After installing FreeSurfer, use tkregister2, tkmedit, tkurfer, and recon all -- help to verify whether the installation is successful. 

The first and fourth commands are OK, but the second and third commands display the same error: glut: fatal error in tksurfer.bin : could not open display:  localhost:17.0.

I use xshell as a terminal, and I have installed xmanager. I used to be able to use it, but now I have problems.

And when I use the Freeview command, an error is reported as follows: freeview.bin : error while loading shared libraries:  libjpeg.so .62: cannot open shared object file: No such file or directory

Do you know how to solve the above problems?

Looking forward to your reply
