeminchas Can you modinfo bmi260 And see if we get a return?
kikeminchas
kikeminchasβ€’2mo ago
'modinfo: ERROR: Module 260 not found.'
1/4 Life
1/4 Lifeβ€’2mo ago
Huh? That should say module bmi260 not found
kikeminchas
kikeminchasβ€’2mo ago
modinfo: ERROR: Module bmi260 not found.

All right, that's helpful Give me a bit I'll figure it out
