The first things to check are the contents of the environment variable LD_LIBRARY_PATH and the output of nm -D to see if the symbol actually exists:

Code: Select all

nm -D /usr/lib64/libXrandr.so.2 | grep -w _XGetRequest

Does gnome-session use the same version of libXrandr as xfce-session/mate-session?

Code: Select all

ldd /usr/libexec/gnome-session-binary | grep libXrandr

I'd also be loking at why you're using non-CentOS versions of things...

libXext.so.6 => /opt/ansys_inc/v201/Electronics/Linux64/defer/libXext.so.6 (0x00007f6a159ea000)
libX11.so.6 => /opt/ansys_inc/v201/Electronics/Linux64/defer/libX11.so.6 (0x00007f6a152e8000)

prepend-path LD_LIBRARY_PATH /opt/ansys_inc/v201/autodyn/lib/linx64/:/opt/ansys_inc/v201/Framework/bin/Linux64:
/opt/ansys_inc/v201/Electronics/Linux64/defer:/usr/lib64:/opt/ansys_inc/v201/polyflow/polyflow20.1.0/lnamd64/libs
this was preventing mate from starting .
moving it to a module file to run after the Desktop get started solved the problem.

[duvayu]

how to mark this as solved?

I think you can edit the title of threads you have started.
