== Problems == | |||
=== Dual Monitors === | |||
If you encounter problems having multiple monitors connected to your gpu, adding `video` parameters for each connector to the kernel command line sometimes helps. | |||
For example: | |||
<syntaxhighlight lang="nix"> | |||
boot.kernelParams = [ | |||
"video=DP-1:2560x1440@144" | |||
"video=DP-2:2560x1440@144" | |||
]; | |||
</syntaxhighlight> | |||
Of course you have to adjust the connector names (like `DP-1`), the resolution and frame rate accordingly. | |||
To figure out your connector names, use: | |||
<syntaxhighlight lang="bash"> | |||
head /sys/class/drm/*/status | |||
</syntaxhighlight> | |||
with your monitors connected. | |||
