Package: udev Version: 164-3 Severity: minor -- System Information: Debian Release: 6.0 APT prefers squeeze-updates APT policy: (500, 'squeeze-updates'), (500, 'proposed-updates'), (500, 'stable') Architecture: amd64 (x86_64)
Kernel: Linux 2.6.37-ksamd64 (SMP w/8 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Keyboard configuration in /etc/default/keyboard: ... XKBMODEL="pc105" XKBLAYOUT="de" XKBVARIANT="nodeadkeys" XKBOPTIONS="" ... I send this bug because information in /usr/share/doc/udev/README.keymap.txt give the advice for fixing broken keys by sending a bug report to https://bugs.launchpad.net/udev/+bugs this leads to an error page on the bug system. So I give the information on this way and hope it will reach the maintainer. Nethertheless, I have some broken keys on my laptop Acer Aspire 8930 sourced by the multimedia extension part of the keyboard called 'Cine Dash Multimedia' by Acer. I take a look how udev handle keymap for hotkeys and found that in squeeze by udev system an additional keymap is loaded by rule /lib/udev/95-kemap.rules. Additional keymap loaded on this machine is by default debian system: /lib/udev/keymaps/acer. Platform information: $cat /sys/class/dmi/id/sys_vendor Acer $ cat /sys/class/dmi/id/product_name Aspire 8930 end of Platform information Broken keys (all on Cine Dash Multimedia Area, kernel scan code): 0xCA, 0x83, 0x89, 0x92, 0x9E My solution: 1) adding a keymap file /etc/udev/keymaps/acer-aspire-8930 ## begin of file /etc/udev/keymaps/acer-aspire-8930 ## additionals for Acer Aspire 8930 ## if acer keymap (part of distribution debian squeeze) is load too, ## this are additional kernel scan code -> kernel key code mappings 0xCA prog3 # key 'HOLD' on cine dash media console # normally need no system/programm function, # because only disable touch events on # cine dash keys 0x83 rewind # key 'FAST REWIND' on cine dash media console 0x89 fastforward # key 'FAST FORWARD' on cine dash media console 0x92 media # key 'ARCADE' on cine dash media console 0x9E back # key 'BACK' on cine dash media console ## end of file /etc/udev/keymaps/acer-aspire-8930 2) adding a local rule /etc/udev/rules.d/96-keymap-local.rules taking same structure than found in /lib/udev/rules.d/95-keymap.rules: ## begin of file /etc/udev/rules.d/96-keymap-local.rules ... LABEL="keyboard_vendorcheck" ENV{DMI_VENDOR}=="Acer*", \ ATTR{[dmi/id]product_name}=="Aspire 8930", \ RUN+="/lib/udev/keymap $name /etc/udev/keymaps/acer-aspire-8930" ... ## end of file /etc/udev/rules.d/96-keymap-local.rules forcing reload of udev rules and trigger change event for input give new keys: $ /etc/init.d/udev reload $ udevadm trigger --subsystem-match=input --action=change In X (with above keyboard configuration!) new keys can be found now with X keysms: XF86Launch3 # key 'HOLD' on cine dash media console XF86AudioRewind # key 'FAST REWIND' on cine dash media console XF86AudioForward # key 'FAST FORWARD' on cine dash media consol XF86AudioMedia # key 'ARCADE' on cine dash media console XF86Back # key 'BACK' on cine dash media console With default behaviour of the system (loading keymap /lib/udev/keymaps/acer) and my modifications all keys work now as expcted. Perhaps you can include this additionals in further updates or this may be helpfull for something else. Some remarks: it would be helpfull if there can be found more information about adding custom rules to the distributions udev system without breaking updates by aptitude or similar. Google around don't help here, bringing up only very old informations about how to make a local manipulation of system behaviour.
