| If you have problems, start by checking the value of ''DISPLAY'' at the remote system (using "''printenv DISPLAY''" or similar). Some servers don't switch on X11 tunnelling by default, in which case you have to use the "''-X''" flag when connecting to them (eg "''ssh -X hostname''"). | If you have problems, start by checking the value of ''DISPLAY'' at the remote system (using "''printenv DISPLAY''" or similar).
