You only need to install the proprietary Nvidia driver if you have a Nvidia graphics card.  The open source Nvidia driver is not good enough.   See https://www.cgl.ucsf.edu/chimerax/issues.html#linux_graphics.

Hi Tuan,

It appears your graphics driver is only offering legacy OpenGL (non-core) profiles.  Those old graphics profiles were replaced more than 10 years and I have never seen a graphics driver in recent years that only offers legacy profiles.  As the error messages says in your ChimeraX window "Try updating your graphics driver".  That is the only solution.  You do not have to use an Nvidia driver.  You can use a modern Mesa driver (which will be slower when displaying large data).

Hi,

 

I’m trying to install the ChimeraX 1.6.1 on Ubuntu 22 without NVIDIA driver, I can launch the chimerax, but it gives me an error about the graphic driver, and I’m trying to open a pdb file, I don’t see the image at all.  Please see attached below.  Would you please help?

 

Thanks,

Tuan
