[Chimera-users] Picking not working in RDS

Mon Mar 30 18:04:13 PDT 2015

Hi Tom,

Thanks again for this great troubleshooting.

I've tested as you described and here are my results:

(1) Ctrl-click to deselect after a "Select All": this works as expected

(2) Ctrl-left-drag does present a box and does select whatever is enclosed
in the selection box

(3) I don't have access to the actual Windows machine -- the RDS machine
is itself a virtual machine.

(4) The results in the "Gathered Information" box reveal the problem: it
is using the GDI renderer! (Full details at the bottom of the email.)

(5) Hover does not reveal any information.

This then begs the question: how to fix the problem? Do we just install a
better OpenGL renderer on the virtual RDS? Are the following articles on
the right track?

Thanks!
