Re: PowerMac G5, GeForce FX 5200, black screen

[Dan DeVoto <dand1972@yahoo.com>]

The bug report I left for the black screen problem was with Driver/Radeon:

https://bugs.freedesktop.org/show_bug.cgi?id=90220

Since you have an Nvidia card, maybe you'd want to file a separate bug report under Driver/nouveau.  If my bug report is any indication, expect to be swamped with replies ;)

Regards,

Dan

 Wow, Dan!
 
 Unlike Luigi, I have no need
 for X on this machine.  I’m happy (indeed, I’m
 overjoyed!) to have a working text console.
 
 I’m now using
     append=“ nomodeset”
 On my MacPro G5, which has an nvidia card.  To
 be specific:
 
     $ lspci
 | grep -i VGA
     0000:0b:00.0 VGA
 compatible controller: NVIDIA Corporation NV43 [GeForce 6600
 LE] (rev a2)
 
 How can I add
 this discussion to your bug report at bugs.freedesktop.org
 as further evidence of the problem?
 
 Thank you a thousand times!
 Rick

 with an ATI card, the boot parameters
 "radeon.modeset=0" or "nomodeset"
 work.  So on the second Yaboot screen, I type either
 "Linux radeon.modeset=0" or "Linux
 nomodeset" to disable KMS.  For machines with Nvidia
 cards, you can do either "Linux nomodeset" or
 "Linux nouveau.modeset=0".  To make the boot
 parameters permanent so you don't have to type them in
 anymore, add them with the "append" line to your
 yaboot.conf like this:
