Acer Cloudbook
At least four different versions of this laptop exist: AO1-131-C9PM and AO1-131-C620 with a 11" screen, and AO1-431-C2YR and AO1-431-C7F9 with a 14" screen. All of them also have slightly different hardware (e.g. wireless card).

Wireless NIC: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter 802.11b/g/n (rev 01)
AO1-431-C7F9 (possibly)
Wireless NIC: Intel Corporation Dual Band Wireless AC 3160 (rev 83)
BIOS configuration
- Touchpad: Basic
- Boot Mode: Legacy
- Boot priority order: the eMMC block device needs to have a lower boot priority than the USB bootable device.
Then save and exit.
Kernel parameters
Without these options, the installation image will not load at all:
- edd=off
- noapic
Therefore these parameters needs to be added at the end of the kernel parameters' line of the boot launcher:
linux /vmlinuz-linux ... edd=off noapic
Installation
- Everything should function without any issues thanks to the previous kernel parameters, proceed to install the image as normal.
- The module for the wireless NIC is included with the kernel, so Wi-Fi works out of the box.
- Do not forget to add edd=off noapic to the kernel parameters of the boot launcher's configuration file.
Installation (UEFI mode)
- No additional kernel parameters are needed.
- The UEFI firmware may be hardcoded to boot from Microsoft's EFI boot loader at
/EFI/Microsoft/Boot/bootmgfw.efi(tested on AO1-431-C2YR, BIOS 1.06)
BIOS configuration
- Touchpad: Basic
- Boot Mode: UEFI
- Boot priority order: the eMMC block device needs to have a lower boot priority than the USB bootable device.
- Secure Boot: Disabled, or use BIOS menu to trust the Arch ISO bootloader.
Then save and exit.
Troubleshooting
GDM
If Gnome/GDM is installed and started, the login page will flicker up-to the point that it becomes nonfunctional. See GDM#Use Xorg backend.
High load average on idle
The kernel module rtsx_usb_ms is loaded at boot time yet is non-functional (the kernel thread associated to the module when inspecting with top is a zombified process) and unnecessary for the system to function. The module can safely be blacklisted.
Bluetooth
At least in AO1-431-C8G8 bluetooth device is deactivated via RF-kill by default. After activating it works flawlessly with bluez.
