Kernel-Log

Hello everybody.
I've got a problem with the Nouveau Driver and KMS.
My video card is a 9600GT.
I built Nouveau with this tutorial :
http://nouveau.freedesktop.org/wiki/InstallNouveau  
So , I’ve got a new kernel with Nouveau module activated, I’ve got also the
last version of libdrm and xf86-video-nouveau. 
But when I tried to launch this new kernel ,I’ve got a black screen and then
the monitor switch off just after the launch of KMS.
I've got the same problem with experimental packages of Debian.

Maybe the hand-over of nouveaufb does not go well depending on the previous fb driver used (if any), see here: http://nouveau.freedesktop.org/wiki/KernelModeSetting.

To check I suggest you launch your system with the "VGA=normal" parameter on the command line.

If that works, just change the fb driver used; if not... Then my guess was bad, sorry.

At first I didn't see vga=792 in your command line so may be I am wrong ?? (there was a hand-over problem of nouveaufb with vesab but it has been fixed long ago).

This bug is invalid.It's not a true bug but a bad configuration.
My videocard has two dvi port used not the good DVI port . 
I use now the good one and nouveau driver work fine with kms  .
