On a Wallstreet running kernel 6.1 in Gentoo and using twm: $ fgrep video xorg.0.log[ 70.783] Kernel command line: root=/dev/sda13 video=atyfb:vmode:14,cmode:32,mclk:71 video=ofonly

See Xorg.0.log_no_video_driver_checked.xz, attached. X11 works.If I uncheck "No video driver", video=ofonly is no longer being passed to the kernel, and X11 does not work (text login prompt only):
$ fgrep video Xorg.0.log[ 66.565] Kernel command line: root=/dev/sda13 video=atyfb:vmode:14,cmode:32,mclk:71
$ cat /proc/cmdline root=/dev/sda13 video=atyfb:vmode:14,cmode:32,mclk:71 See Xorg.0.log_no_video_driver_unchecked.xz, attached. X11 doesn't work.I think the atyfb driver is the same as Mach64; I see this in Xorg.0.log when video=ofonly isn't passed to the kernel:
$ grep -i Mach64 Xorg.0.log [ 67.315] (II) LoadModule: "mach64" [ 67.323] (WW) Warning, couldn't open module mach64 [ 67.323] (EE) Failed to load module "mach64" (module does not exist, 0)So we may need to investigate why xorg module mach64 doesn't exist in /usr/lib/xorg/modules/drivers.
