OPEN_GL and NVIDIA about semantic_suma

[Chen-Xieyuanli]

Hey @jhjun724, I never tried our method without an Nvidia graphic card (facepalm).
Since our method is based on OpenGL shaders, I guess it would be very hard to make it work without a graphic card.

@jbehley Jens, do you have any comments on this?

Thank you for your answer!

When you install Nvidia driver, don't add '-no-opengl-files'. When you reboot, you will find you can't open you ubuntu. This is true.

Here, don't select 'Ubuntu' but 'Ubuntu on Wayland'
cd /etc/X11
Backup 'xorg.conf'.
Then, set 'xorg.conf' like this:

Reboot and you can select 'Ubuntu' and can go in!
Next, you need
sudo apt install nvidia-settings
sudo apt install nvidia-prime
When you input 'nvidia-settings' you can find this:



Congratulations!
