`░▒▓█ ╔══[ MOTIVATION ]══╗ █▓▒░`

Since asusctl doesn't really care about Ubuntu, I decided to port most functionality from the original G-Helper for Windows.

The application is tested on KDE but other desktop environments should also work.

Pull requests and feature requests are welcome!

`░▒▓█ ╔══[ GPU MODE SWITCHING ]══╗ █▓▒░`

G-Helper manages the ASUS dGPU (discrete GPU) power state and MUX switch through four modes:

║  Eco         dGPU powered off (dgpu_disable=1)                 ║

║  Standard    Hybrid mode (dgpu_disable=0, MUX=iGPU)            ║
║              dGPU available for offloading, iGPU drives display ║
║                                                                 ║
║  Optimized   Auto-switch based on power source                  ║
║              Eco on battery, Standard on AC power               ║
║                                                                 ║
║  Ultimate    dGPU direct (dgpu_disable=0, MUX=dGPU)            ║
║              Best performance — dGPU drives display directly    ║
║                                                                 ║

`╠══[ REBOOT REQUIREMENTS ]══╣`

Transition	Reboot?	Why
Eco ↔ Standard	Usually no	May need reboot if GPU driver is active
Any → Ultimate	Yes	MUX switch is latched, takes effect on reboot
Ultimate → Any	Yes	MUX switch back to iGPU requires reboot

When a reboot is required, G-Helper shows a notification and the pending mode appears in the UI. You can change your mind before rebooting — clicking a different mode cancels the pending change.

`╠══[ DRIVER BLOCKING DIALOG ]══╣`

Switching to Eco while the dGPU driver is active shows a dialog with three options:

Switch Now — attempts to unload the dGPU driver (requires admin password)
After Reboot — saves the mode for next boot (dGPU driver is blocked from loading via modprobe rules)
Cancel — keeps the current mode

`╠══[ KNOWN LIMITATIONS ]══╣`

Ultimate → Eco may require 2 reboots (MUX must change first, then Eco can apply)
MUX switch support varies by model — requires gpu_mux_mode sysfs attribute
Eco mode may require a reboot if the dGPU driver holds a DRM file descriptor
On boot, a systemd oneshot service applies pending GPU mode changes before the display manager starts
