Hi Marcin,
Try to perform a power reset: https://support.hp.com/ph-en/document/c01684768
That is: turn the computer off, remove all cables, press and hold down
the power button for 15 seconds. Turn the computer on and reconnect
the cables. The brightness buttons should start working.

Hi,
The same happens to me as well. Since I rarely boot to Windows,
I only discovered it now. There does not seem to be any other visible difference
between the working and non-working states, though. There
are no (essential) differences between 'dmesg' or 'sudo fwts acpidump -'
results. So, maybe

I have got a HP HP ZBook Studio G5 laptop.

I got it fixed! In the BIOS I ran quick diagnostic test (includes a
memory check). No problems were indicated, but the next time I booted
the machine (using Ubuntu 21.04 on a USB stick) the memory seemed normal
again. All memory available. And it has worked ever since, independent
on whether I boot
Any news on this? It has been open for over ten years now. AppArmor is
on by default on Ubuntu, and if auditd is used, then the events are
logged using it. Isn't it a security bug if the events don't show up
when queried using ausearch?

This got broken again in 5.4.0-90 (Ubuntu 20.04). USB2 ports work but USB-C
don't. Reattaching USB plug doesn't help, but after suspending and resuming USB
starts working again, until the next time I restart the computer. The reason
seems to be that the temporary fix was reverted:

Public bug reported:
I have an ethernet adapter (ASIX Electronics Corp. AX88179 Gigabit
Ethernet) attached to a USB-C port of my laptop. After update to kernel
5.4.0-90-generic it stopped working again. Same problem with
5.4.0-91-generic. Detaching and reattaching the adapter doesn't help,
but aft
In the kernel 5.4.0-96 it worked randomly. I noticed that instead of the
suspend/resume cycle, it was enough to run 'sudo lsusb -v'. After this
the USB net stick was detected. Note that both 'sudo' and '-v' were
required to have an effect.
Version 5.4.0-97 (still in proposed state) has a proper fi
I downloaded the following packages:
linux-image-unsigned-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb
linux-modules-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb
And installed them with sudo dpkg -i linux-image-
unsigned-5.16.0-051600rc5-generic_5.16.0-05160
That did not help either. I also tried rc6, but the results was the
same. No output even when quiet and splash kernel parameters were
removed.

I tried rc7, but it doesn't boot either.
Just to make sure I'm not doing anything wrong, I installed the mainline kernel
5.15.11. It booted fine, even without nomodeset. And my USB net adapter seems
to be working. At least in the two reboots that I tried. The 5.15.11 version
seems to include yo
The 5.16-rc7 did boot when I gave the acpi=off parameter. The nomodeset
parameter was not required. The network stick worked. But due to acpi
being off, only one cpu was detected.

Possibly related to #1953223 and #1939638. For me the adapter is not
recognized at all.
