I am running MATLAB over a remote linux login. It uses the sortware opengl renderer. ginput() is unusable. very slow and laggy.

Is there anything I can do to improve ginput() response?

Plotting and even using the editor/debugger are quite responsive over the remote connection.

This issue seems to be due to some sort of extreme inefficiency in ginput().

Hi Aaron,

I have few suggestions which might help to you to improve the responsiveness via your remote system:

creating/editing the 'java.opts' file to set the following option: Dsun.java2d.pmoffscreen=false
Switch to VNC for the remote connection
Changing display from 32 bit to 16 bit color depth.

I hope some this suggestions helps to improve the responsive over the remote connection.
