X Fails to Start after installation of driver 180.44 on Ubuntu 9.04 RC with 7600GS

[blakzer0]

After installing a fresh install of the new Ubuntu 9.04 RC and installing all the necessary packages listed in the installation thread using driver 180.44, X now fails to start. The X Server complains no screens have been found. I am running an Nvidia 7600 GS. I've attached my X.org configuration file and the nvidia-bug-report.log.

I've tried doing a fresh install and using the drivers provided by Ubuntu. All versions provided by Ubuntu produce the same results. I've even added the:

Section "ServerFlags"
	Option 	"IgnoreABI" "True"
EndSection

to no avail. If its note worthy my machine has two 7600GS SLI'ed together.

This is a long standing problem that I have found no solution to. I'm currently still using Ubuntu 8.04 with the 173.14.12 binary drivers installed and they are working perfectly. Previously I attemped to upgrade to 8.10 and received the same error as now.

Any help would be greatly appreciated!

This is the same X server bug as in this thread: http://www.nvnews.net/vbulletin/showthread.php?t=131602

Thank you so much! That post you directed me to fixed the problem. I don't know how I didn't come across the error. I suppose I never thought it was related to the SLI considering it used to work before. I always thought it was related to the XServer.

For everyone else out there this is the method I used to fix it from the other post. Boot your computer and when x fails to start press Ctrl+Alt+F1 to drop to a shell. Login in with your user name and password and type:

sudo nvidia-xconfig -a
sudo /etc/init.d/gdm/restart

Thanks Aaronp. Although you think the driver should automatically detect two cards and run the nvidia-xconfig with the -a flag? Just a thought.

FYI, I threw together a couple of Ubuntu PPA builds for 9.04 to test a fix for this. I'm still waiting for the i386 builds to finish, but the amd64 ones should work. You'll need the linux-image-2.6.28-11-generic, libpciaccess0, and xserver-xorg-core packages from there.
