## 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.
