<div class=""><br class="">
</div>
<div class=""> Thanks for those tips. We usually tell ChimeraX and Chimera users to give up any hope of OpenGL remote display with X windows as this rarely works unless the graphics drivers on the two machines are identical. This has nothing to do with the
specific apps, no OpenGL apps work. This kind of remote display worked pretty reliably 20 years ago in the days of SGI but seems barely supported now. Glad to hear that it can sometimes work for those who need to use this low performance 3D rendering method.
We recommend moving your data to the visualization machine for the best visualization experience.</div>
