bash sudo nano /etc/modprobe.d/snapdragon.conf

Add the following configuration to the file:

bash options snapdragon-optimizations enable=1

Save and exit the file. Restart your system to apply the changes.

Step 5: Verify Mesa Turnip Driver Installation

To verify that Mesa Turnip drivers are installed correctly, run the following command:

bash glxinfo | grep OpenGL

This should display the OpenGL version and vendor information.

Step 6: Verify Snapdragon Optimizations Installation

To verify that Snapdragon optimizations are installed correctly, run the following command:

bash cat /proc/cpuinfo | grep Snapdragon

This should display information about the Snapdragon processor.

Step 7: Test Performance

To test performance, run the following command:

bash glxgears -info

This will display performance information about the graphics card.

Step 8: Monitor System Performance

To monitor system performance, run the following command:

bash top -u root

This will display system performance metrics, including CPU usage, memory usage, and disk usage.

Troubleshooting Tips

If you encounter any issues during the setup process, try the following troubleshooting tips:

• Check the system logs for errors using the following command: sudo journalctl -u systemd-logind
• Verify that the graphics card is recognized by the system using the following command: lspci -v | grep VGA
