Ahoj,

mam 2 graficke karty od ATI (MSI RX1650, Sapphire RX1650 PRO) a snazim se rozjet dual screen, pricemz kazda karta mi bude vytvaret vystup na jedeen monitor. Vysledkem ma byt siroka plocha, na ktere budu pracovat.

Momentalne pouzivam fglrx, pze ten se mi podarilo rozchodit na notebooku (stejny ucel, akorat ze tam je jedna dual-head karta).

Muj xorg.conf:

# GRAFICKE KARTY
Section "Device"
	Identifier	"ATI"
	Driver		"fglrx"
	BusID		"PCI:1:0:0"
	Screen		0
EndSection

	Identifier	"ATI2"
	Driver		"fglrx"
	BusID		"PCI:2:0:0"

	Monitor		"Levy Monitor"

	EndSubSection
EndSection

	Identifier	"ATI2 Screen"
	Device		"ATI2"
	Monitor		"Pravy Monitor"
	DefaultDepth	24
	SubSection "Display"

	EndSubSection
EndSection


Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		0 "ATI Screen"
	Screen		1 "ATI2 Screen" RightOf "ATI Screen"
	InputDevice	"Generic Keyboard"
	InputDevice	"Configured Mouse"
	Option		"Xinerama" "on"
EndSection

Section "DRI"
	Mode	0666
EndSection

Pro jistotu jeste pridavam at je vse jasne:

lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc RV530LE [Radeon X1600]
02:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 71c7 (rev 9e)

Co by mel xorg.conf delat je snad jasne: Z prvni graficke karty (ATI) dat vystup na prvni monitor (ATI Screen) a ze druhe karty (ATI2) na druhy monitor (ATI2 Screen) a plocha by mela byt pres oba. Na notebooku mi takovato konfigurace funguje.

Vysledny problem: Druha karta se mi neaktivuje a vystup jde tedy pouze na prvni monitor.

V logu vidim nasledujici problemy:

FATAL: Error running install command for fglrx
Requesting insufficient memory window!: start: 0xf4000000 end: 0xf5ffffff size 0x10000000
(EE) Cannot find empty range to map base to
(EE) fglrx(1): Cannot read V_BIOS
(EE) fglrx(1): PreInitInt10 failed
(EE) fglrx(1): PreInitConfig failed
SetVBEMode failed
(EE) fglrx(1): PreInit failed
(EE) fglrx(0): atiddxDriScreenInit failed, GPS not been initialized. 
(EE) AIGLX: Screen 0 is not DRI capable

Takze to odhaduji na to, ze fglrx driver neumi pracovat se dvema kartami najednou.

Mate nekdo nejakou zkusenost, nebo vite nekdo jak a co s tim? Diky moc za radu
