Sysinfo

Is there some way that Sysinfo could please show the xserver / driver name
+ its version that the system is running?

Current under "System", it says "Xorg version" is "unknown (24 October 2008
08:00:16AM)". That tells me when the server was built, but does not
indicate which xserver is running, or which verion. (The distro I'm
currently running is Ubuntu 8.10)

P.s. I don't know if I'm using the correct terminology to express what I am
looking for, but I come across tech instructions on the web that say things
like "if you are running fglrx <= 8.24.8 on Xorg <= 7.0.0 then do A,
otherwise do B". I have no idea exactly what I am running, and sysinfo is
currently not of assistance in this regard (it's great in other ways
though, would be great if it helped with this too).
