=== Lid reopen hybernate issue ===


Upon closing the lid to the laptop and reopening, an issue occurs where the device will intermittently go back into hybernate mode after around 10-30 seconds. Setting the kernel parameter <code>button.lid_init_state=open</code> fixes this issue. The following is an example configuration (working in NixOS 22.05):

In order to get both the laptop display and external displays working, in the BIOS settings set Chipset > GPU MODE to "Dedicated GPU only".

After setting the GPU MODE to "Dedicated GPU only" in the BIOS, enabling [[Nvidia#sync_mode sync mode| Nvidia]] is necessary in order for both the laptop's display and external display/ports to work properly. Here is an example configuration snippet for NixOS 22.05:

The text <code>7-3</code> is composed of the bus number (7) and the port (device?) number (3).
</syntaxhighlight>7-3 is the Bus: 7 and the Port: 3


How to figure those out you can read here:
To find the bus and port numbers, read this post: [https://superuser.com/questions/1707773/how-to-turn-usb-connected-device-on-and-off-in-linux]
