Blank screen with Ubuntu 3.8.0-0.2-generic

I upgraded my Acer laptop to Ubuntu 3.8.0-0.2-generic from the Raring repositories today. I get a blank screen when I boot up with no text or gui. I can tell that the system is starting correctly and I can access the machine via ssh. I can get the screen to work if I add 'nomodeset' in /etc/default/grub. However, doing so prevents me from changing screen brightness from the maximum value. I tried using 'ubuntu-bug linux-image-3.8.0-0-generic' to submit a bug report, but it is complaining that it is a mainline kernel. Can someone point me in the right direction to report this bug? This is a regression from the previous 3.7 kernel.

Thanks,
Ryan

I just upgraded my Dell D 3100 and I get this EDID error at bootup but then it goes to boot and works normally after that. I had to reset the themes to Ambiance because the desktop was borked .. but not blacked out.

@op are you using closed source drivers?

reason why i ask:

It is like the screen is shutting off. It goes from the bios splash to nothing - no text, plymouth, or X. My system uses nVidia Optimus. I currently have bumblebee and nvidia-current installed, but it does it without them installed, too. I think it is happening very early in the boot process. I created a bug report on bugzilla.kernel.org since I couldn't figure out how to do it with Launchpad.

I have the same problem with my ThinkPad SL500 2746-P3G (Intel 4500MHD Graphic).

"Solution":
Install Linux 3.7.2 from here:
http://kernel.ubuntu.com/~kernel-ppa...v3.7.2-raring/

Download:
linux-headers-3.7.2-030702-generic_3.7.2-030702.201301111424_amd64.deb
linux-headers-3.7.2-030702_3.7.2-030702.201301111424_all.deb
linux-image-3.7.2-030702-generic_3.7.2-030702.201301111424_amd64.deb
linux-image-extra-3.7.2-030702-generic_3.7.2-030702.201301111424_amd64.deb

Install:
sudo dpkg -i *.deb

With Linux 3.7.2 my System boots without any problems.

There is a kernel update available today 3.8.0-0.3 do you still have the same problem?

The problem persists on Ubuntu 3.8.0-0.3-generic. I am currently using Ubuntu-3.7.0-7.15 without any problems.

I just upgraded to 3.8.0-03 and rebooted, every thing works ok here:

I am also using SNA acceleration with good results so far.
