Bug Description

Dell Latitude E6410

After upgrading to kernel version 3.0.0-15 via the Update Manager and rebooting, the laptop display was blank (after grub).

If connected to an external monitor via a Dell docking station, the external monitor displays correctly, but the laptop display remains blank.

Tried disabling and re-enabling the display via Unity System Settings, but the problem persists.

The display works correctly if I shut down and boot to kernel 3.0.0-14. The display remains blank during a warm reboot from kernel 3.0.0-15, so the shutdown is necessary to select a different version.

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2 kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). 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.

If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed the issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. If you believe this bug does not require upstream testing, please add the tag: 'kernel-upstream-testing-not-needed'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Let me know if you want to try bisecting and need help. In parallel, I will continue to bisect and post test kernels. Currently, git states we are about 5 test kernels away from identifying the commit that caused this regression.

Question - I was doing a "fakeroot debian/rules clean" between each build. Is this a necessary step, or can the build environment properly handle partial builds?

Do you need to keep bisecting? We've already found the guilty commit.

I don't think it is necessary to run a "fakeroot debian/rules clean" between each build. However, it doesn't hurt to start with a clean tree.

I'll build a test kernel with commit e9925217e61dd3594f81b415f2b7e077426f208f reverted for other folks affected by this bug. I'll post a link to the kernel shortly.

I don't think it has been released yet. In the mean time, you can
probably keep using 3.0.0-14, or you can temporarily use the packages that
Joseph posted (above).

I don't know if the issue is the same or not, but on my Asus W5G00AE:

- I had the issue described in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/872652

- Updated to kernel 3.0.0-15 using the update manager.

After grub, 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.

Tried the 3.0.0-17 kernel proposed here, 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
