This bug isn't a duplicate of bug #224636. The laptop mentioned there has NVIDIA graphics and an ambient light sensor that messes up with brightness settings. The asus x5dij and b80a have no such sensor and use the Intel GMA 4500MHD.
Therefore I unlinked the bugs. I posted some debugging information erroneously in #224636 that I'll repeat below. The conclusion I draw from them: 1. The bug is a kernel / video driver bug and has got nothing to do with gnome-power manager. (It occurs with kubuntu as well) 2. It still occurs with Karmic Alpha 2 Also theres the output of dmidecode, lspci and uname attached. As Scott did yesterday, I'd appreciate if a member of the kernel team can take a look at this bug again, since we're now sure it's a kernel bug. Now the debugging information (only the hotkey-troubleshooting, not for gnome-power-manager, see #224636): Gnome-power-manager and gnome-settings-daemon are killed. Keyevents reported by xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p' : keycode 232 = (keysym 0x1008ff03, XF86MonBrightnessDown), state = 0x0 keycode 232 = (keysym 0x1008ff03, XF86MonBrightnessDown), state = 0x0 keycode 233 = (keysym 0x1008ff02, XF86MonBrightnessUp), state = 0x0 keycode 233 = (keysym 0x1008ff02, XF86MonBrightnessUp), state = 0x0 (In both cases the two events are reported instantly, not on key down / key up.) This is before reloading video module. After that xev doesn't report keyevents anymore. acpi_listen events are strange before reloading: key brightness up produces always (except for the counter, of course): video LCDD 00000086 00000000 hotkey ATKD 00000011 0000007e and brightness down: video LCDD 00000087 00000000 hotkey ATKD 00000020 000000fa for the brightness down key, every press that is precedes by an "brightness down" keypress produces two ATKD-events: video LCDD 00000087 00000000 hotkey ATKD 00000020 000000fb hotkey ATKD 00000020 000000fc That's not the case for brightness up. After reloading the events seem ok, as I am really able to access the whole brightness scale. LCDD events are absent: hotkey ATKD 00000020 0000005d hotkey ATKD 00000020 0000005e hotkey ATKD 00000020 0000005f hotkey ATKD 00000020 00000060 hotkey ATKD 00000011 0000000b hotkey ATKD 00000012 0000000a hotkey ATKD 00000013 00000009 hotkey ATKD 00000014 00000007 hotkey ATKD 00000015 00000005 hotkey ATKD 00000016 00000003 hotkey ATKD 00000017 00000002 hotkey ATKD 00000018 00000002 hotkey ATKD 00000019 00000002 hotkey ATKD 0000001a 00000001 hotkey ATKD 0000001b 00000001 hotkey ATKD 0000001c 00000001 hotkey ATKD 0000001d 00000001 hotkey ATKD 0000001e 00000001 hotkey ATKD 0000001f 00000005 hotkey ATKD 0000001f 00000006 hotkey ATKD 0000001f 00000007 hotkey ATKD 0000001f 00000008 hotkey ATKD 0000002e 00000001 hotkey ATKD 0000002d 00000001 hotkey ATKD 0000002c 00000001 hotkey ATKD 0000002b 00000001 hotkey ATKD 0000002a 00000001 hotkey ATKD 00000029 00000001 hotkey ATKD 00000028 00000002 hotkey ATKD 00000027 00000002 hotkey ATKD 00000026 00000002 hotkey ATKD 00000025 00000003 hotkey ATKD 00000024 00000005 hotkey ATKD 00000023 00000007 hotkey ATKD 00000022 00000009 hotkey ATKD 00000021 0000000a hotkey ATKD 00000020 00000061 hotkey ATKD 00000020 00000062 hotkey ATKD 00000020 00000063 ** Attachment added: "bug_report_files.tar.gz" http://launchpadlibrarian.net/29199248/bug_report_files.tar.gz -- display brightness asus; function keys not working https://bugs.launchpad.net/bugs/368506 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
