Titolo: Risoluzione max 640x480

Salve a tutti.
Ho installato l' ultima Ubuntu su un pc con scheda grafica Nvidia FX5500.
All' avvio della live il video funziona correttamente, ma dopo l' 
installazione il sistema e' di fatto inutilizzabile perche' la massima 
risoluzione e' 640x480.
Sto cercando in tutti i modi di farlo funzionare, ho disistallato i 
driver ufficiali (e ho scoperto che i neaoveau erano gia' presenti), ho 
modificato il xorg.conf, niente.
A parte che non capisco come possa essere che da live funzioni e da 
installato no, mi aiutate per favore a risolvere?
Grazie.

 [    14.892] (WW) NVIDIA(GPU-0):     unrecognized EDID Header.
Questo puzza molto
Hai provato a fare uno /etc/X11/xorg.conf?
 
Anche se a 640 dovresti cmq poter aprire nvidia-settings, impostare la 
risoluzione del monitor e eventualmente salvare il xorg.conf che ne risulta.


 risulta.
 
Non sono disponibili opzioni superiori...
Grazie comunque.
 
p.s.:resta incompransibile che la live funzioni....


Prova a creare un nuovo utente e entrare con quello
in ~/.conf potresti avere un monitors.xml o simile con dentro una 
risoluzione nel tuo caso di 640
 
eventualmente fai anche un
grep -r 640 *
e vedi che salta fuori


  La live potrebbe usare il driver VESA.  Il tuo Xorg invece usa il
driver nvidia, che ha problemi a capire in automatico i parametri del
monitor via EDID (Extended Display Identification Data).  Puoi tentare
queste due strade:
 
0) Ti crei, da terminale, senza che Xorg stia girando, un file xorg.conf
con i comandi:
 
   [root@host ~]$ Xorg -configure &&\
   test -f /etc/X11/xorg.conf && mv -vi /etc/X11/xorg.{conf,bak}
   [root@host ~]$ cp -vi xorg.conf.new /etc/X11/xorg.conf
 
1) Ci inserisci staticamente i parametri del tuo monitor, ad esempio:
 
	Section "Monitor"
	        Identifier   "LCD-19"
	        VendorName   "Hanns-G"
	        ModelName    "HQ191DP6"
	        HorizSync    31 - 80
	        VertRefresh  54 - 75
	        Option       "dpms"
	EndSection
 
2) Se ancora non basta, cioè se Xorg non riesce lo stesso a costruirsi
una Modeline adatta per il tuo monitor, provi a dargliene una fatta a
mano.  Ad esempio, nella stessa sezione di prima ci aggiungi una di
queste due linee:
 
	        #Modeline     "1280x1024_75" 135.00 1280 1328 1472 1688 	1024
1025 1028 1066 +hsync +vsync
	        Modeline     "1280x1024_75" 135.00 1280 1320 1464 1688 		1024
1025 1028 1066 +hsync +vsync
 
  Quindi nella sezione "Screen" gli dici di usare questa Modeline, ad
esempio inserendola nella sottosezione "Display" di default (o in tutte
queste sottosezioni), come in questo esempio per il display a 16 bit per
pixel:
 
	SubSection "Display"
	                Viewport   0 0
	                Depth     16
	                Modes   "1280x1024_75" "1280x960" "1152x864" "1152x768"
"1024x768" "800x600"
        EndSubSection
 
  Le righe Modeline e Modes non devono andare a capo nel file xorg.conf.
 
  Un paio di volte me la sono cavata così, un paio d'altre volte ancora
non bastava.  Una di queste volte è stato con una Matrox G550 quando il
monitor era collegato all'uscita DVI, ma ho risolto collegando il
monitor all'uscita VGA (sgratt, sgratt ,sgratt :-?)
 
  Ovviamente tu devi usare i valori di frequenza orizzontale e di
tracciamento verticale idonei per il tuo monitor; le Modeline dovrebbero
andare bene così come sono salvo che il quadro potrebbe non essere ben
centrato (se ricordo bene la seconda lo sposta un pochino a destra
rispetto alla prima).

 Ho installato l' ultima Ubuntu su un pc con scheda grafica 
Nvidia FX5500.
io ho avuto un sacco di problemi con le schede nvidia e ubuntu.
dopo 1 settimana ho dovuto cambiare distro perche' non c'era 
modo di farle andare correttamente


 
Grazie mille.
Avevo iniziato ad andare in questa direzione, ma ho dovuto interrompere
Ora mi trovo a migliaia di km di distanza dal pc in oggetto, potro' 
riprovare tra un mesetto, grazie ancora.
