Titolo: No screens found

Ciao ragazzi,
premetto che sono un neofita di Debian (3.0 r4).
Dopo aver installato il sistema base e aver configurato il sistema grafico
(xf86config), al momento di inizializzare la grafica sul monitor ricevo l'
errore "No screens found".
Penso che sia un errore di settagio dei parametri del monitor, ma non so
quali scegliere.
-Caratteristiche mio monitor: 17" catodico - risoluzione massima 1280x1024
(ma la tengo sempre a 1024x768) - 85 di    refresh
-Caratteristiche scheda video: Nvidia Geforce MX 200, 32MB
La scheda grafica viene riconosciuta, mi manca solo il monitor.
Qualcuno di voi sa i settaggi per le caratteristiche del mio monitor?
Ringrazio anticipatamente per i Vostri aiuti, ciao :-)

 quali scegliere.
AFAIK è un problema di impostazioni in /etc/X11/XF86Config (o
XF86Config-4).
Dovresti avere una sezione "Monitor" con un identifier, che deve essere
lo stesso che dopo ritrovi nella sezione "Screen" come "monitor".
Infine, nella sezione "ServerLayout" dovresti avere come "screen" lo
stesso identifier della sezione "Screen".
Per esempio:
Section "Monitor"
	Identifier "MIOMONITOR"
	...
EndSection
Section "Screen"
	Identifier "MIOSCREEN"
	Monitor "MIOMONITOR"
	...
EndSection
Section "ServerLayout"
	Identifier "Default Layout"
	Screen "MIOSCREEN"
	...
EndSection

 quali scegliere.
Io ho la tua stessa scheda e schermo (lcd) 17" da 1280x1024.
Devi innanzitutto avere installato il supporto ai driver nvidia.
Mi ricordo di aver avuto anch'io problemi con uno di questi 2 programmi:
xf86cfg e xf86config. Non ricordo quale dei 2 ma uno era una sola. Ti
consiglio di rimuovere (o magari "spostare") tutti i file
/etc/X11/XF86Config* :
mv /etc/X11/XF86Config* /dovetipare/
xche' xfree86 potrebbe leggere il file di conf sbagliato (che si chiamano
XF86Config e XF86Config-4).
Io l'ho sempre settato a 800x600, 60Hz, 24bit e non mi ha mai dato noie.
Prova anche col mio script: (nota: in caso di danni a persone, cose,
animali, non mi riterrio' responsabile dell'accaduto)

Io ci ho provato e ho messo gli stessi parametri
con cui ho configurato la Slack, ma ottengo
una serie colorita di errori: vedo il monitor
piccolo e scentrato e con una risoluzione inferiore
a quello che dovrebbe. Ho provato varie soluzioni,
ma il risultato non cambia...
