Re: Various problems with HP Spectre x360 aw2xxxng (Tiger Lake)

Hi people,
For the fingerprint sensor: I reverse-engineered it and wrote a working PoC (it works on my machine, at least). If some of you can test it and report back, that would be awesome.
I requested comment from the libfprint developers on how to proceed with the implementation and I'm currently waiting for a response from ELAN: https://gitlab.freedesktop.org/libfprin … issues/406

Screen does not rotate in GNOME

If I remember correctly, GNOME 40 only enables on-screen keyboard and rotation if the device is in tablet mode (screen is folded past 180°). Make sure you have iio-sensor-proxy installed. It works well for me.

Don't hold your breath on this but I was planning to try and debug it at some point. It doesn't seem to occur with Windows' bootloader, it always seems to occur with open-source EFI binaries for some reason. It happens with at least GRUB, rEFInd and the mok manager application. My suspect is that their implementation uses some API that the MS bootloader does not, so my idea was to enable logging and somehow trace it. Maybe it's a GNU EFI bug? I haven't tried with boot loaders built with EDK2.

Yes, but the top speakers (located under the keyboard) are still quiet.

Re: Various problems with HP Spectre x360 aw2xxxng (Tiger Lake)

Hi everyone,

I just want to come back with some information about the boot problem. Since I only use Arch Linux and don't need multi boot, I decided to give EFISTUB a try. With EFISTUB I don't have the issues while booting with external devices attached.

If I remember correctly, GNOME 40 only enables on-screen keyboard and rotation if the device is in tablet mode (screen is folded past 180°). Make sure you have iio-sensor-proxy installed. It works well for me.

I can't confirm that. I tried to fold the laptop but still no screen rotation. It worked sometimes back (after updating to GNOME 40), but not at the moment. Even on a fresh Arch Linux installation screen roatation is not working.

Have you installed `iio-sensor-proxy`? Once you install that it should work out of the box after restarting the gnome shell.

You can check with d-feet or whatever d-bus explorer you like whether you have `net.hadess.SensorProxy` exposed in the system bus. You should also be able to find the raw accelerometer data in `/sys/bus/iio/devices/iio:device*/in_accel_{x,y,z}_raw`.

Yes, I had iio-sensor-proxy installed. I gave iio-sensor-proxy-git a try today and it worked with that. Maybe this his something to do with the latest BIOS update I installed.

Re: Various problems with HP Spectre x360 aw2xxxng (Tiger Lake)

Dear all,

this post has been extremely useful for Archlinux installation on my new HP 14-dv0000

Some notes:
- in my case, update to F.11 or F.20 bios does not fix keyboard delay
- missing sound has been fixed installing firmware. I'm not sure which package did the trick, as I installed all of them: alsa-firmware sof-firmware alsa-ucm-conf
- I encountered some trouble with my wifi card, as it disappeared at some point. I suspect it had something to do with Windows (it happens after I booted in windows). A couple of reboot fixed that.

Maybe we can update the wiki to include my HP model?

Appending "i8042.nopnp=1 i8042.dumbkbd=1" to kernel boot parameters fixed the keyboard initialization delay. I lost my caps lock led but it was a minor sacrifice.

I tried "Appending "i8042.nopnp=1 i8042.dumbkbd=1" to kernel boot parameters," but my keyboard still takes approximately 20 to 30 seconds to start working upon booting or waking. Also, my `caps lock` key light still works.

Specifically, I modified the following line in `/etc/default/grub`

      GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet i8042.nopnp=1 i8042.dumbkbd=1"


That and the fingerprint reader doesn't work, but I have not attempted to fix that.

Re: Various problems with HP Spectre x360 aw2xxxng (Tiger Lake)

Correction, adding "i8042.nopnp=1 i8042.dumbkbd=1" did work, I just had to run `grub-mkconfig -o /boot/grub/grub.cfg` .

Now my keyboard has no initialization delay on boot or wake up.

Thanks

The USB booting issue is fixed with the new BIOS update! Version F25 on the HP Spectre 14. I can now boot with my mouse receiver plugged in, no hang. This thread has been super helpful.
