This seems to be a bug in the xserver-xorg-video-radeon driver becasue with xserver-xorg-video-radeonhd I get the full resolution (though other bugs like a wrong frequency of only 60 MHz instead of the needed 108 MHz. I'll open another bug for that issue. |

Hmm, you're right that it's interesting that the resolution is being detected differently by each of the three drivers, and the inconsistency may indeed point to some sort of issue with -ati; I'll upstream it to them for that reason.
However, from your description it seems that none of the drivers get it quite perfect. I note that both -ati and -fglrx are seeing the physical screen size as 0x0 mm, which suggests bad EDID; yet -radeonhd is getting valid looking measurements. But you say that radeonhd is getting the wrong refresh rate, which suggests that even it isn't quite perfect.
My guess is that your monitor provides EDID that is just slightly out of wack from what the xserver expects, and it's mis-parsing it. Perhaps each of the drivers has some correction code that handles the error condition in a slightly different way, thus causing the range of different results. |

Notice how the h/v rates don't match the vendor's advertised capabilities:
Via EDID:
HorizSync 31-65
VertRefresh 58-62
Via DDC:
monitorrange: 31-65, 58-62
Xorg.0.log (radeonhd):
(II) RADEONHD(0): Ranges: V min: 58 V max: 62 Hz, H min: 31 H max: 65 kHz, PixClock max 110 MHz
Advertised specifications:
* Frequency Fh:29-82kHz, Fv:55-86Hz
So, what happens if you plug in these values into your xorg.conf?

Sorry, I didn't have time to investigate further (except that adding the lines you wrote didn't help). fglrx worked fine so I didn't have to work on this issue.
Until today I upgraded to jaunty where fglrx is obiously broken. Bad news: After I removed every trace of fglrx from my system, both radeon and radeonhd are broken as well. radeonhd displayed a distorted screen, radeon nothing at all.
I'll attach the Xorg.logs, both with and without the config lines you posted. |
