JimBo, 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. ** Tags added: bios-outdated-1.14 needs-upstream-testing regression- release ** This bug is no longer a duplicate of bug 765438 8086:2a42 On startup, the backlight is off on laptop ** Description changed: After update to Natty, when the system boots, grub's menu is ok, but after, lcd is getting black (even in console and recovery mode). This bug occurs with kernel 2.6.38-8 (and also with proposed version : 2.6.38-9 - I tried), but not with last version : 2.6.35-28 ! - My fix : - 1- Boot with old kernel version (2.6.35-28) - 2- Add the line : - setpci -s 00:02.0 F4.B=0 - to my /etc/rc.local (this puts the LCD backlight to Max, only in xorg). - 3- Reboot. + + WORKAROUND: Boot with old kernel version (2.6.35-28).
