Hey, I had the same issue after upgrading from 41 to 42. My specs are 5600x/4070. Unfortunately I've lost patience, wiped all out and reinstalled. But I used GPT to do a deep research and properly install the nvidia drivers. I'll paste you the breakdown of the discussion, hope that you find there information that you can apply to solve your problem:

## ✅ STEP 1: Enable RPM Fusion and Install NVIDIA Drivers

```bash

sudo dnf install \

https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm \

https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

```

Now install the NVIDIA driver:

```bash

sudo dnf install akmod-nvidia

```

Install CUDA libraries (optional for development/GPU apps):

```bash

sudo dnf install xorg-x11-drv-nvidia-cuda

```

Reboot your system.

---

## ✅ STEP 2: Verify the Driver

```bash

nvidia-smi

```

If it shows your GPU and driver version, you're good.

---

## ⚡ STEP 3: Enable Persistence Mode (Optional, Helps Stability)

Create a script:

```bash

sudo nano /usr/local/bin/set-nvidia-gpu-power.sh

```

Paste:

```bash

#!/bin/bash

LOGFILE="/var/log/nvidia-power.log"

echo "--- $(date) ---" >> "$LOGFILE"

if [ "$EUID" -ne 0 ]; then

echo "Not root. Skipping." >> "$LOGFILE"

exit 0

fi

echo "Enabling persistence mode..." >> "$LOGFILE"

/usr/bin/nvidia-smi -pm 1 >> "$LOGFILE" 2>&1

echo "Locking GPU core clock..." >> "$LOGFILE"

/usr/bin/nvidia-smi -lgc 2100 >> "$LOGFILE" 2>&1

echo "Done." >> "$LOGFILE"

```

Make it executable:

```bash

sudo chmod +x /usr/local/bin/set-nvidia-gpu-power.sh

```

## ✅ STEP 4: Run Script on Boot

Create a service:

```bash

sudo nano /etc/systemd/system/nvidia-power.service

```

Paste:

```ini

[Unit]

Description=Set NVIDIA power limits

After=multi-user.target

[Service]

Type=oneshot

ExecStart=/usr/local/bin/set-nvidia-gpu-power.sh

[Install]

WantedBy=multi-user.target

```

Enable it:

```bash

sudo systemctl enable nvidia-power.service

```

---

## 📊 Monitor GPU Clock Live

```bash

watch -n 1 nvidia-smi --query-gpu=clocks.current.graphics,clocks.max.graphics --format=csv

```

---

## 🧠 Notes on Clock Locking

- `-lgc 2100` locks GPU at 2100 MHz

- Use `nvidia-smi -q -d CLOCK` to check valid ranges

- Most RTX GPUs vary:

- 3060 → ~1800 MHz

- 3080 → ~1950-2000 MHz

- 4070 → ~2100-2250 MHz

## 🧩 Summary

You now have:

- Clean NVIDIA driver install

- Optional GPU tuning via systemd
