Re: Linux Kernel 6.6.1 broke Logitech g915 TKL Keyboard

Just tried the fixed kernel and will not reverse the breakage of my G502X. Should I open a new thread for it? I think it was speculated that the same thing broke mice and keyboards

I noticed in `lsusb -tvv` I am getting the same ID (046d:c547) as discussed in the ticket https://bugzilla.kernel.org/show_bug.cgi?id=218094

Which fixed kernel did you try  linux-6.6.1.arch1-1.4-x86_64.pkg.tar.zst from post #71 or linux-6.6.1.arch1-1.1-x86_64.pkg.tar.zst from post #6 or did both of them fail to reverse the breakage?

I only tried the one in #71. Will try #6 as well and post back

EDIT:

linux-6.6.1.arch1-1.1-x86_64.pkg.tar.zst from post #6 did actually fix my issue! Thank you so much!

P.S. Do you build these kernels yourself?

You might want to report on https://bugzilla.kernel.org/show_bug.cgi?id=218094 that reverting 9d1bd9346241cd6963b58da7ffb7ed303285f684 restored the functionality of your  G502X.  Might also if you were feeling generous reply to [1] with the same information and it is the same issue as https://bugzilla.kernel.org/show_bug.cgi?id=218094

P.S. Do you build these kernels yourself?

Yes.

Re: Linux Kernel 6.6.1 broke Logitech g915 TKL Keyboard

Hi everyone; I am new to arch and I have the same problem as the first guy (G915 keyboard presses random keys after upgrading to 6.6.1 kernel). I downgraded the kernel waiting to have this bug fixed.

Today the new version of the kernel has been released (6.6.2) and after installing it the keyboard problem persists; now my question is: will this problem be fixed in the future with the next kernel upgrade or must I fix it manually?

I am new so i don't know how the "rolling release philosophy" works.
Thanks to everyone.

Re: Linux Kernel 6.6.1 broke Logitech g915 TKL Keyboard

@skarm it is unlikely that a fix will come from upstream in time for 6.6.3,  the lack of response from the commits author is starting to be followed up [1] but it will still take time for a consensus to be reached on what the correct fix will is,  implement the fix then have the fix back-ported to stable.  The Arch kernel maintainers could apply a fix locally however the current fix (reverting 9d1bd9346241cd6963b58da7ffb7ed303285f684) would remove support for the logitech G Pro X Wireless Superlight that commit added.

There are over 4500 views on this thread...  the interest alone
would suggest your proposition would have a Big following.

And the nature of the bug suggests someone needs to be very
careful about accepting patches for new H/W ... especially, where
we see a good deal more items getting taken off line than there is
new H/W likely to have been sold into the Linux market space...

Upstream intends to revert 9d1bd9346241cd6963b58da7ffb7ed303285f684 as its author is unresponsive [1][2].  The author of 9d1bd9346241cd6963b58da7ffb7ed303285f684 agrees with the revert [3].
I have posted the same information on the Arch bug report [4].

Oh ok, so (please correct me if I'm wrong): they added the code that has been posted in https://git.kernel.org/pub/scm/linux/ke … 303285f684 into a modified 6.6.1 kernel, and this modified kernel should solve the problem.
This will work until the release of the new official kernel which will erase the modified code.
Am I right?

I'm really sorry for all these stupid questions

Almost 9d1bd9346241cd6963b58da7ffb7ed303285f684 introduced the issue.  The kernel I built linux-6.6.1.arch1-1.1-x86_64.pkg.tar.zst reverted 9d1bd9346241cd6963b58da7ffb7ed303285f684 erasing the changes  9d1bd9346241cd6963b58da7ffb7ed303285f684 had introduced to the kernel.

This will work until the release of the new official kernel which will erase the modified code.

Yes.  I do now know which new official kernel will include the revert of 9d1bd9346241cd6963b58da7ffb7ed303285f684.

6.6.3 is now up to its 4th release candidate [1]  so the expected release will be no sooner than Tue, 28 Nov 2023 15:43:06 +0000.

6.6.3.arch1-1 containing Revert "HID: logitech-dj: Add support for a new lightspeed receiver iteration" is now in core testing.

I  got interested in making kernel packages from your bisection excercise.
So I compiled a kernel... no problems.

But when I did "git revert 9d1bd9346241cd6963b58da7ffb7ed303285f684"
I got a not found type of error. 

Are You using the Arch git repo or the Kernel.org git repo?

Relating to G510s fix;  pull request for 6.7-rc4  "LEDs fixes for v6.7" [1] containing "leds: class: Don't expose color sysfs entry" has been opened.
Edit:
The pull has been accepted to mainline [3] unfortunately too late for 6.6.4-rc1 [4].

Queued for 6.6.5 [5].

Missed 6.6.5.

Can confirm fix in 6.6.6  works with no anomalies that I've seen so far.

Thank You.
