Public bug reported:
Hello. For unknown reasons, the brightness up and brightness down keys
on my ProBook 455 G5 are being mapped to F20, which is the microphone
mute key. Because of this, the screen brightness cannot be adjusted by
pressing the brightness keys. However, the screen brightness can still
be adjusted by software such as panel applets.
I did a fair amount of testing to arrive at this conclusion. acpi_listen
reports the brightness keys as F20, same with my microphone mute key.
showkey reveals that the scan codes are identical for both the
brightness keys and the microphone mute key. On the off-chance it was
some kind of userspace issue, I also performed these tests from other
distributions, both systemd and non-systemd variants. The same issue is
present there as well.
The only conclusion I am left with is that the kernel is not reporting the keys
correctly. I haven't been able to find any other reports of a similar
situation, so I am unsure how to proceed from here. Please advise me on how I
can help you find a solution to my issue. Thank you.
