- The "11" is X, version 11. The "R" is the release number, currently at 5,
- shortly going to 6 with the release of X11R6.
-
- One problem with decyphering the release number of X from a vendor's server is
- that sometimes they modify the server :) For instance, here is a piece of the
- output from xdpyinfo from a VAXstation 3100, running ultrix 3.1, and the DEC
- supplied X server:
-
- name of display: fulton:0.0
- version number: 11.0
- vendor string: DECWINDOWS DigitalEquipmentCorp.
- vendor release number: 11
-
- and here it is from the MIT X11R5 distribution, in this case running on an
- RS/6000, running AIX 3.1.6:
-
- name of display: thunder:1.0
- version number: 11.0
- vendor string: MIT X Consortium
- vendor release number: 5000
-
- and here it is from an RS/6000, running AIX 3.2, with IBM's X server:
-
- name of display: florida:0.0
- version number: 11.0
- vendor string: International Business Machines
- vendor release number: 4
-
- The important fields are "version number:" and "vendor release number:".
-
- So, the IBM-supplied X is X11R4, the MIT X is X11R5, and the DEC X is unknown.
- From what I can tell (and guess :), the DEC X from ultrix 3.1 is mostly X11R3,
- with some nasty bugs.
-
- Does this approach the question?
