Confirmed, deleting .gconf/desktop/gnome/peripherals/keyboard/host- perseus/0/%gconf.xml and starting a new session got it working again. Thanks for that data point.
Now to find out why that setting affects it... ** Description changed: Binary package hint: gnome-power-manager [regression from 8.04] I'm not sure about the root cause of this yet, but starting here. Pressing the brightness up/down keys on my ThinkPad T61 no longer changes the brightness of the LCD backlight. This worked fine in 8.04, and at some point in Intrepid as well. When I press the brightness-up key, I see two ACPI events: video LCD0 00000086 00000000 ibm/hotkey HKEY 00000080 0000501 brightness-down is similar: video LCD0 00000087 00000000 ibm/hotkey HKEY 00000080 0000501 In xev, I see KeyPress and KeyRelease events forXF86MonBrightnessUp and XF86MonBrightnessDown, respectively. However, the backlight is not actually changed, and gnome-power-manager does not display the brightness level OSD (both of which worked in 8.04) + WORKAROUND: gconftool-2 --set --type bool + /desktop/gnome/peripherals/keyboard/host-perseus/0/numlock_on false + ProblemType: Bug Architecture: amd64 DistroRelease: Ubuntu 8.10 Package: linux-image-2.6.27-5-generic 2.6.27-5.8 [modified: lib/modules/2.6.27-5-generic/modules.pcimap lib/modules/2.6.27-5-generic/modules.dep lib/modules/2.6.27-5-generic/modules.ieee1394map lib/modules/2.6.27-5-generic/modules.usbmap lib/modules/2.6.27-5-generic/modules.isapnpmap lib/modules/2.6.27-5-generic/modules.inputmap lib/modules/2.6.27-5-generic/modules.seriomap lib/modules/2.6.27-5-generic/modules.alias lib/modules/2.6.27-5-generic/modules.symbols] ProcCmdLine: root=UUID=305dde78-d20a-4248-aaf4-09447b7c5791 ro quiet splash ProcEnviron: LC_COLLATE=C PATH=/home/username/bin:/usr/lib/ccache:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/sbin:/usr/sbin:/usr/games:/usr/lib/surfraw LANG=en_US.UTF-8 SHELL=/bin/zsh ProcVersionSignature: Ubuntu 2.6.27-5.8-generic SourcePackage: linux -- ACPI brightness events no longer work on ThinkPad T61 https://bugs.launchpad.net/bugs/280646 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
