the problem with switching back to the console after having started X exists at my laptop, too (NV GeForce2Go)
If you find an solution, tell me please!
TwinView should be useable with these addons to your
config file (xorg.conf/XF86Config-4) in the appropriate device section
(see also the readme file shipped with the nv drivers)
Code:
Option "TwinView" "1"
# enter the refresh rates of your external monitor if on a laptop, the lcd is first device
Option "SecondMonitorHorizSync" "31-85"
Option "SecondMonitorVertRefresh" "55-102"
# Orientation can be RightOf, LeftOf, Above, Below, Clone
Option "TwinViewOrientation" "Clone"
# In this case, i can switch between internal, external and both monitors.
Option "MetaModes" "1024x768,1024x768; 1024x768,NULL; NULL,1024x768"
# Monitors can be of type DFP, CRT or TV
# omit this line to autodetect on X startup
#Option "ConnectedMonitor" "crt,dfp"
Option "TVStandard" "PAL-B"
Option "TVOutFormat" "SVIDEO"
