[Bug 779166] Re: Upgrade to version 11.04, disable the laptop display back light
Diogo Coelho, thank you for reporting this and helping make Ubuntu better. Natty reached EOL on October 28, 2012. 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 replace-with-bug-number 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.

@cgonzalez and anyone else: Since the screen also goes dark when resuming from suspend or other purposes, and rc.local doesn't get run at that time, I've also added the relevant setpci command to root's crontab, to be executed every minute. That way, the screen isn't black for more than a minute.

[Bug 779166] Re: Upgrade to version 11.04, disable the laptop display back light
Here is a workaround that did the trick on my acer 7715 with GMA4500 chip: The following command has solved my problem. sudo setpci -s 00:02.0 F4.B=00 The best is to have this command executed automatically at start up. You can do that by including that command in your /etc/rc.local file. To achieve this start up pc the pc with a 10.04 Live USB / Live CD. Go into the /etc/rc.local of the installed ubuntu 11.04 on your HD and insert sudo setpci -s 00:02.0 F4.B=00 (without quotes) before the exit 0 command. My rc.local looks like this: #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will exit 0 on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. sudo setpci -s 00:02.0 F4.B=00 exit 0 Hope this will solve problem.

I have same problem.. Mine is Acer Aspire 4736 with Intel GMA 4500M. Linux - 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux I run this command under no-backlight condition on terminal (I still can read my screen under flashlight): sudo setpci -s 00:02.0 F4.B=00 and my back light is back! but back light is off again after reboot, need to run that command again :( All I did was add the setpci command into sudoers file (sudo visudo) so i don't need to type password when running setpci, and make a new executable file contains that command, then make new startup entry to run that executable file every startup. Now i have my back light function normally every startup..
