Having worked as a technician at a college doing computer support, I could tell some war stories. One of the things that really concerned was how resources were used. As a taxpayer, it really concerned me. For example I would have to set up four monitors on one computer. The cost of the monitors and the additional equipment required in the computer for the monitors to work at that time was over a thousand dollars. Now multiply that by at least twenty or more users times several campuses and you are talking quite a bit of money. I want to show you how to have just one monitor, but have the advantage of several screens to eliminate the extra expense, There are times when additional monitors are needed, but that is an exception. Ironically at least one of the monitors usually was just displaying the game of solitaire.
Note: you will want to have a recent machine with a good video card and plenty of memory. . The screen does not artifact like the picture. Just a quirk of the screen shot module.
Step 1: Normal screen
if you look down in the right hand corner of you screen you will usually see the workspace switcher and the trash. On my system I have moved it to the top panel. If you right click on the on an empty space on the panel you can add and remove. If you right click on the workplace switcher it self, you can change the settings like I have from two workspaces to four.
In the first screen is a typical desktop. with the mouse pointing to the switcher. It is empty because we do not have any windows open. In the second screen we have moved to the second workspace (just by clicking on it. ). Firefox was loaded and you can see a small image in the switcher to indicate that. In the third screen, we have moved back to the first workspace where no applications are open. But Firefox is still open. You can tell that because the Firefox image is still shown in the workplace switcher.
So you can tool around the workspaces pretty easily. But I want more.
