Package: linux-image-4.5.0-2-powerpc Version: 4.5.4-1 During Debian installation the background color is inverted on PPC system. At least on my Mac Mini G4, the default background color shows up as red from begining to start (only the last screen turn blue).
Looking at the module loaded during the installation I can see radeonfb, which I suspect is the one responsible for handling of `/dev/fb0`. After installation I tried reproducing this color inversion without any luck so far. It is non-trivial to `rmmod radeon`, so instead I used (and rebooted): $ cat /etc/modprobe.d/radeon.conf blacklist radeon However upon reboot `/dev/fb0` is already setup. But neither radeonfb nor radeon module seems to be loaded (using lsmod) but lspci output is rather confusing [*]. I can also see: $ cat /proc/fb 0 OFfb ATY,RockHo Playing with the virtual screen with a red and blue color and `fim`, all images looks weird, I could not figure out if there was something special to setup so that I can display a red or blue image in `fim`. Lastly, I can run `dmesg` and the color looks right (error messages are displayed in red, timestamp in green). I'd like to keep this bug open until I find what is going on with this color inversion on PPC/ATI. $ lspci -s 0000:00:10.0 -vvx 0000:00:10.0 VGA compatible controller: Advanced Micro Devices, Inc.
