    Finally!!
    Standard updates over the last few days have updated the kernel etc so decided to plug my 7800GTX (BIOS Rom hacked as a FX4500) back in and boot to see what happens and success ! :D

    Did you try resetting PRAM or plugging in another GPU?

    Awesome! Your Mac is either a bit mad (like mine) or it doesn't like your 7800GTX

    Macs are mysterious.. My Mac hates OS X 10.5 and 10.4.6+ has serious issues while other versions and Linux work just fine. Simply PowerMacs..

    Hmm - It must be something else that I did then - thing is I have poked about quite a bit on GPU stuff, initially to get the 6600 to support 2d/3d acceleration - You know about the MSI interrupts setting in yaboot.conf :-

    "
    Nouveau driver has issues with MSI interrupts, use yaboot parameter

    • nouveau.config=NvMSI=0
    You can also add it to your /etc/yaboot.conf and update using sudo ybin -v (see the FAQ for more info)"

    https://wiki.ubuntu.com/PowerPCKnownIssues

    Also try using synaptic to update if you're not already - on my PC Ubuntu installation I have had one instance where Ubuntu update has said nothing to update but Synaptic has marked some updates.

    Finally I may be wrong but I heard it may even be down to the revision of the 7800 and even which ROM was used to change the firmware to make it usable in a mac. (I didn't flash mine but purchased already flashed so don't have the ROM) Yours is also a real FX4500 and not a 7800GTX, maybe that's somehow the issue also.

    Other than that I don't think I can help as I don't really know myself why it's started working.
