Those who encountered lots of problems with the graphics when running chimera remotely

for example you receive error messages like this one:

X Error of failed request:  GLXBadContextTag
            Major opcode of failed request:  153 (GLX)
            Minor opcode of failed request:  5 (X_GLXMakeCurrent)
            Serial number of failed request:  1352
            Current serial number in output stream:  1352

might be interested in the following solution:

1) install VirtualGL (http://www.virtualgl.org/) on both PCs
2) outcomment the indicated lines in the 'chimera' startup script
3) connect to the server by using 'vglconnect'
4) start chimera on the server with 'vglrun chimera'

that's it!

if [ -z "$nogui" ]
then
   case "`uname -s`" in
       Linux)
           # preload our C++ runtime to avoid
           # ATI graphics driver bug
           # LD_PRELOAD=libotf.so <<<<<<<<<
           # export LD_PRELOAD <<<<<<<<<
           if test -e "$CHIMERA/bin/python2.7"
           then
               python="$CHIMERA/bin/python2.7"
           else

in those cases where chimera works without this trick you might still see a substancial improvement in transmission speed!

Best, Dieter
