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 isn't currently supported. There is a collaborative effort on a reverse-engineered open-source driver here. Also see this room if you're 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 sudo smbios-thermal-ctl --set-thermal-mode THERMAL_MODE. If this doesn't lower temperatures enough, try quiet. You can also run sudo smbios-thermal-ctl -i to see all supported thermal modes. To see the current status, run sudo smbios-thermal-ctl -g.
