Just this year I tried to upgrade to 18 (to use ChimeraX, which doesn’t seem to work with 14/16?) but on this version I could not get it to work using the method above.</div><div><br></div><div>I then installed Windows 10, and on this it works well with both Chimera and ChimeraX, but I had to use an older driver for the Quadro card, still downloadable from the Nvidia site, it’s version 392.58. With newer drivers it did not work. I haven’t tried going back to a similar older driver with Ubuntu 18/20, not sure if it’s possible, but maybe that could make it work.</div><div><br></div><div>Let us know how it works for you, and if you manage to get it working with 18/20 especially. If you try 14/16 or Windows 10 and have problems let me know, I can try to dig up more details if needed. I suspect that since drivers have dropped the support it may be harder and harder to keep it going as Tom said. </div><div><br></div><div>Regards,</div><div><br></div><div>Greg</div><div><br></div><div><br><div><br><blockquote type="cite"><div>On Oct 30, 2020, at 12:38 AM, Wei Zhang <<a href="mailto:zhangwei@umn.edu" target="_blank">zhangwei@umn.edu</a>> wrote:</div><br><div><div dir="ltr">Tom,<div><br></div><div>Thank you for these suggestions.
