What happens if you put back in the 58xx card and clear out the

figure out the monitor settings on it's own? Do you get the screwy
pink line then?
The HD 5750 gives me the pink line before X even runs! The problem, I
believe, lies with the HDMI support in the Evergreen DRM code. I am not
the only Evergreen user to be affected by this.
Just for kicks, I removed xorg.conf completely. The Xorg.0.log files
produced were barely different: the changes mostly have to do with
autodetection of Default Screen and loss of Monitor sections.
Interestingly, the removal of the Monitor sections causes this change in
the Xorg.0.log output:
-(**) RADEON(0): Display dimensions: (593, 371) mm
-(**) RADEON(0): DPI set to (82, 82)
+(==) RADEON(0): DPI set to (96, 96)
The first two lines are expected, since I removed the monitor section
that specified the physical size of the monitor. The line replacing
them ought to be indicating a DPI of 82 since the correct resolution and
screen size are detected:
(II) RADEON(0): clock: 154.0 MHz Image Size: 593 x 371 mm
Instead, either the radeon driver or the X server is altering the
physical screen size to this:
(II) RADEON(0): Setting screen physical size to 508 x 317
This also happens with my HD 4850 (even with my old xorg.conf being
used) if I use the DVI-to-HDMI converter cable. With the new HDMI cable
being used (on HD 4850), I get the correct physical size: 593x371.
Baffling....
Good lukc, and thanks for all your testing. I'm slowly getting
tempted to upgrade from my x1650 card. :]
Thanks. I purchased the HD 5750 knowing that Linux open driver support
would be lousy or nonexistent. Or, stated another way, I knew that
support was being newly introduced, and it was my big chance to
contribute by testing the new support as it is developed!
My big regret is that I still have not improved my skill set enough to
contribute code. I taught myself C, and then C++, in the early 1990s; I
was even writing assembly language subroutines and integrating them with
C++ programs. But I stopped programming for many years. I actually
tutor some beginning courses at a local community college, but have only
been learning Unix tools very slowly since installing Linux for the
first time in 2005. I have a long-term goal of becoming a Debian
Maintainer (or Developer).
At this late date, I had hoped to be able to contribute code (instead of
mere testing) to efforts like Evergreen support in DRM, radeon, and
Mesa. It's very frustrating to not have the time or the skill set to be
able to do so (yet). Hopefully within a year or two....
