I don't know if you have a lot of experience with IRIX and other flavors of UNIX, or if you are new to UNIX, so please let me know if what I am about to say is on target or not.
The main desktop interface in IRIX is called the "IRIX Interactive Desktop," and it looks like this -
http://m1.ikiwq.com/img/xl/82787GlqZPpXZk0ZxCiF7b.pngSGI also supported the CDE, or "Common Desktop Environment," for a little while. While CDE is the most common interface used with many commercial UNIX platforms, it is relatively rarely used with IRIX. The CDE desktop looks like this -
http://en.wikipedia.org/wiki/File:DECwi ... v7.3-1.pngThe document that you linked is for the CDE. Which environment are you using? That might impact the diagnosis of your problem and the advice that you get.
Unless you have a compelling reason to run CDE, I think that almost everyone would agree that you are much better off running the Irix Interactive Desktop.
In the Irix Interactive Desktop, you should be able to right-click (no need to hold the ALT key) anywhere on the blank desktop and get a menu of "Desktop" options. If you try that, do you get the menu? (I think something similar happens with CDE, too, but it's been a long time since I used it.)

I am at home now (the O² is at work), but I can tell you that the mouse is a 3-button model, without scroll wheel. In effects, I thought that the mouse could not be read correctly by the system, but the left button does what a left button is expected to do... I tried
everything with all three buttons, with and without ALT and CTRL, but to no avail.
What should I do tomorrow morning about the rodent?...

Is the mouse from SGI, or is it a third party mouse? In most cases, a mouse without a wheel needs the kernel parameter pcmouse_mode to be set to zero. To find out which mode your system is using, type this command:
Code:
systune pcmouse_mode
The output should say which mode you are using. If it is not "0", you can change it as an administrator by typing (as root -- be very, very careful) the following command and then rebooting:
Code:
systune pcmouse_mode 0
If that fails, you might try shutting down, connecting a different PS/2 style mouse, and then rebooting the machine. You may need to change the pcmouse_mode if you change mice. Again, instructions for that are at
