Titolo: nuovo monitor ma....

ho installato un nuovo monitor con risoluzione 1280x1024...
ho cambiato la risoluzione in xorg.conf .....
ma quando cerco di cambiare la risoluzione tramite gnome (sul desktop -
Preferenze - Risoluzione dello schermo) è presente come risoluzione
massima la vecchia impostazione (1024x768)...
ciao,
Alfredo

 massima la vecchia impostazione (1024x768)... 
il metodo più sicuro e veloce è modificare xorg.conf;
penso che il tool che hai usato consenta solo risoluzioni presenti nel 
file in questione;

 file in questione;
..già modificato...ma non và....
ho messo la risoluzione 1280x1024 ma non riesco a selezionarla quando
apro la finestra Desktop->Preferenze->Risoluzione dello schermo nella
barra dei menu di gnome.

ma che scheda hai? 
se hai una nvidia, dovresti avere nv oppure nvidia.
Per le ati invece, fglrx o glx (non sono molto aggiornato)
Questo sis non lo riconosco.

I campi HorizSync e VertRefresh che utilizzi potrebbero (nota il condizionale... non ho verificato...) non essere compatibili con la risoluzione 1280x1024. Prova a commentare o a eliminare del tutto le due righe.
Prova anche a guardare cosa dice nel file /var/log/Xorg.0.log
 

> Stai utilizzando il driver Vesa, che non è certo il massimo, anche se credo che a 1280x1024 ci arrivi pure >lui... Ti conviene comunque utilizzare un driver più adatto alla tua scheda.
ho cambiato il driver, ho messo il sis che è adatto per la mia
scheda...ma non va ugualmente...non riesco a selezionare 1280x1024...

boh mai sentita.
Prova con gconf-editor (/desktop/gnome/screen/default/0)
Gli altri DE (kde, window-maker,etc..) ti danno lo stesso problema?

..penso che in realt è la scheda stessa che non consente la
risoluzione 1280 x 1024....

 (II) SIS(0): Not using default mode "1280x1024" (unknown reason)
Non è che il messaggio "unknown reason" sia molto autoesplicativo... però precedentemente viene detto che tale messaggio si riferisce in pratica al fatto che o la scheda o il driver non sono in grado di arrivare a tale risoluzione.
La scheda ci arriva, mentre il driver...
http://www.winischhofer.eu/linuxsispart1.shtml
...sembrerebbe arrivarci lo stesso...
L'unica soluzione mi sembra che sia guardare o chiedere sul forum ufficiale relativo al driver:
http://www.winischhofer.eu/sisforum/viewforum.php?f=3
Dando una rapida occhiata ho trovato questo, che potrebbe esserti di aiuto:

i valori di refresh sono giusti?
per esserne sicuro fai X -probeonly e vatti a vedere i file di log
(/var/log/Xorg.0.log) dovrebbe rilevare i valori esatti ammessi dal
monitor e anche la risoluzione che la scheda può raggiungere..

>i valori di refresh sono giusti?
Non dovresti neppure metterli, perche' hai un monitor ddc.
Te lo volevo dire ieri, ma il fatto che non capisco e'
che di monitor ne vede due: crt1 e crt2... bohh!
Ecco il ddc tuo:

Ti direi: installa una Slackware minimissima e dai xorgsetup,
e' perfetto e non sbaglia un colpo, pero' mi sembra anche
assurdo installare una distro solo per questo.
D'altra parte con una live non credo che vada, ma se ce
l'hai puoi sempre provare.

 (WW) SIS(0): config file vrefresh range 43-60Hz not within DDC vrefresh
non so cosa siano i monitor ddc però se è come dici tu non serve mettere
slack.. basta togliere le righe hsync e vsync da xorg.conf
comunque il problema pare proprio nelle frequenze sbagliate tant'è che ti
da anche un warning.. 
tutti state postando commenti al log di X ma io non lo ritrovo in nessun
post.. il mio newsserver si perde qualche messaggio??

accidenti. Mi sembra strano però (che razza di scheda è?), ho visto che su
google ci sono un paio di link interessanti.

...risolto :-)....
bastava scaricare un applicazione dal sito 
http://www.winischhofer.eu/
chiamata sisctrl che gestisce il chipset sis650.....e ti dice le
modifiche da fare al file xorg.conf.....
una volta modificato il file va tutto a posto...
il bello è che con linux (anche se ci ho messo un po) sono riuscito ad
arrivare alla risoluzione 1280x1024 mentre con windows (ho la
bipartizione...ancora per poco :-) non ci sono riuscito e si ferma a
1024x764.....
grazie a tutti per le utili risposte...
ciao,
Alfredo
