This question already has an answer here:
I have an ATI Radeon X1600 256 MB DDR3 (I think that is rv550 and it uses Gallium R300 driver). However, Unity is slow and that has always been the case since its introduction. I'm wandering is there a way (hack, fix, workaround) to use the old fglrx driver which supports this video card in any of the latest three releases of Ubuntu.
Yes, I know that my video card is not new but in Windows 8 I can use my old driver and to make it work it was no problem though it has been made for Windows Vista (which is some 7 years ago).
