Auto Selecting/Switching monitors via xorg.conf
 

ModeLine "1152x864" 99.00 1152 1208 1328 1552 864 864 866 902
was the choice of a freeBSD user for his Mag DX17F monitor.

I am using a Nec Multisync lcd 1550m and want to have xorg.conf
detect and switch to a Mag DX17F so other relief volunteers can use
my Nec Multisync lcd 1550m when in the diaster area.

I added a second section for monitor like below. Should I add a
second section for the mode of the Mag DX17F like below?

Section "Monitor"
DisplaySize 300 230
HorizSync 31.5-60
Identifier "Monitor[0]"
ModelName "Nec Multisync lcd 1550m"
Option "DPMS"
VendorName "Nec"
VertRefresh 56.2-75.1
UseModes "Modes[0]"
EndSection

Section "Monitor"
DisplaySize 300 230
HorizSync 30-64
Identifier "Monitor[1]"
ModelName "Mag DX17F"
Option "DPMS"
VendorName "Mag"
VertRefresh 50-100
UseModes "Modes[1]"
EndSection

I also have a second and unrelated question.
After all of xorg.conf has been done correctly, what is the command
to determine which line in modes is currently active in Suse 10?


As always thanks for the high quality help on linuxquestions.
