I think my problem is located in the fact that there I have no real ACPI-support for my Acer-model. The brightness control via the hotkeys seems to be done by the BIOS not by any ACPI-event. Even the available "acer-acpi" module doesn't support my Travelmate C200 series notebook. I hardly have access to ACPI-functions via the proc filesystem. I only get following answers if i try to access any of the ACPI-stuff:
#cat ./acpi/video/VGA/LCD/brightness <not supported> So it can be concluded that it is an issue of ACPI-support. Maybe the other people affected can confirm this? -- "Display brightness" slider does not show up on Dell Latitude D810 https://bugs.launchpad.net/bugs/116464 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
