How to get Xvfb display number

问题

How can I get the display number that used while running Xvfb? For example somebody run

./Xvfb :14

I need somehow to get the used display number 14.

Thanks in advance

回答1:

on a unix system, run

ps -ef|grep Xvfb

and it should list it there with the process

回答2:

There are two ways I can think of:

1. Look for the lock files, which will typically take the form \tmp.X*-lock, where * is the display number;
2. Look at the log files, typically \var\adm\xfvb.log, but might be anywhere. There should be a line which says which display xfvb started listening to.
