Dual-head on Radeon 9800...

**Vendetta** · 02-15-2004, 05:02 PM

Does anyone know how to configure X to run Dual head on a Radeon 9800 (R350 chip)? Also would like to know if anyone has a list of the modes that are supported by the DesktopSetup option.

heres my current config:

# XFree86 4 configuration created by pyxf86config

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&quot

. 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.

anyone? feeling kinda jipped that my dual head only mirrors itself... the ammount of problems i've been having with linux are making me re-think my decision to leave windows...

**countach44** · 03-03-2004, 02:06 AM

I've never tried dual head

**Vendetta** · 03-03-2004, 02:08 AM

its purty awesome *when it works*
i used to run a game or movie on one screen while working on the second. i miss it

Have you tried using Option "Xinerama", from memory it stetches the screen across the 2 monitors. I also think you need to say the second screen is "RightOf" or something along those lines...
I've done this before so I'll see if I can find out how I did it.

Damn, just read through your config file and see you already have screen 1 rightof screen0. I have no idea now sorry.
The only thing I really can suggest is using Option "xinerama" "on"
That will stretch it across 2 desktops, but it isn't really what you want
Cheers
