Sorry, I switched up some terminals and accidentially sent the
xorg resolution file from my other computer, the actual file would
be:
# cat /etc/X11/xorg.conf.d/10-monitor.conf
Section "Monitor"
Identifier "VGA-0"
Modeline "1280x960" 122.24 1280 1328 1424 1696 960 961 964 1002
+hsync +vsync
Modeline "1152x864" 112.44 1152 1216 1344 1560 864 865 868 906
+hsync +vsync
Modeline "1024x768" 99.19 1024 1072 1168 1376 768 769 772 810

Modeline "640x480" 62.27 640 656 720 864 480 481 484 522 +hsync
+vsync
EndSection
Sorry for mixing that up, and sorry for the previous message being
HTML-formatted, I forgot to check text only

Hello again,
I both tried setting the display resolution via Modelines and EDID,
like described in the thread [1].
Using the config file
$ cat /etc/X11/xorg.conf.d/resolutions.conf

Xorg starts up without a problem and seems to work quite well.
However when I tried using an EDID file (I tried using edid-generator
[2]),
the screen remained blank despite the EDID file being generated from the
Modelines and loaded at startup, as shown in the dmesg log:
[ 44.001642] [drm] Got external EDID base block and 0 extensions
from "edid/powermac6.4-1152x864.bin" for connector "VGA-1"
[ 44.025758] platform VGA-1: firmware: direct-loading firmware
edid/powermac6.4-1152x864.bin
Though I'm kind of confused as to why it is loaded for VGA-1,
because the eMac only has a VGA-0, DVI-0 and S-video connector
(according to xrandr). The internal monitor is at VGA-0
I added the kernel parameter like so in grub.cfg:
GRUB_CMDLINE_LINUX_DEFAULT="splash
drm.edid_firmware=edid/powermac6.4-1152x864.bin"
I'll have a look at the loading of the edid file in the next few days
again.
regards,
Maite

Hello,
I've just installed the debian 12 port on my eMac.
After the radeon_drm driver does the modesetting, the screen turns
black with the drm showing some errors (I ran dmesg over ssh)
The eMac is special when ir comes to video modes as it requires a
special EDID binary.
