Public bug reported:
I've tried to run an ATI Radeon 5770 based video card on my x64 10.04
box (up to date as of Sept 14). I've even tried using the 10.8 Catalyst
(was released a few weeks back.. ~late Aug 2010). Thus far the very best
performance I can get is what I'd get using the vesa X11 driver (only I
was explicitly using fglrx).
I gave the x64 10.10 beta a whirl, but didn't even get anything coming
up on my display. I'm aware I could probably feed in some command-line
option on boot and set up on ghetto-graphics. I didn't bother with that.
I've also tried running this card in parallel with a Radeon HD 2600.
When doing that, the ATI Catalyist Center reports the 5770 as an
"Unknown Device"... <sarcasm> Awesome </sarcasm>
I'm concerned in that the 5770 is growing in popularity (for example
it's now common place in a few lines of Apple machines). I've observed
some forums threads with some fairly old discussion on this issue.
Perhaps a 'solution' could entail outright declaring that it's an
unsupported card until further notice. If that's opted for, there should
be a hook or something in grub2 that displays a warning message to
users... As that's a lot more graceful than a completely blank screen.
I can only hope my take on this whole situation is incorrect, but sadly,
I've spent many hours on this. I think the 5770 stands to make 10.10 not
look so great. Hopefully it's an isolated case?
Thanks gang, keep up the awesome work!
