No changes to X are required; it seems to be working properly. Thanks for the analysis, Bryce. I'm attaching a debdiff which implements that change. I don't see any cases in the code where it would be appropriate to treat these keysyms differently with a modifier, since they're all special-purpose hotkeys: gpm_button_xevent_key (button, XF86XK_PowerOff, GPM_BUTTON_POWER); gpm_button_xevent_key (button, XF86XK_Sleep, GPM_BUTTON_SUSPEND); /* should be configurable */ gpm_button_xevent_key (button, XF86XK_MonBrightnessUp, GPM_BUTTON_BRIGHT_UP); gpm_button_xevent_key (button, XF86XK_MonBrightnessDown, GPM_BUTTON_BRIGHT_DOWN); gpm_button_xevent_key (button, XF86XK_ScreenSaver, GPM_BUTTON_LOCK); gpm_button_xevent_key (button, XF86XK_KbdBrightnessUp, GPM_BUTTON_KBD_BRIGHT_UP); gpm_button_xevent_key (button, XF86XK_KbdBrightnessDown, GPM_BUTTON_KBD_BRIGHT_DOWN); gpm_button_xevent_key (button, XF86XK_KbdLightOnOff, GPM_BUTTON_KBD_BRIGHT_TOGGLE); 2. On the Thinkpad T61 specific issue, I discussed it with Peter Hutterer. It seems to be that on this hardware, the numlock key doesn't actually send events when the fn is pressed so we have no way of knowing that it is pressed. This was verified via gdb on the xserver. Scroll lock and numlock are shared, so fn has to be pressed to trigger numlock. So it seems to be either a hardware or kernel bug. I will open that one as a separate bug. -- - mdz -- 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 Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Status in “gnome-power-manager” source package in Ubuntu: Triaged Status in “linux” source package in Ubuntu: Triaged Bug description: Binary package hint: gnome-power-manager Problem: The state of the numlock key affects how the brightness switching keys work. The OCD display does not display. On some systems (e.g. Thinkpad 61's), it also prevents brightness from changing. This seems to be a new behavior in Intrepid, and not reproducible on Hardy A further issue on Thinkpad T61's is that the numlock key does not signal toggle off properly. This can be seen in xkbwatch, which shows that some modifiers are not getting turned off when numlock is toggled off. Original Report: [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 0086 ibm/hotkey HKEY 0080 501 brightness-down is similar: video LCD0 0087 ibm/hotkey HKEY 0080 501 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 -- Marc Jauvin 514-905-6500 http://register4less.com -- 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 Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
