File	Description
GHelper-x86_64.AppImage	All-in-one AppImage (easiest to run)
ghelper	Native AOT binary (self-contained, native libs embedded)
90-ghelper.rules	Udev rules for hardware access without sudo
ghelper-gpu-boot.sh	GPU mode boot script (applies Eco/Standard before display manager)
ghelper-gpu-boot.service	Systemd service for GPU boot script

---

Quick test (download + extract):

wget https://nightly.link/utajum/g-helper-linux/actions/runs/25998116262/g-helper-linux-pr-98.zip && unzip g-helper-linux-pr-98.zip -d g-helper-linux-pr-98 && cd g-helper-linux-pr-98

Option A — AppImage (easiest):

chmod +x GHelper-x86_64.AppImage
./GHelper-x86_64.AppImage

Option B — Native binary:

chmod +x ghelper
./ghelper

Install udev rules (required for hardware access):

sudo cp 90-ghelper.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && sudo udevadm trigger

Note: Without udev rules, ghelper needs sudo to access fan curves, performance modes, keyboard backlight, etc.

Install GPU boot service (required for GPU mode switching across reboots):

sudo mkdir -p /usr/local/lib/ghelper
sudo cp ghelper-gpu-boot.sh /usr/local/lib/ghelper/
sudo chmod 755 /usr/local/lib/ghelper/ghelper-gpu-boot.sh
sudo cp ghelper-gpu-boot.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable ghelper-gpu-boot.service
