+# 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:
+
+```nix
+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](https://www.nvidia.com/en-us/drivers/unix/legacy-gpu/) which should indicate the
+driver, the exact device isn't listed. However, we can see
+[here](https://linux-hardware.org/?id=pci:10de-1436-103c-1909) 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.
