Certain Quanta ACER HD User Facing webcams do not work on linux due to driver issues. This is known (judging from the comments in the kernel drivers), but hasn’t been fixed.
However, there is a fix from Giuliano69 on GitHub. I created a patch with diff using this fix on linux-6.10.7 and then built linux-cachyos from kernel manager, adding the fix to patches to verify that it works (it does). I uploaded the generated patch file on GitHub as well (as proof of concept, rather than to be actually used, as I’ve no idea what I’m doing).
Since CachyOS already adds some kernel patches with fixes, I was wondering if this patch (or, more precisely, such a patch) could be added as well (and become the first distro that I know of that officially fixes the issue, lol).
