I'm new to using containers/Linux but have recently had to pick it up for my job. To analyse the data I get, I use a Docker container my job provided me. All of the commands in the container work perfectly EXCEPT gv/gs. Whenever I try to display a .ps file, it tells me "unable to display". When I try to find a solution to this problem online, there's a lot being said about an X11 server and ssh'ing, but I can't seem to see how that might apply to my problem. I'm not ssh'ing, it's a Linux container.

Just for clarity's sake-- the problem isn't that gv/gs etc. aren't installed. I have installed the software to view postscript files, but when I use the commands it gives me the error message 'unable to display'.

If anyone has any idea what it could be, I'd really appreciate it! Thanks!
