Randr e risoluzione schermo

[Akiro]

ciao a tutti,
ho una Mandriva Linux release 2008.1 (Official) ed una scheda video Radeon rv250 con i driver ATI, ad ogni riavvio del pc la risoluzione del monitor è settata a 1400x1050... come posso fare per rendere permanente la classica 1024x768?

nel xorg.conf 1400x1050 non compare nemmeno!? Randr ha un suo file di configurazione?

ecco il mio xorg.conf:

non è proprio possibile utilizzare altre risoluzioni con i driver ATI e randr??

[sacarde]

prova a generare il config dal comando:

xorgcfg -textmode

oppure dal classico:

Xorg -configure


p.s.
se hai kde dovrebbe esserci nelle proprieta' schermo anche la risoluzione
da configura-desktop ---> display

[Akiro]

nada, riconfigurando xorg ritorna comunque a 1400x1050

e su configure desktop--> display, sotto "dimensioni e orientazione" appare scritto:
"your X server is using the RandR extension at version 1.2 or greater qhich doesn't have any configuration yet"

ma io l'ho sempre interpretato come se l'utility grafica non fosse ancora capace di configurare xorg adeguatamente... ma forse sbaglio io ad interpretare il messaggio ed effettivamente i driver non supportano ulteriori configurazioni
se fosse così però sarebbe ridicolo per l'Ati -__-


edit: in effetti controllando meglio randr ha poco a che vedere con Ati...

[andy caps]

guarda semmai man xrandr

ci sono anche degli esempi a cui cambiare le modeline

xrandr --newmode "1400x1050@75" 155.85 1400 1496 1648 1896 1050 1051 1054 1096 -hsync +vsync



oppure



xrandr --newmode "1400x1050@60" 122.61 1400 1488 1640 1880 1050 1051 1054 1087 -hsync +vsync

[sacarde]

e se dentro xorg.conf lasci solo:

...
...
Modes "1024x768"
...
...

[andy caps]

avevo letto al contrario

prova anche con

Forces to use a 1024x768 mode on an output called VGA:
xrandr --newmode "1024x768" 63.50 1024 1072 1176 1328 768 771
775 798 -hsync +vsync
xrandr --addmode VGA 1024x768
xrandr --output VGA --mode 1024x768

oltre naturalmente a lasciar solo "1024x768"

[Akiro]

appena posso riprovo, grazie dei consigli

[Akiro]

vabè, ho fatto un ultimissimo tentativo lasciando solo come modes "1024x768" ma al riavvio il monitor è sempre a 1400x1050.

mi piegherò al volere del mio pc tanto anche questa risoluzione non è poi male... mi da solo fastidio che adesso potrà usarla come scusa quando aprirò troppe finestre/applicazioni per andar più lento! 8D
