Re: Powermac g5 strange colors with gui

The card and monitor both worked fine under mac os x, and the color is fine in the terminal. I'm not sure what would indicate a gpu or monitor error, but they a were both working fine under os x.

Thanks for the suggestion though, I'll try a different cable.

Have you ruled out the possibility of a hardware issue either with your monitor, video card port(s), and video cable itself?  Sometimes bent or missing pins on the video cables or loose connections can cause such problems.  Just wanted to throw that out there.

I have installed the kernel as suggested above,  and when I run uname -a it returns that the kernel is running, but the graphical errors persist. Do I need to do something more? I'm a bit of a noob when it comes to graphics, so I may have just gotten it wrong.

Thanks for the help

Hi Aidan,

Welcome to the Debian-on-G5-Macs club!

Peter Saisanas has a patched kernel that fixes this problem.

Check out this discussion in the mail archives:

To cut to the chase,
1) download the two ".deb" files at this URL:
do the following steps as root
2) do a "dpkg -i" on each of these ".deb" files.
3) do "update-initramfs -u"
4) Modify your "/etc/yaboot.conf" file to add a stanza pointing to the
new kernel and initrd files in /boot
5) run "ybin"
6) reboot and select the new yaboot option you created in step 4

You should be good to go

I've CC-ed Peter in case he sees anything I've missed here...
