xev correctly recognizes the buttons as XF86MonBrightnessDown and XF86MonBrightnessUp.
In System Settings -> Keyboard & Mouse the display brightness keys are correctly recognized as brightness up and down when clicking "Custom key" for a random action and pressing those buttons. This means that X11 and Qt do know that the buttons are pressed. Probably the bug is in KDE, then? Btw, this is a regression from Kubuntu 9.10. ** Changed in: udev (Ubuntu) Status: Invalid => Confirmed -- Monitor brightness can not be controlled by hotkeys https://bugs.launchpad.net/bugs/500613 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
