Installing Arch on a Chromebook
Having already tried Manjaro and Endeavouros I have moved my main machine to Arch Linux.
When installing the Chromebook (Asus C300) I had issues with the bootloader and sound, so was reluctant to try installing Arch as it seemed I would have more issues, but I needed a project, so I gave it a go.
My first issue was Ventoy would not boot in UEFI mode even though it is in GPT mode.
So I flashed the Arch ISO directly to the USB drive and it started perfectly.
The actual installation completed without issues, even the bootloader worked without any modifications.
I did however only have a Dummy Output for a sound card, a quick check of the Arch Wiki showed I needed to install two packages, so I did.
pacman -S alsa-ucm-conf sof-firmware
Reboot and the sound works.
I then set up yay and installed the rest of the programs I need and it's all working.
In actual fact the Arch install was easier than Manjaro and Endeavouros so never let it be said Arch Linux is hard.
Update: later a sound problem showed up where the sound would stop and a beep would start for all types of video. This is fixed by adding this
to the default command line in grub.
