9.04 PPC: r128 does not detect ATI Rage 128 on G3 iMac

[Thomas Ribbrock]

Binary package hint: xserver-xorg-video-r128

Ubuntu 9.04PPC "out-of-the-box" fresh install on an iMac DV 400MHz (G3, slot-loader):

As the default installation results in 8bit only display (256 colours, PseudoColor mode), I have tried to force the usage of the r128 driver using a minimal xorg.conf (see attachments). This fails, as the r128 driver fails to detect the card (see attached Xorg.0.log). I could not see any difference between including the "disable 'dri'" statement and leaving it out - in the log, it looks like this statement is actually ignored/overridden by the X server.

If I run strace against "startx" (strace -fo xserver.trace startx), I can see that the driver accesses the AGP bus and both PCI busses (see also attached output of "lspci -vvnn").

Under 8.04, the same driver works fine on the same hardware.

Partial SOLUTION:

xorg.conf must contain the line

BusID "PCI:0:16:0"

in the "Device" section - this will detect the ATI Rage. I had not tried this as I assumed that the lspci (hex-)value should be correct, but apparently, xorg expects decimal.
Hence, the installer needs to somehow come up with this.

Unfortunately, the r128 driver now crashes. I will open a new bug for *that* problem.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.
