Lenovo G700 - Screen gets dark after startup

[Franz Altmüller]

I have a lenovo g700-notebook. i installed ubuntu 13.10. on monday. It was very tricky. On startup with Ubuntu-Install-USB-Stick after aprox. 30 secs. the screen got dark. I didn't know whats going on. so i tried starting several times. At least i mentioned that the brightness was at minimum (screen dark). The brightness-key allows to darken the screen absolutely, so you dont see what happens. At least i'd like to save the screen-brightness, but i'm unable to do this. On startup the brightness is always on 'dark'-mode and i have to brighten up the screen.

WORKAROUND: Increase brightness via F12.

Franz Altmüller,could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) 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-v3.12-rc7

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.

Hello Christopher,
 this is not a real 'bug' because there is no problem with it. But you should consider, that the initial state of screen-brightness should not be on 'minimum' as on newer lenovo-notbooks the minimum is 'darkness':

best regards
frank

The new kernel 3.11.0-15 solved this problem
