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

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.

  • ok, not as simple! just found out the hard way that ATI's catalyst drivers are NOT compatible with X11, even if it's technically "7.6"

On Ubuntu 16.04, I used:

sudo X -version

  • Something wrong with that? Why did I get a -1? Dec 3, 2017 at 20:04
  • No idea who downvoted you, but this seems the simplest answer. Thanks!

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.

  • I'd rather use dpkg -p xserver-xorg which shows what actually installed instead of the querying the remote. Jul 25, 2015 at 10:49
  • This gives me version of an old xserver, although i running a new one. I posted in a new answer how I got it on a up to date Ubuntu system Dec 1, 2017 at 17:58
  • In my ubuntu 22.04 the above shows: 1:7.7+23ubuntu2 while sudo X -version and head /var/log/Xorg.0.log | grep xorg-server show 2:21.1.3-2ubuntu2.5.

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.

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

  • This has the benefit of also showing you display driver details etc, which is also handy in debugging issues.

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.
