I originally posted this on the Debian user forums but I was directed to
this mailing list. Hopefully I can give you enough information for some
guidance on troubleshooting this.
I have an iMac G4 "desk lamp," 512k of RAM, 200 GB HD, I believe the
processor is a 7450. I downloaded the Debian Jessie netboot powerpc
"mini.iso" image from here and burned it to a CD:
http://http.us.debian.org/debian/dists/jessie/main/installer-powerpc/current/images/powerpc/netboot/
Installation seemed to go smoothly, no errors, and I selected MATE as the
desktop choice during install. The only other option I selected was the
"additional desktop software" (sorry, do not remember the exact text).
However, after installation, when it boots, one of the last messages you
see is:
[FAILED] Failed to start Load Kernel Modules.
Last line is something along the lines of:
fb: switching to nouveaufb from OFfb NVDA,NVMac
And then the text starts dissolving, and the entire screen cycles through
different colors. I presume it is sitting at the graphical login prompt but
it's not displaying correctly.
Based on some Google searches, it seems like I should be able to resolve
this by editing /etc/modules using nano from a command prompt but I can't
get to that point. After the machine starts cycling through the colors, I
press ctrl-alt-F1 through ctrl-alt-F12. If there is a command prompt being
offered, I can't see it.
I also tried different yaboot options I found in searches that were
supposed to avoid using the video driver. Unfortunately these didn't work
either, but maybe I'm not choosing the right ones.
How do I get the machine to boot straight to a regular text login instead
of the X-based one?
Also, this machine worked fine running Mac OS X this morning (partition was
deleted during the install process), so I don't think it's the hardware.
Please let me know what I can do. Thank you in advance for any help you can
provide.
