I get a segmentation fault when I run cgminer. Probably an issue with that miner though, and not linuxcoin.
Can you post what was happening at the time and the actual error ?
You will have to excuse me but I don't quite get you ? Does aticonfig work with one card and catalyst says there's no drivers or it works with the one card one but doesn't ? I have come across the odd troubles down to a bug with acpi routing. You could try appending the boot line and adding
pci=noacpi
It's solved a load of weird troubles my end

That's odd: if I disable ACPI support in the BIOS I can't even boot, but you're saying to disable it at boot.
This doesn't disable ACPI this just disables the use of ACPI routing information during the PCI configuration stages. I think pci=nobios will work too.
Got full downloads this time. Slightly smaller than previous version. Boots up! New splash no where as nice as previous. Nice not have all the text on boot, but it takes a full 50 seconds to get to desktop.
Did not copy live-rw file yet, only booted to default.
Only managed to fiddle with "secure client" for about 1/2 hour...extremly confusing password issues...will test thoroughly soon, but at this point I think it needs more work to be ready for the average user.
Thanks for testing Smalleyster !! Can you elaborate more on what you found confusing ? I wouldn't test the secure bitcoin client yet. I've found the troubles with the script and have fixed them up. Its hard for a smoker like me to keep track of everything I do

I'm a very scatty person and I'm fiddling with one thing then over to the next without looking at what I done previously

I am full retard when it comes down to organizational skills lol
And you don't like the new boot screen

!! lol Ok I'll make it look a lot more slick on the final version. I was thinking of a spinning bitcoin that fills up with color as the system loads ? I wanted to move from the old splashy to plymouth because it's alot more powerful !!
