External Email - Use Caution        

It reads like you are trying to install on an Ubuntu system, e.g., Ubuntu 18 or Ubuntu 20? On Ubuntu you can try the install command,
$ sudo apt install libjpeg62

Also it would be good to know what freesurfer release you are installing, e.g., 7.1.1.

Something may not be right with your environment for remote X programs.  I would check you have the DISPLAY environment variable setup in your xshell or xmanager setup.  On my terminal DISPLAY is set to,

$ echo $DISPLAY
:0

I don’t know how xshell and xmanager setup your X environment, but I would first try running a simple X windows program like xeyes and get that to work (displays a pair of eyes that track the cursor) before running tksurfer, etc.

Hello, Fs
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
