Dear Centos Users
We are running centos on our HPC.
Indeed, we have a problem with running some software using X11 server such
as pymol. For your information, we are using cygwin to access to the
hpc (using ssh -X -Y
When we are testing glxinfo on my desktop, it gives us the following error:

[username@hpc ~]# glxinfo
name of display: localhost:10.0
X Error of failed request:  BadValue (integer parameter out of range for
  Major opcode of failed request:  149 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  20
  Current serial number in output stream:  23

The weird thing is that when we use another desktop computer running the
same cygwin version and accessing with the same username, glxinfo works
Indeed, echo $DISPLAY on my desktop computer gives us localhost:10.0 ,
while it gives localhost:13.0 on the another desktop.
If I set DISPLAY on my desktop to localhost:13.0, it doesn't work
One more point, if we run glxinfo on the another desktop using my account
and logging at the same time from my desktop with the same username and
setting DISPLAY to 13:0, glxinfo works on my desktop.
Any kind of help will be highly appreciated.
