New monitor on running system
I have two servers running Fedora core and Fedora core 3. These systems are on a KVM along with a windows box. The monitor has died and has been replaced with a LCD screen. However both systems are running with an active X session.
The LCD does not support the screen size/refresh rate and therefore I can not see anything on the monitor. However, both systems are running VNC servers and I can access these from the windows box.
I would like to change the default resolution so that the LCD monitor can be used. I would like to be able to kill the current X session either from the console (without seeing what I am doing) or from a terminal session. How can I do this? Once that X session is ended, how can I tell it I have a different monitor?
PS - these are not critical servers and I can reboot them if ncessary, but I would rather learn a little and see if it can be done without rebooting.
