Firmware

fwupd only supports the Thunderbolt device. System BIOS is not supported.

Graphics

The AMD Vega M is completely functional and is usable OOB by the use of the DRI_PRIME environment variable.

See PRIME to get more information.

Fingerprint Reader

As of writing, the fingerprint reader is not currently supported. There is a collaborative effort on a reverse-engineered open-source driver here. Also see this room if you are interested in helping.

Troubleshooting

Overheating

When using the GPU and/or CPU extensively, you may see overheating messages from dmesg:

[ 4233.376972] mce: CPU3: Package temperature above threshold, cpu clock throttled (total events = 20006)
[ 4233.376974] mce: CPU6: Package temperature above threshold, cpu clock throttled (total events = 20006)
[ 4233.376975] mce: CPU2: Package temperature above threshold, cpu clock throttled (total events = 20006)
[ 4233.376976] mce: CPU7: Package temperature above threshold, cpu clock throttled (total events = 20006)
[ 4233.376977] mce: CPU5: Package temperature above threshold, cpu clock throttled (total events = 20006)
[ 4233.376979] mce: CPU4: Package temperature above threshold, cpu clock throttled (total events = 20006)
[ 4233.376980] mce: CPU0: Package temperature above threshold, cpu clock throttled (total events = 20006)
[ 4233.376981] mce: CPU1: Package temperature above threshold, cpu clock throttled (total events = 20006)

It is important to mitigate overheating as it can damage your system and eventually lead to system failure. There are two solutions:

Disabling Turbo Boost

Disabling Intel Turbo Boost resolves this problem. This can be done in the BIOS, or temporarily by echoing 1 to /sys/devices/system/cpu/intel_pstate/no_turbo.

Using smbios-thermal-ctl

Alternatively, you can control thermal parameters using the SMBIOS interface. To do this, you must have libsmbios installed. You can then set the thermal mode to cool-bottom by running smbios-thermal-ctl --set-thermal-mode THERMAL_MODE as root. If this does not lower temperatures enough, try quiet. You can also run smbios-thermal-ctl -i as root to see all supported thermal modes. To see the current status, run smbios-thermal-ctl -g as root.
