Screenshot of the scrambled display on the iMac 21.5" Late 2009
Hello!
I recently did a fresh install of Debian Jessie on a late 2009 Apple iMac 21.5"
which has an ATI Radeon Mobility HD 4670 (model: A1311).
The video display on this machine looks scrambled, particularly, one can see
the framebuffer four times on the display as if looking at an overview of four
virtual desktops with extremely low contrast and no color. The image of each
these views is basically white but visible with the bare eye.
I am attaching a screenshot for reference as well as the appropriate logs
files. More specs on the machine can be found in this Debian installation
report [1].
Cheers,
Adrian
