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
