How to find out xorg version? or "what's my xorg version?"

Question

ATI docs says i need:

XOrg 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5 or 7.6

Xorg -version says:

X.Org X Server 1.11.1.902(1.11.2 RC 2)
[...]
X Protocol Version 11, Revision 0
[...]
xorg-server 2:1.11.1.902-1

Answer 1

On Ubuntu 16.04, I used:

sudo X -version

Answer 2

You can take a look at the version reported in your packaging system, in Debian:

$ apt-cache show xserver-xorg | grep Version
Version: 1:7.5+8

In this example the version should be 7.5.

Answer 3

It is a bit confusing, because the official documentation refers to the latest versions as X11R7.6 and XServer 1.9. Based on these numbers, you are running "X.Org 7.6" as your X.Org Server is at version 1.11.1.902.

Answer 4

Short answer: 7.6.

X is split up into separate repositories for each component since X11R7.0. The releases is a bunch of module versions known to work together and combined into one set. Individual components changes much more often.

The latest XOrg release, X11R7.6, included xorg-server 1.9.3.

Answer 5

One way is looking at the log file to which the version is printed when the server starts:

head /var/log/Xorg.0.log | grep xorg-server

Answer 6

This link provides a few options: https://support.citrix.com/article/CTX221802/how-to-check-your-current-xorg-version

Ubuntu: dpkg -l |grep xserver-xorg-core

RHEL/CentOS : rpm -qa |grep xorg-x11-server-Xorg

SUSE: rpm -qa |grep xorg-x11-server

The Ubuntu command worked for me. But the answer provided by @user1383029 seems to be the simplest and clearest.
