Xorg-server Processes Exist
Is there a Linux BASH command to see if any version of Xorg-server is installed on a RHEL5 or RHEL6 server? I have rpm -q xorg-x11-server-common. I only receive something that states it's not installed or is installed. What I would like to see, is that if a version is installed, the command used will provide version results.
I don't know what process (ps) to look for on a server that does have the files installed because I've never seen it.
Thanks for your help.
