[ale] Best way to get dual display working (take 2k)

[Scott Castaline]

Here we go again, so now I'm starting to really feel like a ding dong,

I got a HD 5770 PCIe card yesterday from Newegg, supposedly my 
integrated HD 4290 chip is compatible with HD 54xx and above. I had 
already installed the proprietary Catalyst Control Center package so I 
went ahead and installed the card into the primary PCIe x16 slot, 
changed the BIOS settings to initialize the PCIe (PEG) video first and 
had my ViewSonic display plugged into the DVI port. The BIOS portion of 
the boot process got displayed where it should, got to the GRUB menu and 
hit enter to boot default kernel and it just barfed as in kernel panic, 
boot failure.

I then switched it back to the integrated chip and got through the boot, 
logged in and launched CCC as root. CCC not only didn't see the display 
hooked up to the 5770, but didn't see the card either. Doing lspci 
showed 2 different video controllers, (HD 4290, HD 5770), and the GUI 
app Device Manager gave full details on both video controllers, but 
lsmod showed the radeon driver package, shouldn't it be fglrx or 
something like that? Or am I totally out in left field somewhere?

I then went back and disabled the integrated chip throwing it fully on 
to the HD 5770 card, and just got the kernel panic. I switched all back 
to the original and then once logged in I removed the Catalyst package, 
rebooted and the display property app only sees displays on the 
integrated chip.

So what idiotic thing have I done? Or did I just miss some subtle point 
somewhere? Any comments, please?
