bingel:
I have two requests:
- The first is for
Bridgman (il tipo del supporto linux di AMD cui mi riferivo nel precedente post): I read that the ATI Catalyst restricted drivers stop too soon to support the older cards (I don't know if this is true, however, according to complaints read on various forums, cards purchased only a few years ago are no longer supported). Will be this support extended in the near future or old cards will continue to be left at the mercy of the open drivers?
- The second is for anyone who knows what's what and who is able to compile a list of all the problems encountered with the ATI Catalyst restricted drivers.
For example I see that Kano (sviluppatore debian) points the finger at Xv but I have read almost all the threads and I noticed that there are many other problems.
Someone could then take stock of the situation?
I'm not an expert further my English is not good otherwise I would do it.
Thanks in advance.

Risposta alla prima domanda:
On the Catalyst drivers, R3xx-R5xx cards are only supported on existing supported platforms. They will not supported on newer kernels and xservers. Only R6xx-Evergreen cards will be supported on newer kernels and xservers. This is mainly because the Catalyst drivers share a lot of resources across platforms (Linux and Windows) and that generation of hardware has gone into maintenance mode.

However, the open source driver will continue to support R3xx-R5xx cards on newer kernels and xservers. So if you want to use the Catalyst drivers for that generation of hardware you will have to stick with a supported Linux distro.

Risposta alla prima domanda:
I don't quite understand the "at the mercy"-part. If there's bugs in fglrx, you're "at the mercy" of AMD to fix them. If there are bugs in the OS drivers and AMD doesn't fix them, anyone else can.
I am aware that the OS drivers still lack some features compared to fglrx, but if you're concerned about company-dependence, wouldn't OS drivers be a better choice?
Risposta alla seconda domanda:
The most popular are these:
- xv has slightly washed out colours.
- ATIs video decoding API is inferior to nvidia's VDPAU
- fglrx isn't too stable with wine games (but for most recent games, you'll need a real windows anyway).
- fglrx uses an older method for 2D acceleration that doesn't work too well in some situations
And for some people it's not stable or doesn't install at all,
but the same is true for nvidia's drivers (come possiamo vedere, anche NVIDIA sembra abbia problemi nonostante rilasci driver certificati).

Risposta (o integrazione) al secondo intervento di agd5f
The problem with that is those "supported" distro's are only supported with security and patch updates for so long.

integrazione dell'elenco dei problemi:
- multi-monitoring/randr/external displays are still a bloody mess, especially with notebooks
- aticonfig is extraordinarily good at messing up xorg.conf, for example when you need exotic configs for hybrid graphics
- standby/hibernate with fglrx is prone to blackscreening your system to death

hu? What's wrong with fglrx's xrands implementation? For me, it works way better than nvidia's proprietary TwinView crap.

It was 7 years for R300, 5 years for R4xx, 3 years for R5xx...
We normally aim for about 5 years, but it depends on when support gets dropped on other OSes since so much of the code is shared.
...For clarity, we dropped support for 3xx, 4xx and 5xx at the same time, that was not "a declining trend"
