On my Asus W5G00AE:
- I had the issue "screensaver backlight stuck off, system looks hung" - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/872652 -
- Updated to kernel 3.0.0-15 using the update manager.
After the update, after the grub selection menu the screen is black, then I get some very thin vertical lines all over the screen, which slowly fade to black, leaving me with a black screen and no login menu.
Here's a picture taken of the moment the thin lines appear: http://www.flickr.com/photos/23115157@N05/6798325597/
I tried the 3.0.0-17 kernel proposed in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/919350, but without any luck: the result is the same as with 15.
I therefore have:
- kernel 14 working, but with the bug #872652 (backlight does not work after resuming from screensaver)
- kernel 15 and 17 not booting up, yielding thin white vertical lines for a couple of seconds, which fade to black |

== SRU Justification ==
Impact: An i915 regression in 3.0.0-15.24 causes some systems to have display issues. An unsigned value is being treated as signed, causing the SSC being used when it shouldn't be.
Fix: Upstream backport that changes the type of the variable from unsigned to signed.
Verification: Verified to fix the regression on LP #925350.
