[Bug 779166] Re: Upgrade to version 11.04, disable the laptop display back light
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.. Try this guys, who knows it can help you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/779166 Title: Upgrade to version 11.04, disable the laptop display back light -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 779166] Re: Upgrade to version 11.04, disable the laptop display back light
using "acpi_backlight=vendor" as kernel parameter doesn't work for me :( however, some people found solution from this thread: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/752165 in my case, its true that I can get my backlight work again by using setpci command and add it to my rc.local file. But when i change my screen resolution or running apps that needs to change screen resolution, my screen blank again :( thats why i recommend to set a keyboard shortcut to run an executable file containing setpci command, so whenever we change resolution and blank screen again, all we need to do is only press that keyboard shortcut. at least it helped me a little. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/779166 Title: Upgrade to version 11.04, disable the laptop display back light -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
