Public bug reported: [Problem] Machine boots to blank screen. Xorg.0.log shows "no devices detected" and "no screens found"
[Steps to reproduce] Boot Raring daily live ISO or install from alternate and reboot. [Workarounds] None Found Failed attempts: remove "quiet splash" from yaboot kernel appends kernel boot parameters tried separately = video=offb:off, video=ofonly, nomodeset create minimal xorg.conf per nouveau wiki and repeat kernel boot parameters create minimal xorg.conf using FBDEV and repeat kernel boot parameters [System Environment] lspci-nnvv attached GNU/Linux 3.8.0-7-powerpc64-smp ppc64 PowerPC G5 1.6Ghz Nvidia FX5200 Ultra diplay connected via DVI port to VGA adapter processor : 0 cpu : PPC970, altivec supported clock : 1600.000000MHz revision : 2.2 (pvr 0039 0202) timebase : 33333333 platform : PowerMac model : PowerMac7,2 machine : PowerMac7,2 motherboard : PowerMac7,2 MacRISC4 Power Macintosh detected as : 336 (PowerMac G5) pmac flags : 00000000 L2 cache : 512K unified pmac-generation : NewWorld [SEPARATE Issue] noted for clarity - may complicate problem on this hardware This hardware has known "phantom / ghost" port issue on TV-1. Prior to 12.10, all that was needed to boot with nouveau KMS was video=TV-1:d. I mention as others with the same hardware, but connected via the "Apple Display Connector" port may report ability to fall back to FBDEV booting with nomodeset. That has never been the case for my hardware due to the "phantom port." Link is clarification of this SEPARATE issue. https://bugs.freedesktop.org/show_bug.cgi?id=39866 Forthcoming logs all booted with kernel appends video=TV-1:d drm.debug=0x4 plymouth:debug . "quiet splash" have been removed from yaboot kernel appends.
