Hi Zonglei,
The problem was related to the fact that I was accessing another computer remotely to run FreeSurfer, and I needed something to support the graphics. I assume you are also accessing a remote computer? I was using Exceed, which was working fine for tkmedit and tksurfer, but for some reason, qdec did not like Exceed. So I installed WinaXe Plus, and that has been working fine.
Good luck,
Dana

Hi Dr. Moore: I met the same error reported as you posted when I used qdec in our system. Have you already resolved this probelm ? If you have the solution to resolve it, please give me some clues.
Thanks

I am trying to use qdec for the first time, and I get the following error message:
X Error of failed request: GLXBadRenderRequest Major opcode of failed request: 132 (GLX) Minor opcode of failed request: 1 (X_GLXRender) Serial number of failed request: 1705 Current serial number in output stream: 1709 Locking assertion failure.

I am accessing our linux computer remotely using ssh from a windows machine--I don't know if this is related to the problem.
Thanks, Dana
