# Dell Precision 5490
|
||||
|
||||
The internal monitor needs Linux Kernel >= 6.7 so enabling hybrid graphics does not work out of the box in 24.05. Setting
|
||||
Linux kernel versions prior to 6.7 may not function correctly with the internal monitor, as official support was introduced in version 6.7 (https://www.phoronix.com/news/Linux-6.7-Intel-Meteor-Lake-Gfx). You can enable experimental support by adding the following parameter:
|
||||
|
||||
```
|
||||
boot.kernelParams = [ "i915.force_probe=7d55" ];
|
||||
```
|
||||
|
||||
helped but introduced some screen tearing.
|
||||
However, this may lead to some screen tearing.
|
||||
|
||||
Setting
|
||||
If possible, you might benefit from a newer kernel, for example:
|
||||
```
|
||||
boot.kernelPackages = pkgs.linuxPackages_latest;
|
||||
```
|
||||
in nixos-stable worked with no problems.
|
||||
as it seems to work without any issues.
