Installation
Secure Boot must be disabled. This is pretty ordinary except for the fact that after disabling it, there will be a BIOS popup, asking to confirm the decision.
Hammering Esc
to get into the boot menu will dismiss the prompt and turn Secure Boot back on.
Accessibility
The appearance of the BIOS is simple but does not have much contrast. It can be navigated with just the keyboard.
Firmware
fwupd does not support this device yet. The firmware can only be updated using Windows. The tool has not been tested with Wine and it is unknown whether it would work.
Under Configuration you will need to disable Action Keys, which is similar to Fn lock, in order for the Fn keys to work under Linux.
Wireless
This device does not have an Ethernet port and the usage of Wi-Fi is pretty much mandatory.
The following kernel module parameters are required and must be applied at boot. Unloading the module and loading it again with the parameters is insufficient.
rtw89_pci disable_aspm_l1=Y disable_aspm_l1ss=Y
Failure to apply them correctly will lead to the card hard freezing and becoming unusable until the next cold boot.[1]
Bluetooth audio may be choppy when wifi is used simultaneously, even if only 5 GHz is used. Disable powersaving mode via a kernel module parameter to solve this[2]:
rtw89_core disable_ps_mode=y
Graphics
amdvlk does not support the AMD Ryzen 5 7530U used in this model. Use vulkan-radeon for any Vulkan compatibility.
