## Webcam

Currently not working, and will be responsible for errors in your log related to intel_vsc, int3472-discrete, and intel-ipu6. Some of these errors can be removed by disabling the webcam in the UEFI firmware. See here for a discussion of this issue.

## Firmware

Reason: What about fwupd? (Discuss in Talk:Dell XPS 13 (9340))

Ensure Sound Open Firmware is installed for audio.

## Troubleshooting

### Intel Turbo Boost and eGPU Stuttering

When connected to an external PCIe device (eGPU), Intel Turbo Boost may cause micro-stuttering. The stuttering appears to be related to how the CPU’s power or frequency scaling interacts with the eGPU, which does not occur when using the internal display. To resolve this issue, disable Intel Turbo Boost in the Performance section of the UEFI firmware.
