On Asus EeePC 1005PE, BIOS version: 0901 (03/04/2010), Kubuntu Lucid Beta 1, KDE environment :
- With "normal" default boot command, LCD brigthness keys [Fn]-[F5] and [Fn]-[F6] behave completely erratically, which is a real pain. - Booting with "acpi_osi=Linux", LCD brigthness keys behave properly (in a linear fashion) but it seems that KDE doesn't get information about brightness, i.e. LCD brigthness key don't result in a "level bar" appearing on screen when used. - Also "cat /proc/acpi/video/VGA/LCDD/brightness" shows a "current" level that doesn't change even when brightness is actually modified by use of the hotkeys. - Booting with "acpi_osi=Linux acpi_backlight=vendor" options as BlackSir suggests (thanks BlackSir !) make both LCD brigthness keys behave properly (in a linear fashion) and now KDE is aware of them (using the hotkeys now make the "brightness level bar" pop-up on screen). - OTOH I now have : # cat /proc/acpi/video/VGA/LCDD/brightness <not supported> But I guess I don't care about that "<not supported>" as long as everything now actually works ;-) -- hotkeys adjust brightness non-monotonically on EEEPC 1005PE https://bugs.launchpad.net/bugs/512567 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
