[Kernel-packages] [Bug 910536] Re: 8086:2a42 [Acer Aspire 5736Z] Screen too dark, no backlight, unusable X
Bug still present in Ubuntu 14.04. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/910536 Title: 8086:2a42 [Acer Aspire 5736Z] Screen too dark, no backlight, unusable X Status in “linux” package in Ubuntu: Expired Bug description: I just did a fresh install of Precise on a Acer Aspire 5736Z with intel GMA 4500. When I booted the installer from a USB, the screen is OK in the boot menu (non-X) but as soon as X starts, the backlight of the screen turns off making the screen almost black, and thus unusable. Pressing Fn+Left Arrow does not increase screen brightness. Also pressing Fn+F6 (backlight on/off does not work). At the moment Precise is impossible to install on Acer Aspire 5736Z by a regular user. The laptop worked fine with Ubuntu 10.04, so this is a regression. Expected result: screen brightness should be higher and the user should be able to see what is on the screen. Workaround: If I boot the installer with kernel option acpi=off, the screen is still by default to dark, but pressing Fn+Left Arrow turns the backlight on and X becomes usable. After installation acpi=off is not remembered by the system, so I have to manually insert the option into Grub to make the change presistent and the user who boots the laptop needs to press Fn+Left Arrow at each boot after X has started (as it starts by default with backlight off and screen way too dark).

[Kernel-packages] [Bug 910536] Re: 8086:2a42 [Acer Aspire 5736Z] Screen too dark, no backlight, unusable X
Otto Kekäläinen, 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.
