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"

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 '15 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 '17 at 17:58

On Ubuntu 16.04, I used:

sudo X -version

  • Something wrong with that? Why did I get a -1? Dec 3 '17 at 20:04

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
