I have an ubuntu 12.04 system with an amd radeon hd 4670 graphics card running beautifully. I am interested in upgrading to 12.10 but unsure about catalyst (fglrx) support for the card. the latest driver doesn't support the card. Can i use the legacy (12.6) driver for ubuntu 12.10. Is the support available through jockey? Does the legacy driver support the X-org server in 12.10? is there a ppa or way to downgrade the X-server? Thanks in advance
I don't use a 4xxx series card but there is a new PPA available for the purpose you describe.
