[chimerax-users] ChimeraX issue

[Anthony James Schaefer]

Tom,

Apparently I am using OpenGL 4.5. I ran the glxinfo | grep "OpenGL version"​ command and just saw 3.1. Running glxinfo | grep OpenGL​ shows "OpenGL core profile version string: 4.5 (Core Profile) Mesa 21.0.3", among other things.

Thanks,

Tony

Hi Tony,

There is a ChimeraX command "graphics driver" that reports in the Log panel what graphics driver you are using.  Definitely the graphics will not work if it does not support OpenGL 3.3 so you must have that.

By the way OpenGL 3.3 came out in 2010.  So almost any new driver will have OpenGL 4.5 or 4.6 support and those all provide 3.3 support which is what ChimeraX requires.

Hello,

My Ubuntu 20.04 in Oracle VM VirtualBox can run ChimeraX 1.2.5 and the latest daily build without any issues (aside from the VM lag). It looks like it only has OpenGL ES version 3.2, OpenGL version 3.1, and my host computer (Windows) has OpenGL version 4.6. I don't get any warning when launching ChimeraX in my VM. My Oracle VirtualBox version is 6.1.26 r145957. I've only used it couple of times, and I don't recall changing any settings. I don't know why it works for me and not you, but let me know if I can share additional info or settings.

Like Greg said, ChimeraX's performance on my VM is not great. I only used this VM to figure out why menus on my bundle's tools weren't appearing for some users. The Ubuntu desktop environment I installed (Unity) is one of the desktop environments with a magical setting that made my menus disappear. I don't think I'd recommend using a VM outside of debugging things like this if you can run a native version of ChimeraX.

Dear ChimeraX Team,

I’m trying to use ChimeraX on my VM (Ubuntu 20.04.01), but I’m having the error on the screenshot attached below.

<OpenGL.png>
I tried to update OpenGL to 3.3, and on the terminal it seems that it installed everything but then when I try to open again I’m getting the same issue.

I tried to update OpenGL following this: https://www.reddit.com/r/Ubuntu/comments/8tpq05/how_can_update_my_display_driver_to_opengl_33/

But always when I do the command: glxinfo | grep "OpenGL version" , it shows: “OpenGL version string: 3.1 Mesa 21.0.3”.

Not sure why it is not updating to 3.3 while all the other packages are upgraded.

Could you please advice?

Kind regards
