Question Two screens on separate graphic-cards. Possible on linux?


I'd like to use 2 different screens on 2 different graphic-cards (one screen on each). One screen sholud eighter work as an extension of the desktop or have full screen applcations on it. What I try to do is to be able to have a movie runing on one screen while the other can be used for work at the same time.

The cards I use are: GF2MX400 (AGP) and 3dfx blaster banshee (PCI).

The program must work on eighter kanotix (debian-based) or mandrake 9.2.

Certainly possible. Investigate the Xinerama extention to XFree86/Xorg.

Google has a ton of info on the topic.

yeah... you are looking for Xinerama.... an example of it's use with xorg would be..
the contents of my xorg.conf file
Code:
# Xorg configuration created by system-config-display

Section "ServerLayout"
	Identifier     "Multihead layout"
	Screen      0  "Screen0" LeftOf "Screen1"
	Screen      1  "Screen1" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
	Option	    "Xinerama" "on"
	Option	    "Clone" "off"
EndSection

Section "Files"
# RgbPath is the location of the RGB database.  Note, this is the name of the 
# file minus the extension (like ".txt" or ".db").  There is normally
# no need to change the default.

# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

	RgbPath      "/usr/X11R6/lib/X11/rgb"
	FontPath     "unix/:7100"
EndSection

Section "Module"
	Load  "dbe"
	Load  "extmod"
	Load  "fbdevhw"
	Load  "glx"
	Load  "record"
	Load  "freetype"
	Load  "type1"
	Load  "dri"
EndSection

Section "InputDevice"
# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
#	Option	"Xleds"		"1 2 3"

# To disable the XKEYBOARD extension, uncomment XkbDisable.
#	Option	"XkbDisable"

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults).  For example, for a non-U.S.
# keyboard, you will probably want to use:
#	Option	"XkbModel"	"pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#	Option	"XkbModel"	"microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#	Option	"XkbLayout"	"de"
# or:
#	Option	"XkbLayout"	"de"
#	Option	"XkbVariant"	"nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
#	Option	"XkbOptions"	"ctrl:swapcaps"
# Or if you just want both to be control, use:
#	Option	"XkbOptions"	"ctrl:nocaps"
#
