By the way, my xorg.conf file was a custom multi-head configuration that I had been building over the years.
Right now, I am not using multi-head. So, a default configuration makes more sense. The biggest conflict seems to be from trying to use a Matrox G450 (or G550 - whatever it is), which was built for 4:3 ratio with a 16:9 display. The display resolutions are highly limited. So, the default configuration makes me happy for now. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-fbdev in Ubuntu. https://bugs.launchpad.net/bugs/400875 Title: 9.04 PPC: fbdev wrongly configured in X Status in “xserver-xorg-video-fbdev” package in Ubuntu: Expired Bug description: Binary package hint: xserver-xorg-video-fbdev Ubuntu 9.04PPC "out-of-the-box" fresh install on an iMac DV 400MHz (G3, slot-loader): After the install, xorg.conf stays empty. Hence, X tries to figure out the correct settings and driver automatically. On my iMac, X fails to detect the built-in ATI Rage 128 card (see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg- video-r128/+bug/400864 ) and subsequently tries to use the fbdev driver. When doing so, X does start, however, only 256 colours are used (8bit PseudoColor mode). I tried to investigate the cause for this and tried several things: 1) Create a minimal xorg.conf (the attached version contains some commented out lines from experimenting) with "DefaultDepth 24" in the Screen section. This results in an error message "FBIOPUT_VSCREENINFO succeeded but modified mode" (see attached Xorg.0.log). 2) I tried the same thing using "DefaultFbBpp 32" instead of "DefaultDepth 24". The result was the same. 3) I noticed in the log file that apparently the modes are checked against the fbdev set-up. The default frame-buffer set-up as listed by "fbset -i -v" is attached as well. It can be seen from this output and Xorg.0.log that the frame buffer seems to have 8bit only and only some 600KB of video memory. Hence, I tried modifying these settings with fbset - to no avail. I also tried adding a "VideoRam" statement to xorg.conf - also to no avail. I was not able to change any settings. In the end, I am still not able to run anything but 8bit graphics using the fbdev driver. My impression is that this is due to the frame buffer being in the wrong mode itself, but this seemingly cannot be changed easily. The same hardware works fine with 24bit under 8.04, using the r128 driver.
