Question Difference b/w Virtual & Graphical consoles in RHEL5


Hi All,
I am a new Linux user of RHEL5, and i want to know the difference Virtual & Graphical consoles.
I read few docs on the net, and now I am more confused than before.
Could anybody please explain that to me?

Thank you in advance,
Kapil

what differences did you want information on? a virtual terminal is what you call the full screen non-graphical screens you'll see if you hit Ctrl+Alt+F1 to F6 on most linuces from X. and a graphical console is a console window running within X windows.

The virtual consoles are text based command line interface (CLI) whereas the graphical one runs a windows manager (usually either Gnome or KDE) which is a graphical user interface (GUI).

The GUI is a "desktop" in which you can run multiple applications simultaneously. Whereas the CLI is really intended to run things somewhat sequentially. This is a bit of an oversimplification given things like background that can be done in a virtual console.

A key difference would be you can open a terminal session in the GUI and that terminal session would allow you to do CLI tasks while your other GUI applications were still running. You can even open multiple terminal sessions in the GUI desktop. You move easily from one GUI application to another within the desktop simply by clicking on them with the mouse.
The virtual consoles however require you to hit a key sequence to switch between them and the mouse is not used within them.

People who learned computers using MS-Windows or Macintosh will be more comfortable working in the GUI desktop as it is essentially the same concept. However, most of the real power comes in using the CLI because it gives you finer grained control over commands and also allows you to create scripts to automate things. You can even create scripts that you launch from within the GUI desktop.

GUI environments require far more resources and have more complicated interaction with your video card and monitor than CLI which is why when you have issues with your GUI console starting you can go to a "failsafe" session which is actually just CLI.
