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/KernelMainl ineBuilds . 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.
