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 class=""><br class=""></div><div class="">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 class=""><br class=""></div><div class="">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 class=""><br class=""></div><div class="">Regards,</div><div class=""><br class=""></div><div class="">Greg</div><div class=""><br class=""></div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Oct 30, 2020, at 12:38 AM, Wei Zhang <<a href="mailto:zhangwei@umn.edu" class="">zhangwei@umn.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Tom,<div class=""><br class=""></div><div class="">Thank you for these suggestions.
