@Alejandro- Thanks for your report that the patched 'inverted- backlight' kernel (from comment #56) fixes it for your HP dm-4 notebook... Do you still have the Acer Aspire 4736Z that you mentioned in #27, and could you test it on that machine?
@Riccardo- Be sure to try the patched kernel along with using the kernel parameter "acpi_backlight=vendor" as described on the 'inverted- backlight' PPA details page (linked from comment #56) -- some systems will need that parameter to enable the patched code. -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/779166/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
