I have recently added the ATI all in wonder 32M PCI graphics card to my dual boot linux Box. The specs of my box are below.
Nvidia Geforce 2mx 400 AGP
ATI All IN Wonder 32Mb Pci
All is well under windows however i do notice that the ati is now the Primary graphics card( in The Bios). It has to be this way for the TV function to Work!!.
Anyway the next step was linux.
Because of the change in bios settings my Nvidia no longer seemed to work!!.
So i tried to get the Ati card working first.
I installed the new version of XFree86 4.2 with little headaches. This supposedly supports both cards!!. I then configured my XFree86 config file ( according to http://linuxdocs.org/HOWTOs/Xinerama-HOWTO-3.html
). I then tested the file and no errors were reported.
Note the device drivers/modules used were "ati" and "nvidia".My Graphics cards are on BUSIDS 1:0:0 and 0:12:0-this was added in the config file.
However after running startx the server tries to start... It kicks the Nvidia card into action and shuts down the ati head and then freezes my linux box -leaving the dreaded hard boot.
I have since tried reconfiguring all my modules to see if this was required....still no joy.
Does anyone have any ideas.
Note I am still quite new to linux so HOWTOs really help.
