Hi,

I have found a workaround, which does not require deprecating the system
X11 library.

1. find a copy of the old "working" libX11.so.6 file and copy it
somewhere, eg. /my/private/lib/libX11.so.6

2. bash: export LD_PRELOAD_PATH=/my/private/lib
tcsh: setenv LD_PRELOAD_PATH /my/private/lib

3. run IDL

Now IDL will use /my/private/lib/libX11.so.6 instead of the system library
and it will work correctly.

regards,
lajos
