Sorry, I have been meaning to reply about this. I don't believe it's possible to get radeon running without an edid bin (I couldn't get it working anyway, but the situation may have changed since then), and it does need to be loaded from initrd. But I haven't tried a 1152x864 bin file, I use the native resolution of the display (1280x960). I can share my .bin file if it would help.
However, the radeon driver for the 9600, at least on PowerPC, has significant bugs, which I have reported here: https://gitlab.freedesktop.org/drm/amd/-/issues/2269 Best regard, Ed On Mon, 12 Jun 2023 at 20:49, Maite Gamper <vic...@wenzeslaus.de> wrote: > 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 > +hsync +vsync > Modeline "800x600" 77.84 800 816 896 1080 600 601 604 642 > +hsync +vsync > 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 > > regards, > Maite > > On 12.06.23 21:30, Maite Gamper wrote: > > > > 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 > > Section "Monitor" > > Identifier "Monitor0" > > # VendorName "Dell" > > Modeline "1600x1200_120.00i" 167.25 1600 1712 1880 2160 1200 > > 1203 1207 1246 Interlace -HSync +Vsync > > Modeline "1600x1200_170.00i" 248.00 1600 1728 1896 2192 1200 > > 1203 1207 1266 Interlace -HSync +Vsync > > > > # 1920x1440 @ 100.00 Hz Interlaced (CVT) > > # field rate 99.79 Hz; hsync: 76.49 kHz; pclk: 198.25 MHz > > Modeline "1920x1440_100.00i" 198.25 1920 2056 2256 2592 1440 > > 1443 1447 1486 Interlace -HSync +Vsync > > EndSection > > > > Section "Screen" > > Identifier "Screen0" > > Monitor "Monitor0" > > SubSection "Display" > > Modes "1600x1200_120.00i" > > EndSubSection > > EndSection > > > > 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).
