# 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.
|
||||
|
||||
## Device Details
|
||||
|
||||
- Dell Precision 7520 (07B0)
|
||||
- Intel Core i7-7820HQ CPU (Kaby Lake)
|
||||
- 32GB RAM
|
||||
- SK hynix SC311 SATA 1TB
|
||||
- Intel HD Graphics 630 (Coffee Lake)
|
||||
- NVIDIA GM206GLM [Quadro M2200 Mobile]

|
||||
## 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.
