 Posted: Mon Sep 22, 2008 3:44 pm Post subject: Dual Head and Two GDM Sessions? |
 |
|
I have a host setup as a dual head machine using one display card (NVIDIA GeForce 8400 GS).
GDM starts on one display and the other is blank.
After logging in both displays are one large desktop (as expected).
I would like to have a GDM session on each display, and logging into each GDM leading to a unique session. The same keaybaord and mouse must be shared between both sessions (just to be clear - not a full multi seat setup).
How do you configure this?
TIA |

as for starting 2 gdm sessions not really sure exactly, suppose it would depend on how u start x, something like
DISPLAY=:0.1 (command to start gdm here)
DISPLAY=:0.0 (command to start gdm here) in ~/.xinitrc or something should do the trick if u type startx, or alter the default one that runs when startx is called from the rc system, sorry its not a complete answer but maybe it'll give u some ideas, good luck  |
