Description

### Kernel

7.0.3-1-cachyos

### Desktop Environment / Window Manager

KDE Plasma

### CPU

Intel(R) Core(TM) i5-1035G1 (8) @ 3.60 GHz

### GPU / Driver

Hybrid Intel/NVIDIA (i5-1035G1 / GeForce MX330)

### Description

After performing a system update and rebooting while the laptop was unplugged and set to powersave mode, the NVIDIA driver modules failed to load. The system returned modprobe: FATAL: Module nvidia not found. This caused 3D applications (like Hollow Knight) to crash with a dxgi page fault because the Vulkan loader could not find the dGPU.

### Steps to Reproduce

Set the system to a powersave profile.

Ensure the laptop is unplugged (running on battery).

Run a system update (pacman -Syu) that includes a kernel or NVIDIA driver update.

Reboot the system.

Check for the module with lsmod | grep nvidia.

### Expected Behavior

The system should correctly trigger the DKMS build process for NVIDIA modules regardless of the power state or battery status. After a reboot, the NVIDIA driver should be active and available for Vulkan/3D applications.

### Actual Behavior

The update finished, but upon reboot, the kernel could not find the NVIDIA modules (modprobe: FATAL: Module nvidia not found). This resulted in the dGPU becoming invisible to the system, causing a dxgi page fault crash in games like Hollow Knight. Additionally, attempting to fix this manually revealed a package conflict between nvidia-open-dkms and nvidia-580xx-dkms.

### Logs / Error Messages

### Additional Context

The issue occurred while the laptop was unplugged and in powersave mode.

The battery was limited to 60% via hardware threshold.
