M’he comprat un ordinador molt cucu.
Jo uso Mandriva Linux i volia provar aixo del blender.
Pero la minipantalla que porta el meu nou portàtil no em deixava… (12″)
El problema va ser que el krandrtray que porta el KDE no anava bé, i el XFdrake ara no deixa posar extensió de pantalla a una segona.
Si enxufava una pantalla de 15″ reconeixia el mode de 1024×768.
hi ha una ordre que es diu xrandr que a seques contesta quins modes de pantalla suporta les pantalles que tens al sistema
en el meu cas:
[festuc@sonica ~]$ xrandr
Screen 0: minimum 320 x 200, current 2560 x 1024, maximum 2560 x 1600
VGA connected 1024x768 (normal left inverted right x axis y axis) 338mm x 270mm
1280x800_75 75.0
1280x800_60 60.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3
640x480 75.0 72.8 66.7 60.0
720x400 70.1
640x350 70.1
LVDS connected 1280x800+1280+0 (normal left inverted right x axis y axis) 261mm x 163mm
1280x800 60.0*+
1024x768 60.0
800x600 60.3
640x480 59.9
TMDS-1 disconnected (normal left inverted right x axis y axis)
TV disconnected (normal left inverted right x axis y axis)

Aquest maximum 2560 x 1600 S’aconsegeix posant al /etc/x11/xorg.conf una linea :
Virtual 2560 1600 a dintre les Subsection "Display"
Dons això si posava la de 15″ i executava
xrandr --output VGA --left-of LVDS --mode 1024x768
Em sortia bé
pero per posar la de 17″ haig d’afegir un nou mode a la llista de la sortida VGA
primer el creo
xrandr --newmode 1280x1024 106.97 1280 1360 1496 1712 1024 1025 1028 1059
Despres l’afegeixo
xrandr --addmode VGA 1280x1024
i finalment ja puc posar la VGA a 1280×1024
xrandr --output VGA --left-of LVDS --mode 1280x1024
et voilà :)
