If Ubuntu didn't find any drivers automatically, you can try installing drivers manually. Follow the steps below for NVIDIA GPUs:
- Add the official PPA for NVIDIA drivers:
bash
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
- Install the recommended NVIDIA driver:
bash
sudo apt install nvidia-driver-XXX
For this step, check with the latest driver version shown for your GPU by "ubuntu-drivers devices", the replace the "XXX" with the driver version you find.
- Reboot your system:
bash
sudo reboot
When you reboot your system, there will be a window asking you to input the password you set before rebooting. When the system reboot successfully, check with"nvidia-smi".
4.Check BIOS Settings (For laptops)
If you're using a laptop, it's possible that your system is set to use the integrated graphics (like Intel) by default. You can:
- Reboot your computer and enter the BIOS/UEFI setup.
- Look for settings like "Hybrid Graphics," "Discrete Graphics," or "Switchable Graphics."
- Change the setting to Discrete Graphics to force the use of your dedicated GPU.
- Force Re-detection of Hardware
You can try forcing Ubuntu to re-detect your hardware by running:
bash
sudo update-pciids
This will update your PCI IDs, potentially helping Ubuntu recognize your GPU.
Once you've gone through these steps, check again if the drivers are being detected with:
bash
ubuntu-drivers devices
