black screen right after grub

[mescalinum]

just upgraded using update-manager -d. all went fine, but on reboot (and on every boot), I see "GRUB loading", then screen goes black, including backlight -or maybe only backlight-

boot continues, as I see hdd led blinking. I'm able to turn off using soft-power-button

forgot to add some info:
kernel: 2.6.32-12-generic
hardware: Sony VAIO W11S1E

recent findouts:
appending acpi=off makes the backlight stay on

2.6.32-10-pae-generic is the last kernel that doesn't exhibits this problem
maybe this bug is dup of bug #510571 ?

btw the -10 kernel makes ubuntu start in low graphics mode :-(

same problem with 2.6.32-13

Hi mescalinum,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 515134

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
