Installation
This laptop comes with Secure Boot enabled, so this must be disabled for the Arch Linux ISO to boot.
Firmware
Hibernation
After resuming from a hibernation, the keyboard and mouse appear not to work. However, all connected USB devices and the touch screen still work.
Secure Boot
This device allows the use of custom keys, but it is untested whether Microsoft Windows keys are required to make the dedicated graphics work. The card works with the Windows keys.
Audio
Speakers
The HP Envy x360 15-ew0xxx has a Realtek speaker set, and a Cirrus Logic amplifier. Both of these need patches to the kernel for them to work. The 3.5mm headphone jack works with no modifications.
To start, clone this repository, which contains the required patches and scripts to install the needed dkms modules
$ git clone https://github.com/Parmjot-Singh/hp-15-ew0xxx-snd-fix.git
After this, change both scripts' permissions to make them executable.
The setup_snd-hda-scodec-cs35l41.sh
script is for the Cirrus Logic amplifier, and the setup_snd-hda-codec-realtek.sh
script is for the Realtek speakers.
Once this is done, you can execute both scripts, which will install needed packages and create DKMS modules to patch the existing kernel modules.
$ ./setup_snd-hda-scodec-cs35l41.sh $ ./setup_snd-hda-codec-realtek.sh
Once these scripts have finished without any errors, you can reboot, and check the journal for the relevant output to see if the modules are working as intended.
For the Cirrus Logic amplifiers:
