Is the "local" display completely shut off? (no sign of backlight, i.e. just a bad brightness setting)

Have you tried pushing the key combination for switching between local/external/combined display a couple of times? (The blue Fn + one of the F#-keys with monitor[s] next to it)

Have you tried booting without an external display connected?

[Jens Elbaek (jens-elbaek)]

Right now the screen is totally black. I discovered the working second
screen because someone tried it for me. They actually tried to boot another
system (read Windows) and that worked perfectly. When I boot I see the
mashines own welcome ("e") and maybe there are some purple on the screen.
After that, it's all black.

After rebooting, I discovered by chance that is not totally correct. I
happened to have a very bright lamp shining rigt into the primary screen.
And I could in fact see the icons of Ubuntu. I signed on and the desktop
apeared but only when I shine the lamp against is. Otherwise it is black.
It's kind a stange... I tabed the Fn-key and the >-key in order to increase
the light on the screen but it had no effect.

I hope this will help solving the problem. If not, please do not hesitate to
contact me for further information.

Status changed to 'Confirmed' because the bug affects multiple users.

Jens Elbaek, 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? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

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

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
