Thanks Nikos, that's the part that (apparently) the gentoo wiki |
7 |
doesn't emphasize enough, because my googling has found dozens of |
8 |
us confused gentoo Radeon users making the same mistakes over and |
9 |
over. (And along the way I discovered that you've been saying the |
10 |
same thing over and over :) |

Just two more comments, now that I have the ati-drivers working: |
13 |
|
14 |
First, I forgot to use eselect opengl to select the ati version |
15 |
instead of the xorg version. That helped a lot :p |
16 |
|
17 |
Second, although I realize now that I didn't need kernel drm |
18 |
support in the first place, there is definitely a bug in the |
19 |
drm kernel code somewhere. Even after I finally got the firmware |
20 |
to load properly I still got a "EDID not available" error in dmesg, |
21 |
and hence the black screen during boot. |
22 |
|
23 |
A real problem was that the EDID error was not clearly flagged |
24 |
as an error, so I overlooked it until I stumbled across a post |
25 |
from years ago in this mailing list from someone who didn't miss |
26 |
it. (Thanks to that person, who's name I've forgotten already.) |
27 |
|
28 |
Now that I have the ati-drivers working I, of course, am losing |
29 |
interest in kernel drm support and how to prod someone into |
30 |
fixing it. Shame on me... |
