Jeroen,

That was a good suggestion, though it did not work with my Wallstreet. I 
think it's possible that there is an issue with the kernel and with one 
or more Xorg updates, and perhaps that's what is happening with Cedar's 
Wallstreet as well.

Cedar,

On my Wallstreet, I have Debian SID and Gentoo installed. X11 was not 
working with the most current update of Gentoo, with either kernel 
5.18.0 or 6.16.2. Reverting to a Jan 21, 2025 backup, X11 works with 
5.18.0, but not with 6.16.2. So I may be able to do a kernel bisect, 
using the Gentoo installation that has X11 working with 5.18.0 as the 
starting point.

In Debian, I've updated to the latest Debian SID, with no X11 graphics 
working with either 5.18.0 or 6.16.2. I could revert to a backup from 
2024, but I think I'll try to use my working Gentoo installation to 
determine whether there is a kernel regression.

My BootX configuration is as follows (for working X11 in 5.18.0):
  Kernel: vmlinux-5.18.0-pmac (custom kernel, no modules)
  Boot Device: /dev/sda13 (Gentoo partition)
  More kernel arguments: video=atyfb:vmode:14,cmode:32,mclk:71
  No video driver: checked
  Options:
    Force SCSI ON: checked
    Force video settings: checked
    Use specified RAM disk: not checked
