Public bug reported:

Binary package hint: xserver-xorg-video-r128

Fresh install on an Apple iMac DV (400MHz slot-loader). Before
installing, I have replaced the PRAM battery, reset the NVRAM and made
sure that the hardware clock was set correctly and kept correctly across
power downs.

I then proceeded to install 9.04 from the alternate CD for PPC. The
install went fine and after the first boot, gdm came up with the login
screen. On closer inspection, however, X was started in PseudoColor 8bit
mode - which is very annoying and almost unusable in some cases. Hence,
I tried to manually configure X to display 24bit TrueColor or at least
16bit (after having installed all updates). I came across the following
issues:

1) The "out-of-the-box" xorg.conf file is empty. I have no experience with 9.04 yet, so I don't know whether it's supposed to be that way.
2) After adding the information from one of the many xorg.conf files that can be found for Ubuntu on PPC (which includes the r128 driver), X failed with "no device found" (see attached Xorg.0.log-r128-no_device). This despite all evidence pointing to this iMac having an ATI Rage 128 (see lspci.txt)
3) I then removed the "Driver" instruction to let X choose the driver itself. This resulted in another failure to run X, this time with an error about "modified mode" (see Xorg.0.log-no_driver-modified_mode). In fact, I got this error for all colour depth settings except for 8bit - which is just what I want to get rid of.

I will now proceed and install 8.04 from alternate to see whether the
machine will then show different behaviour. The original MacOS 9
installation on that box *did* run in TrueColor mode, so I assume that
the hardware is fine.
