Version: 1:6.7.192-3
Severity: normal
--- Please enter the report below this line. ---
This problem is also apparent in the 1:6.7.192-4 driver, is related to the
xrandr changes, and might be better filed vs. that.
My xorg.conf specifies:

When the xserver starts, I get this in my log:
(II) RADEON(0): DDC Type: 3, Detected Monitor Type: 0

(II) RADEON(0): Output DVI-0 disconnected
(II) RADEON(0): Output VGA-0 using initial mode 1280x768
after xf86InitialConfiguration
and sure enough it sets my resolution to 1280x768, even though it's not a
listed mode in my xorg.conf.
I figured out how to work around this-- I can either use xrandr, or add the
line:
Option "PreferredMode" "1152x864"
To the 'monitor' section of the xorg.conf. The preferred mode solution works,
however that leaves it's own oddness in my logs:
Midway in the xorg.0.log:
(II) RADEON(0): ref_freq: 2700, min_pll: 20000, max_pll: 50000, xclk: 40000,
sclk: 425.000000, mclk: 432.000000
(II) RADEON(0): PLL parameters: rf=2700 rd=7 min=20000 max=50000; xclk=40000

(II) RADEON(0): Port3: DDCType-2, DACType-1, TMDSType-0, ConnectorType-2
(II) RADEON(0): Output VGA-0 using monitor section Generic Monitor
(**) RADEON(0): Option "PreferredMode" "1152x864"
(II) RADEON(0): I2C bus "VGA_DDC" initialized.
(II) RADEON(0): Output S-video has no monitor section
(II) RADEON(0): Output DVI-0 has no monitor section
(II) RADEON(0): I2C bus "DVI_DDC" initialized.
(II) RADEON(0): TMDS PLL from BIOS: 16500 a0112
(II) RADEON(0): Port0:
Monitor -- AUTO
Connector -- VGA
DAC Type -- Primary
TMDS Type -- None
DDC Type -- VGA_DDC
OK, it sees the Preffered Mode and sets it.
Late in the xorg.0.log:
(II) RADEON(0): RandR 1.2 enabled, ignore the following RandR disabled
message.
(WW) RADEON(0): Option "PreferredMode" is not used
(--) RandR disabled
OK- xrandr ignores it, but no longer sets the 1280 x 768 resolution, which is
fine, but makes for a confusing log trail.
So basically, setting PreferredMode fixes my problem, but:
1) If I have modes specified, why not honour those? (As xorg (and xfree86) has
done sine dinosaurs roamed the earth.)
2) The logs I get are confusing on the subject.

Most of these line are often useless nowadays. The driver detects all this
automatically.

Yes, the driver chooses this mode because it detects that it is supported
and probably also because your screen reports it as its "preferred" mode.

That's the expected behavior nowadays. If the monitor reports a preferred
mode, the driver chooses it by default. If you don't like it, you add
a PreferredMode option (or use xrandr to choose after the X startup).

That's expected, RandR 1.2 disables the old RandR extension. I agree that the
message are not very clear though :)
> (WW) RADEON(0): Option "PreferredMode" is not used
Surprising since you said above that the PreferredMode solution works.

Because this is the old syntax for specifying mode, the new one is
PreferredMode.
So there's actually no bug here.

Yeah but that doesn't look too bad to me. If you really want to keep a bug
report
about this, feel free to reopen.
