In putty I can configure exact values for environment variables on remote host, for example

On Linux I have ~/.ssh/config file which contains entry like this

Host calculon
 User dims

Is it possible and how to configure remote host environment variables on Linux in the same way i.e. without specifying them on command line or separate commands?

I can specify

SendEnv DISPLAY

in config, but this will require to set this variable on local host via separate command. This is both excessive and for DISPLAY variable is also a nonsense.

Also I have read about ~/.ssh/environment file and wrote this

dims@pterosaur:~$ cd .ssh
dims@pterosaur:~/.ssh$ cat environment 
DISPLAY=pterosaur:0

but this has no effect (variable DISPLAY is not set on remote host).

Note that sshd is already configured to accept DISPLAY variable and accepts it normally from Putty. So the task is to configure Linux client in the same way.

Configuration is documented in man 5 ssh_config.

SendEnv can be used if the server supports and is configured to accept it:

SendEnv

Specifies what variables from the local environ(7) should be sent to the server. Note that environment passing is only supported for protocol 2. The server must also support it, and the server must be configured to accept these environment variables. Refer to AcceptEnv in sshd_config(5) for how to configure the server. Variables are specified by name, which may contain wildcard characters. Multiple environment variables may be separated by whitespace or spread across multiple SendEnv directives. The default is not to send any environment variables.

If that is not possible you can also configure remote host shell with your environmental variables (using .profile etc., for bash see documentation on bash startup files).
