Hello all, I have been using chimera and dock6.0 on a RHL9.0 system. More recently if i perform simple processes like coloring a molecule in chimera, the display goes blank and also logs me out of the session. meaning, i come back to the graphical login for my system. I am unable to proceed any further as repeated attempts to do simple tasks simply logs me out. Kindly help with suggestions. With regards, Vinay.

This kind of error is usually due to a buggy graphics driver. Please file a bug using chimera's Help / Report a Bug dialog so the chimera bug database will have a record of the buggy graphic driver version, then update your graphics driver (do not use yum, use the vendor's graphics driver installer), and then follow up the bug with whether or not that fixed it (presumably it will). Good luck, Greg Couch UCSF Computer Graphics Lab

To follow this up: Vinay is using an old version of Mesa, version 4.0.4, a software version of OpenGL, to do his graphics drawing. Upgrading Mesa to version 6.4.1 or later (later is even better) would probably fix the problem. Upgrading Mesa usually is done by upgrading the X11 server. And that said, you'll get even better performance, and OpenGL stability, if you use a NVidia or ATI graphics card. Even a cheap $40 NVidia graphics card and installing the NVidia graphics driver (from NVidia not with yum) will dramatically improve things. I recommend the $100-200 graphics cards because that's the pricepoint where you typically get the most performance for your money. - Greg
