[Bug 518002] Re: extensa 5635z backlight dimming not working. works with setpci.
Wolfgang Kufner, thank you for reporting this and helping make Ubuntu better. Lucid reached EOL on May 9, 2013. Please see this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We were wondering if this is still an issue in a supported release? 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 Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder. 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-v3.10-rc5 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 If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER 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.

[Bug 518002] Re: extensa 5635z backlight dimming not working. works with setpci.
I have the same issue with an Acer Aspire 5734z-4512. Backlights controls show a notification, but do not do anything. I upgraded from Maverick, and the old kernel that I had still shows brightness just fine, but the latest ones do not...it goes black...fast. I tried all the fixes on here, and nothing works. I'm at bug# 773820. :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/518002 Title: extensa 5635z backlight dimming not working. works with setpci. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I finally got around to testing the patched kernel and gnome-power- manager from https://launchpad.net/~kamalmostafa/+archive/linux-kamal- mjgbacklight . and that fixes it for me. Full hotkey backlight control. Tested both the 2.6.35 and the 2.6.38 kernel on maverick. Does this work for anybody else? Anybody it does not work for? ** Description changed: [Status] Happens on Maverick. Tested with 2.6.36 and 2.6.38 (see comment #37) kernel. Happens on Lucid. + + [Workaround/Fix 0] + Install the patched kernel and gnome-power-manager from https://launchpad.net/~kamalmostafa/+archive/linux-kamal-mjgbacklight by adding that ppa to your sources and upgrading your system (for maverick and natty). [Workaround 1] For Acer Extensa 5635Z with bios version V0.3219 or newer adding acpi_osi=Linux acpi_backlight=legacy as boot parameter resolves the issue. [Workaround 2] Write into the "Legacy Backlight Brightness" register (on [8086:2a42] hardware): first make sure you have that hardware ([8086:2a42]) at that address (00:02.0) by looking at the output of lspci -nn|grep VGA then try setpci -s 00:02.0 F4.B=a1 (a1 in the above line is just one example for a brightness value; you can use any two digit hexadecimal value, e.g: 80 for something like half brightness ff for full - better avoid 00 or be prepared for pitch black) + better avoid 00 or be prepared for pitch black) Also see comments #28 and #32. And be careful where you point that setpci command. It might even damage your hardware.

Hi, Same issue on emachines E725 Tried different options in grub2: acpi_osi=Linux, acpi_backlight=vendor and legacy, acpi=off and none work out. Maverick: 2.6.38-020638-generic VGA: Intel Mobile 4 series IGP rev 09 When start ubuntu in 2.6.38, i cant see, but can go to gnome-command and launch the last command to setpci brightness to 77 and start to see !! and debug. Then, when close the lid with 2.6.38, backlight turn off and on, normally. Brightness control still not work. Only work setpci. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/518002 Title: extensa 5635z backlight dimming not working. works with setpci. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
