Dell Precision 7520

This configuration opts to use the non-free nvidia driver, as UI glitching was often observed with nouveau when using a compositor.

Doesn't work

  • External monitor for luks passphrase entry

Firmware Upgrades

Note that this device is supported by fwupd. To perform firmware upgrades just activate the service:

services.fwupd.enable = true;

Then use fwupdmgr to perform updates

Nvidia Driver

The choice of the legacy_390 driver is based on looking for PCI Device ID 10de:1436. On the nvidia driver site which should indicate the driver, the exact device isn't listed. However, we can see here has nvidia driver "375.82 and newer" listed. Since the newest nvidia drivers don't support legacy devices, the closest version newer than 375.82 was chosen.
